    Four Aces Farms, Inc. (“Four Aces”) appeals from the district court’s
    declaratory ruling and final judgment order concluding an oral 50/50 crop share
    agreement supplemented its written cash rent lease agreement with Ronald
    Peck. We are not persuaded Peck established his case by the requisite degree
    of proof and we therefore modify the district court’s declaratory ruling and
    judgment.
    I.     Background Facts and Proceedings
    Ronald Peck is a retired farmer and businessman who owns 690 acres of
    farmland in Poweshiek County, Iowa. Peck farmed the 690 acres himself until
    November 2006, when he decided to lease the property to Four Aces. Four
    Aces, an Iowa Corporation, is operated by Douglas Helm, a former math teacher
    who began farming full time in 2001. Mark Kennett, an agronomics consultant
    and Peck’s then-partner in a chicken litter1 application venture, facilitated the
    landlord-tenant relationship between Peck and Helm.
    Helm prepared a farm lease for the 2007 crop season which was signed
    by the parties in November 2006. The lease provided that Four Aces would pay
    Peck $195 per acre for 689.5 acres, with payment of $67,226.25 due on March 1,
    2007, and $67,226.25 due on December 1, 2007. The lease contained only two
    additional terms: that Four Aces would pay $0.10 per bushel for rent of storage
    bins (and would be responsible for electricity and propane associated with the
    1
    “Poultry litter” includes poultry feces and bedding. Farmers use the poultry litter “as
    fertilizer on their fields, and often sell or barter it to others.” Att’y Gen. of Oklahoma v.
    Tyson Foods, Inc., 
    565 F.3d 769
    , 774 (10th Cir. 2009).
    3
    use of the bins), and that Peck would provide “3 ton of chicken litter at the rate of
    $20 per ton” to be paid for by Four Aces.2
    Four Aces proceeded to farm the land. During the summer of 2007, when
    it appeared it would be a very good crop year with rising prices, Kennett talked to
    Helm.    Under the circumstances, it was thought Peck would “be expecting
    more—more money.” The two discussed how to keep Peck satisfied so that
    Four Aces could continue renting the farm.           They discussed paying Peck a
    bonus—one that would satisfy Peck but still maintain a profit for Four Aces. Four
    Aces paid the 2007 rent pursuant to the lease terms. Helm testified that at some
    point he told Peck he would be paid some type of bonus. In September 2008,
    after the 2007 harvest had been sold, Four Aces paid Peck a “bonus” of
    $61,251.72, and Helm presented Peck with a detailed accounting showing how
    he had calculated this extra payment. Specifically, Helm reached the amount by
    taking half of the “Shared Income” (gross income minus “Shared Expenses”),
    reduced by the rental payments Four Aces had already made to Peck. Helm
    later testified he chose the method of calculation to be “fair to both of us” in an
    effort to “help to continue things for ’09 and beyond to maintain good relations” so
    that Peck would continue to lease the farm to Four Aces. Peck maintained the
    payment and method of calculation were in accordance with their “50-50
    agreement.”
    Four Aces continued renting Peck’s land. In November 2007, the parties
    signed a written lease for the 2008 crop year, which was identical to the 2007
    2
    The lease also contained a handwritten provision that “this contract is void as of March
    1, 2008.”
    4
    lease except for an increase in the rent amount to $200 per acre and omission of
    the chicken litter provision. As it had done the previous year, after the 2008 crop
    was marketed, Four Aces presented Peck with an additional payment than that
    required by the written lease—this time in the amount of $27,497.05. Again,
    Helm gave Peck a detailed accounting showing how he calculated the extra
    payment, using the same method as he had for the 2007 payment. Helm later
    testified he made the additional payment to Peck in order “to incentivize, to keep
    continue renting the farm and maintain good relations.” In contrast, Peck testified
    the parties continued to have an oral agreement that required Four Aces to share
    profits with him.
    The 2009 crop year unfolded similarly. In December 2008, the parties
    signed a written lease for the 2009 crop year, which was identical to the 2008
    lease but for an increase in the bin rental rate to $0.16 per bushel. In the fall of
    2010, Four Aces again presented a summary of the profitability of the 2009 crop
    year. This time, however, the summary showed that the cash rent Four Aces
    paid to Peck exceeded the profits from the farm, and Four Aces made no
    additional payment for the 2009 crop year. Peck later testified the rent required
    by the lease only represented a minimum and that the oral agreement for profit
    sharing continued to exist.
    The parties did not enter into a new written lease for the 2010 and 2011
    crop years. Four Aces continued to rent and farm Peck’s property. Peck later
    testified that the 2009 lease was “carr[ied] over” and continued in effect through
    the 2010 and 2011 crop years.
    5
    The parties’ relationship began to sour in 2011 after a disagreement arose
    when a Four Aces employee loaded 2010 grain from Peck’s farm into a trailer
    partially full with Four Aces’s grain. Peck felt Four Aces was “cheating” him by
    commingling the grain.    Helm agreed the employee’s actions were improper.
    The incident forced Four Aces to estimate the amount of grain in the load that
    came from Peck’s farm.
    While wintering in Florida in early 2011, Peck fell ill, which prevented him
    from farming 61.7 acres owned by his wife, Beverly, as he had in prior years.
    Peck contacted Helm seeking Four Aces’s assistance with Beverly’s land, and
    Helm “said he would help out.” Peck later testified he had no kind of agreement
    with Helm about the rent, while Helm testified they agreed Four Aces “would just
    cash rent it . . . under the same lease agreement” it had with Peck.
    In August 2011, Peck sent a “Notice” to Four Aces that the contract
    regarding Peck’s land and Beverly’s land was “cancelled” for the 2012 crop year.
    In the fall of 2011, as in prior years, Four Aces prepared a summary for
    Peck showing the profitability of the 2010 crop year. Based on the calculation,
    Four Aces offered to pay $19,218.14 to Peck.         Peck refused to accept the
    payment, later testifying that it was not “calculated proper, and it was not honest
    per our agreement.” According to Helm, he later called Peck and offered him
    more money in an effort to continue Four Aces’s status renting the farm, though
    he could not recall the amount he offered.
    On November 1, 2011, Peck sent Four Aces a letter instructing Four Aces
    not to market any of Peck’s grain and stating, “I will notify you when I desire for
    the grain to be sold.” Peck filed a Uniform Commercial Code (UCC) Financing
    6
    Statement covering “[a]ll crops grown upon” the property, establishing a landlord
    lien.
    Helm later testified the grain was not Peck’s (“It was [Four Aces’s] grain”),
    so Four Aces disregarded Peck’s letter and sold the grain from the farm. A
    disagreement arose as Four Aces was removing the grain stored on Peck’s
    property, eventually involving law enforcement and the parties’ attorneys. Helm
    presented the sheriff with a written lease for the 2011 crop year; Helm had
    signed Peck’s name on the lease, but later testified Peck had “directed” him to do
    so.
    In a November 2011 letter to Peck, Four Aces (through its attorney)
    detailed what it represented as “payment in full” for the outstanding amounts
    Four Aces owed Peck under the written lease, and did not mention a crop share
    agreement between the parties. The letter included four checks to Peck from
    Four Aces: $68,950 for “2011 land rent/2nd half”; $9272 for “storage 2010”;
    $10,817.60 for “2011 storage”; and $12,340 for “2011 cash rent” for Beverly’s
    61.7 acres. In the letter, Four Aces alleged Peck violated the lease by chopping
    and chiseling the corn stalks, thereby retaking possession of the properties early
    and preventing Four Aces from harvesting the corn stover 3 when the lease
    granted Four Aces possession of the properties until March 1, 2012. In closing,
    the letter included a formal demand for release of the UCC Financing Statement
    3
    Corn stover is defined as “corn stalks, leaves, and cobs remaining above ground on the
    field after the harvest of corn kernels.” Jack W. Leverenz, Corn Flakes Aren’t Just for
    Kellog’s, A Look at Corn Stover and Its Effect on Leasing in the Landlord Tenant
    Relationship,

     (2012).
    7
    filed by Peck, asserting that Four Aces “has performed all obligations under the
    Farm Lease between the parties.”
    Peck’s attorney returned the checks to Four Aces’s attorney with a letter
    stating:
    For the years since 2007, the agreement has been that Four Aces
    Farms would lease Mr. Peck’s land on a 50/50 crop share basis
    with a minimum of $200 per acre. It is also our position that
    Beverly Peck leased her land to Four Aces Farms, Inc. for the 2011
    crop year on the same terms as the existing lease between Ron
    Peck and Four Aces Farms.[4]
    Knowing it would not be renting Peck’s farm any further, Four Aces did not
    offer any additional or bonus payments for the 2011 crop year. At the request of
    Peck’s attorney, Four Aces created a summary of profitability for the 2011 year,
    which included calculations for Beverly’s 61.7 acres.
    In March 2012, Peck filed a petition for declaratory judgment and for
    accounting against Four Aces.5 Peck alleged the parties’ lease agreement was
    in fact a “50/50 crop share lease” that also required Four Aces to pay the
    minimum amount stated on the written lease. Peck claimed the written leases
    did not represent the full agreement between the parties. Peck further alleged
    Four Aces’s year-end summaries incorrectly incorporated crop sales from other
    Four Aces farms when calculating prices received for Peck’s crops. Finally, Peck
    claimed Four Aces did not lease the additional 61.7 acres, rather Four Aces
    merely performed the farm work for him.           Peck requested the district court
    declare, among other things, that the leases “required that [Four Aces] pay a
    4
    The letter further stated it was not the full statement of Peck’s position and that the
    purpose of the letter was to return the checks.

    Peck also named Helm, personally, as a defendant, but Helm was dismissed as a
    defendant on June 9, 2014, leaving Four Aces as the sole defendant.
    8
    minimum rent based on cash and rent based on a 50/50 crop share”; a full
    accounting in order to determine the proper net income for each year; a judgment
    for the difference between that paid and owed based on this new accounting; a
    declaration that Peck was entitled to receive the 2011 crop from Beverly’s 61.7
    acres from Four Aces, and a declaration that Four Aces was entitled to
    compensation for planting, spraying, and harvesting the crop on Beverly’s land at
    ordinary and customary custom rates.
    Four Aces filed an answer and counterclaim, denying the existence of a
    50/50 crop share agreement. Four Aces further claimed it leased Beverly’s 61.7
    acres on terms identical to the written leases between Four Aces and Peck. In a
    counterclaim, Four Aces alleged that in 2011, Peck prevented Four Aces from
    harvesting corn stalks from the properties in violation of Iowa Code section
    562.5A (2011), and sought an order requiring Peck to reimburse Four Aces for
    the lost value of the unharvested corn stover. Other counterclaims and defenses
    are not at issue on appeal.
    In August 2014, following a one-day bench trial, the district court entered a
    declaratory ruling and judgment order in favor of Peck, concluding the parties
    had an oral crop share agreement supplementing the written farm lease:
    The parties’ division of farm profits originated during their initial
    associations as landlord and tenant for the 2007 crop year, and
    was sustained throughout their lease relationship. The meeting of
    their minds on sharing the farm’s production potential arose in oral
    discussions Peck had with Helm with the aid of Kennett, as the
    2007 crop was growing. Both parties realized they had a written
    lease in place for Four Aces to pay Peck $195 per acre in two
    installments; nonetheless, with the March 1st installment already
    paid, Peck and Helm refined their deal. It was in the summer of
    2007 when the crop was looking very good, that they agreed to
    incorporate a sharing of profits into the agreement.
    9
    In reaching this conclusion, the district court considered the testimony of Peck
    and Helm, as well as Kennett.6 The court found the previous course of dealings
    between the parties—especially the methodical nature with which the annual
    additional payments and summaries were made from Four Aces to Peck—to be
    significant in reaching its conclusion.
    The court determined Four Aces owed to Peck $19,218.14 for the 2010
    crop share; $9,272.00 for 2010-11 bin rent; $68,950.00 for the December 2011
    cash rent installment; $94,090.74 for 2011 crop share; $10,817.60 for 2011-12
    bin rent; and $12,400.00 for 2011 cash rent for Beverly’s land—a total of
    $214,748.48.
    The court found in Four Aces’s favor on its corn stover counterclaim,
    stating that by prematurely chiseling the corn stalks Peck denied Four Aces its
    leasehold right to recover the “full measure of the crop” pursuant to Iowa Code
    section 562.5A. The parties stipulated the value of the corn stover Four Aces
    was prevented from harvesting was $20,429.00. The court awarded Four Aces
    half of this amount—$10,214.50—finding Peck was entitled to half of the value of
    the stover. The court also credited Four Aces for $461.90, half the cost of a bin
    repair made by Four Aces.
    After off-setting the award to Four Aces on its counterclaim, the district
    court entered judgment in Peck’s favor in the amount of $204,072.08.               In
    6
    It is noted the district court reached its conclusions based upon a preponderance of
    evidence standard.
    10
    addition, the court ordered Four Aces to pay interest at a rate of five percent7
    from March 28, 2012, the date on which Peck filed the suit.8
    Four Aces appeals.
    II.    Scope and Standards of Review
    The standard of review for a declaratory judgment varies by how the case
    was tried. See Owens v. Brownlie, 
    610 N.W.2d 860
    , 865 (Iowa 2000). The
    parties agree the district court tried this case in equity. We conduct a de novo
    review of cases tried in equity. Iowa R. App. P. 6.907; Owens, 
    610 N.W.2d at 865
    . We give weight to factual findings made by the district court, especially
    regarding the credibility of witnesses, but we are not bound by them. Owens,
    
    610 N.W.2d at 685
    .
    III.   Parol Evidence
    Four Aces contends the district court “improperly considered parol
    evidence to modify the terms of an existing written contract.” Four Aces claims
    the parties’ written farm lease “set forth all terms needed to carry out
    enforcement of the agreements” and parol evidence of “[t]he alleged oral
    agreement” could not be used to vary or add to those terms.
    A. Error Preservation. Peck contends this issue was not preserved for
    review. As Peck points out, Four Aces never objected at trial to the use of parol
    evidence and the district court never ruled on the issue.
    7
    The district court cited to Iowa Code section 535.2(1)(b) in imposing the five-percent
    rate.
    8
    The date set by the district court from which the interest runs is not challenged by
    either party.
    11
    Four Aces counters that its submission of a pretrial brief—which included
    a claim that the court was precluded from considering parol evidence—preserves
    the issue for appellate review despite the absence of a ruling by the trial court on
    the issue. Although the parol evidence rule is a substantive rule of law, standard
    error preservation rules regarding the admission of evidence apply to parol
    evidence issues. See Top of Iowa Coop. v. Sime Farms, Inc., 
    608 N.W.2d 454
    ,
    470 (Iowa 2000). “It is a fundamental doctrine of appellate review that issues
    must ordinarily be both raised and decided by the district court before we will
    decide them on appeal.” Meier v. Senecaut, 
    641 N.W.2d 532
    , 537 (Iowa 2002).
    This case was tried in equity, and in such cases “‘the trial judge, while
    noting objections, may not exclude offered testimony’” in order to “preserve a
    complete record of the evidence for the trial and the appellate courts, leaving to
    them the rejection of inadmissible testimony in deciding the issues.” See O’Dell
    v. O’Dell, 
    26 N.W.2d 401
    , 416-17 (Iowa 1947) (quoting Rankin v. Schiereck, 
    147 N.W. 180
    , 182 (Iowa 1914)). Accordingly, at issue is not the admission of the
    parol evidence challenged by Four Aces, but the court’s consideration of that
    evidence.
    Throughout the one-day bench trial, Four Aces lodged no objections to
    evidence that arguably implicated the parol evidence rule. The pretrial brief that
    purports to raise the issue of parol evidence did not become a part of the record,
    though its existence is acknowledged by the parties.
    Four Aces claims that by considering the parol evidence when deciding
    the case, the district court implicitly ruled on the issue and that this, coupled with
    its argument in its pretrial brief, satisfies the preservation requirements. The
    12
    district court’s ruling refers to an oral agreement and Helm’s calculations and
    summaries as being evidence of an oral contract between the parties.              The
    inference could be drawn that the district court ruled against Four Aces by using
    the evidence in reaching its ruling. But without the benefit of objections at trial
    and Four Aces’s pretrial brief, this court cannot be sure which pieces of evidence
    were contested by Four Aces. The two requirements for preservation, that the
    issue be both raised and decided by the court, have not been convincingly
    established. See Meier, 
    641 N.W.2d at 537
    .
    B. Consideration of Parol Evidence. Bypassing this error preservation
    concern, see State v. Taylor, 
    596 N.W.2d 55
    , 56 (Iowa 1999) (bypassing error
    preservation problem and proceeding to the merits of the appeal), we do not
    conclude the district court erred in considering extrinsic evidence. “When an
    agreement is fully integrated, the parol-evidence rule forbids the use of extrinsic
    evidence introduced solely to vary, add to, or subtract from the agreement.”
    C & J Vantage Leasing Co. v. Wolfe, 
    795 N.W.2d 65
    , 85 (Iowa 2011).                  An
    agreement is fully integrated “when the parties adopt a writing or writings as the
    final and complete expression of their agreement.” 
    Id.
     The presence of an
    integration clause, while considered, is only one factor used in determining if the
    contract is integrated. See 
    id.
     Extrinsic evidence may be used to consider if the
    written contract is in fact fully integrated “despite the absence of . . . ambiguity on
    the face of the document.” In re Eickman Estate, 
    291 N.W.2d 308
    , 312 (Iowa
    1980).
    Once it is established that an agreement is not fully expressed in writing,
    extrinsic evidence may be used to find the entire contract. See Sol Popofsky Co.
    13
    v. Wearmouth, 
    248 N.W. 358
    , 360 (Iowa 1933); see also Cargill, Inc. v.
    Fickbohm, 
    252 N.W.2d 739
    , 741 (Iowa 1977) (allowing oral evidence to show the
    delivery date term when that field on a form contract had been left blank). “A
    contract may . . . be partially written and partially oral.” Cargill, Inc., 
    252 N.W.2d at 741
    . As expressed in Sol Popofsky Co.:
    [W]here the entire agreement is not fully expressed in the writing,
    and where part of the agreement is oral and part in writing, parol
    evidence may be introduced to show the entire contract . . . . If the
    parol part concerns a matter not covered by the writing, then, the
    written and parol parts being harmonious, the parol part may be
    shown along with the written.
    
    248 N.W. at 360
    . The caveat is that the “parol terms may not directly contradict a
    clear term of the written agreement.” 
    Id.
    Four Aces argues that the written lease captures the entire agreement
    between the parties and thus prevents the consideration of parol evidence. The
    language Four Aces relies on reads: “Tenant agrees to pay the owner $200 per
    acre” and “[t]he land rent is . . . $137,900.”
    At the outset, we observe the lease lacks an integration clause, which is
    one factor to consider, although it is not dispositive. See C & J Vantage, 795
    N.W.2d at 85.        Describing the written lease as skeletal would be generous
    considering the major bones it is missing. There is no legal description of the
    leased parcels.9 The written lease does not describe the type of crops to be
    grown and, in fact, did not even require Four Aces to farm the land. Nor did the
    written lease preclude Four Aces from using the land for non-farming purposes.
    9
    The    lease only indicates the 690 acres of leased parcels were located somewhere
    within   four square miles of land. The parcels were located in four separate sections of
    land.     A section is defined as “[a] piece of land containing 640 acres, or one square
    mile.”   Black’s Law Dictionary 1473 (9th ed. 2009).
    14
    Four Aces could have used the land to stage a Wadena-like rock festival, or it
    could have operated a salvage yard on the property. Other terms typically found
    in a farm lease are absent. The absence of these significant terms supports the
    court’s finding that the lease was not the full extent of the parties’ agreement—
    the parties obviously knew the location of the leased land and that it was to be
    used for farming, but simply did not memorialize these terms in the written lease.
    The “totality of the evidence” is to be considered when determining if a
    written agreement is fully integrated. See id. The surrounding circumstances
    and vagueness of the lease persuasively point toward a non-fully integrated
    agreement between the parties, which allows for the consideration of parol
    evidence to show the unwritten portion of that agreement. See Sol Popofsky
    Co., 
    248 N.W. at 360
    . The district court properly considered the parol evidence,
    so we next turn to the question of whether or not Peck established that there was
    a 50/50 oral crop share agreement.
    IV.    Oral Agreement
    Peck argues that “[i]n order to give any real meaning to the written
    contract entered into between the parties, it would be necessary for the parties to
    also have an oral contract,” and “the course of conduct between the parties over
    the 2007 through the 2011 farm years [evidenced] the parties’ oral agreement.”
    The parties’ written agreement,10 entitled “Farm Lease,” provides in full:
    This lease is made between Ron Peck, owner and Four Aces
    Farms, tenant. This lease will be from March 1, 2009 to March 1,
    2010. The parcels of land are approximately 689.5 acres. The
    10
    Minor changes were made to the leases for the 2007, 2008, and 2009 crop years. For
    our purposes, we have used the 2009/2010 lease because that was the lease renewed
    due to lack of termination and in effect at the time the dispute between the parties arose.
    15
    parcels are located in Section 29 of Scott Township, Section 34 of
    Pleasant and Sections 5 & 6 of Jackson Township of Poweshiek
    County. Tenant agrees to pay the owner $200 per acre.
    The land rent is $200 x 689.5 acres = $137,900.
    The tenant will pay $68950 on March 1, 2009.
    The tenant will pay $68950 on December 1, 2009.
    The tenant will pay bin rent at 15 cents per bushel. The
    tenant will also pay electricity and propane used.
    The written agreement includes no reference to any agreement between
    the parties to share crop profits or other revenues or expenses. But that does
    not preclude an oral agreement co-existing with the written agreement. This type
    of relationship has been acknowledged by the supreme court:
    An examination of our lease cases wherein oral evidence was
    offered to show a collateral agreement shows where the parol
    evidence is of an agreement which did not vary or affect any of the
    terms of the written lease, but was beyond and independent of it, it
    was admissible. In [Witthauer v. Wheeler, 
    150 N.W. 46
    , 47-48
    (Iowa 1914),] plaintiff leased from defendant, in writing, for two
    years a 2400 acre ranch only 200 acres of which was tillable, as a
    farm and stock ranch. The crop rent was fixed in the writing but no
    mention was made as to any agreement between the parties jointly
    conducting the business of stock raising, the parties to share
    equally in the increase of said stock.
    Gordon v. Witthauer, 
    138 N.W.2d 918
    , 920 (Iowa 1965). And as we observed in
    the preceding section, this is precisely the type of situation where extrinsic
    evidence may be admitted to show the complete duties and obligations of the
    parties. See Witthauer, 150 N.W. at 47-48 (affirming admission of evidence of
    “conversations between the parties prior to the execution of the written lease [to
    rent land to use as a farm and stock ranch], which as claimed resulted in an
    agreement between them that appellant was to stock the ranch with cattle which
    were to be cared for by the appellee, and the increase of the same was to be
    divided between them”); see also Parriott v. Levis, 
    195 N.W. 578
    , 579 (Iowa
    16
    1923) (“[T]here may be at the same time two contracts coexistent, one of which
    is in writing and complete in itself, and the other of which is in parol and complete
    in itself. . . . In such case the written contract is not altered, varied, or changed
    by proof of the coexistent oral contract.       The writing embodies the written
    contract, and the oral evidence established the parol contract. Even in such a
    case, evidence of a contemporaneous parol or collateral agreement is only
    available when it refers to a matter on which the writing is silent, and which is in
    no manner inconsistent with the terms of the written instrument.”).
    That having been said, it is Peck’s burden to prove there was an oral
    agreement for a 50/50 crop share. Hawkeye Land. Co. v. Iowa Power & Light
    Co., 
    497 N.W.2d 480
    , 486 (Iowa 1993) (“A party who seeks recovery on a
    contract has the burden to prove the existence of the contract.”). “[P]roof of a
    claimed oral contract must be clear, satisfactory and convincing.           A mere
    preponderance of the evidence is not enough.” Ehlinger v. Ehlinger, 
    111 N.W.2d 656
    , 659 (Iowa 1961). For evidence to be clear and convincing, it is necessary
    “that there be no serious or substantial doubt about the correctness of the
    conclusions drawn from it.” Raim v. Stancel, 
    339 N.W.2d 621
    , 624 (Iowa Ct.
    App. 1983). Although only a reasonable certainty an oral contract existed need
    be shown, the terms must be sufficiently definite to determine with certainty the
    duties and obligations of each party. Netteland v. Farm Bureau Life Ins. Co., 
    510 N.W.2d 162
    , 165 (Iowa Ct. App. 1993). “For a contract to be valid, the parties
    must express mutual assent to the terms of the contract.” Royal Indem. Co. v.
    Factory Mut. Ins. Co., 
    786 N.W.2d 839
    , 846 (Iowa 2010).
    17
    The written lease provides for cash rent only. To assure good relations
    and the ability to continue to farm the land, in 2008 Four Acres paid a bonus to
    Peck in connection with the 2007 crop year. The initial bonus was calculated by
    Helm in a format reflecting shared income and shared expenses much akin to a
    50/50 crop share less the cash rent previously paid. Before paying the 2008
    bonus to Peck, Helm discussed the use of a bonus with farm consultant Kennett.
    Bonus structures were familiar to Kennett, and he explained bonuses were paid
    by tenants to landlords because the changing grain markets caused negotiated
    cash rents to go “out of whack.” The use of bonuses that were not contractually
    required also did not violate any rules of the governmental agency, Farm Service
    Agency (FSA). Four Acres also similarly calculated and paid a bonus in 2009. In
    2010, because of reduced profits, no bonus was paid.         The landlord-tenant
    relationship then began to sour.
    Unfortunately, the calculation and payment of bonuses apparently left
    Peck with the impression that he was somehow entitled to a 50/50 sharing of
    profits—notwithstanding the unambiguous terms of the parties’ lease. It seems
    highly improbable that Helm would have agreed to Peck’s version of the contract
    terms because the contract would have run afoul of the FSA rules. Helm also
    had a logical reason for paying the bonuses—retaining the ability to farm the land
    for future years. Moreover, Peck presented no evidence of any conversations
    with Helm suggesting the parties agreed to a crop share arrangement with or
    without cash rent. At most, Peck testified, “It was a 50-50 agreement, which
    we’ve always done.” He referenced no specific conversations with Helm. On the
    18
    other hand, both Helm and Kennett testified about their conversation concerning
    providing a discretionary bonus to Peck.
    Other evidence also supports the position of Four Acres.             The written
    lease required full payment of bin rent and chicken litter by the tenant, which is
    inconsistent with a crop share arrangement where expenses are shared. Four
    Acres or Helm maintained the crop insurance on all the acres rented, and FSA
    forms reflected that Four Acres was the sole producer/operator. Further, Peck
    was not involved in any decision making, except to perhaps share his advice or
    predictions of the grain markets.11
    Upon our de novo review of the record, we conclude Peck has not
    established by clear, satisfactory and convincing proof that an oral 50/50 crop
    share agreement was ever reached between these parties pertaining to Peck’s
    land or Beverly’s land. There was no meeting of the minds concerning a crop
    sharing arrangement.      Accordingly, the district court’s declaratory ruling and
    judgment should be modified to strike the award to Peck of $19,218.14 for 2010
    crop share and $94,090.74 for 2011 crop share. Thus, Peck is entitled to recover
    11
    One commentator has acknowledged the existence of flexible cash rent arrangements
    in stating, “Flexible or adjustable cash leases set the rent based on the crop yield, the
    crop price, or a combination of these attributes.” Edward Cox, A Lease-Based Approach
    to Sustainable Farming, Part II: Farm Tenancy Trends and the Outlook for Sustainability
    on Rented Land, 
    16 Drake J. Agric. L. 5
    , 23 (Spring 2011). But in crop share
    arrangements,
    [t]ypically landowners contribute a share of the farm inputs and are more
    involved in land use decision making. This added involvement and risk
    can affect social security payments, taxes, estate planning, and the
    distribution of farm program payments. Simply stated, landowners would
    be more likely to be viewed as self-employed and more likely to be
    eligible for a share of any farm program payments.
    
    Id.
     Here the parties never committed to any formality of the bonus arrangement.
    Rather, it was left to the discretion of Four Acres. Further the only sharing Peck wanted
    to participate in was a share of the profits.

    $101,439.60 from Four Aces for 2020-11 bin rent ($9,272.00), 2011 cash rent
    installment ($68,950), 2011-12 bin rent ($10,817.60), and 2011 cash rent for
    Beverly’s land ($12,400).
    V.     Corn Stover
    As the district court found, “Peck took over during the fall of 2011 and had
    the corn stalks chiseled in for the 2012 crop preparations. That unilateral act
    before the lease end, denied the 2011 tenant [Four Aces] opportunity to harvest
    stover from 2011 corn production.” In view of the crop-share agreement it found,
    the court awarded Four Aces one-half the value of the stover.            Four Aces
    contends the district court “improperly awarded only one-half of the crop stover to
    Four Aces,” contending that it had the right to collect “the full stipulated value of
    the stover: $20,429.”
    As set forth above, the parties’ agreement did not include a 50/50 profit
    sharing arrangement. Pursuant to Iowa Code section 562.5A, in the absence of
    a written agreement to the contrary, “a farm tenant may take any part of the
    aboveground part of a plant associated with a crop . . . until the farm tenancy
    terminates.” This court recently interpreted this language as entitling a tenant to
    damages for the value of the destroyed corn stover when the landlord entered
    the property before the termination of the lease to perform fall tillage, preventing
    harvest of the corn stover by the tenant. See Slach v. Heick, No. 14-0539, 
    2015 WL 1546445
    , at *4, 18 (Iowa Ct. App. Apr. 8, 2015). Section 562.5A applies to
    leases that renew for lack of notice of termination after the provision’s effective
    date of July 1, 2010. See id. at *12, 15. Accordingly, section 562.5A applies to
    the parties’ lease for the 2011 crop year, as it was a renewal of the prior year’s
    20
    lease due to lack of termination on September 1, 2010.              See 
    Iowa Code §§ 562.6
    , 562.7. Four Aces was therefore entitled to the full value of the stover,
    not half as found by the district court. Accordingly, the district court’s declaratory
    ruling should be modified to credit Four Aces in the amount of $20,429, the full
    value of the crop stover from the 2011 crop.
    VI.    Interest Awarded on Amounts Tendered
    Four Aces claims the district court “improperly awarded Peck interest on
    amounts that Four Aces had previously tendered and Peck had rejected.” Four
    Aces contends it is not obligated for interest beyond the date of tender.
    The district court ordered that the judgment of $204,072.08 “shall draw
    interest at the annual rate of five percent, factored from March 28, 2012 [the day
    Peck’s lawsuit was filed].” Four Aces contends its November 21, 2011 letter and
    enclosed checks totaling $101,379.60 was an unconditional tender to Peck,
    rendering the district court’s award of interest on these amounts improper. A
    bona fide tender precludes the accrual of further interest on amounts due. See
    In re Estate of Zach, 
    131 N.W.2d 484
    , 486-87 (Iowa 1964). But the tender must
    be “absolute and unconditional” to be effective. Decorah State Bank v. Zidlicky,
    
    426 N.W.2d 388
    , 391 (Iowa 1988).
    Peck counters that language of Four Aces’s letter indicating the offered
    checks represented “payment in full” for the 2011 farm rent made the tender
    conditional—acceptance of which would form an accord and satisfaction
    discharging Peck’s claims against Four Aces.
    To constitute an accord and satisfaction . . . all that is
    necessary is that the money should be tendered in satisfaction of
    the claim; that the tender be accompanied with such acts and
    21
    declarations as amount to a condition that, if the money is taken, it
    is accepted in satisfaction. The conditions under which the tender
    is made, and the conduct of the party at the time of the tender,
    however, must be such that the party to whom it is tendered is
    given to understand that, if he takes it, he takes it in satisfaction of
    his claim, so far as the other party is concerned. He must either
    refuse or accept it. If he accepts it, he is bound. If he takes it, his
    claim is canceled.
    Shahan v. Bayer Vehicle Co., 
    162 N.W. 221
    , 223 (Iowa 1917).
    For the acceptance of the tender to be considered an accord and
    satisfaction, there must have been a genuine dispute concerning the amount
    due.   See Olson v. Wilson & Co., 
    58 N.W.2d 381
    , 386 (Iowa 1953).                 The
    November 2011 letter individually listed the amounts enclosed for the 2010-2011
    and 2011-2012 bin rents. There was no dispute at the time as to the amount of
    bin rent due to Peck. These amounts were provided on separate checks and
    Peck was free to accept them without the risk of discharging his claim.
    Therefore, the tender of $20,089.60 for bin rent was unconditional and the award
    of interest on this amount was improper. See Zidlicky, 
    426 N.W.2d at 391
    .
    The parties did have a dispute, however, over the nature of their land
    rental agreement. Peck had already rejected the 2010 “bonus” payment offered
    by Four Aces on the basis that it was not properly calculated. Peck’s letter
    instructing Four Aces not to market any of Peck’s grain was at direct odds with
    Four Aces’s contention that the leases had no crop share component.
    The existence of an accord and satisfaction is generally a question for the
    trier of fact. See Perin v. Cathcart, 
    89 N.W. 12
    , 13 (Iowa 1902). We conclude a
    reasonable trier of fact could have found the letter and accompanying
    payments—had they been accepted—constituted an accord between the parties
    22
    discharging Peck’s claim against Four Aces. See Seidler v. Vaughn Oil Co., 
    468 N.W.2d 474
    , 478 (Iowa 1991) (remanding to determine if plaintiff “knew or should
    have known” that accepting a check with “Full, Final Settlement for Damages”
    written on it was intended as a release of claims against the defendant); Perin,
    89 N.W. at 13 (stating an accord and satisfaction “need not be express, but may
    be implied from the circumstances”).      The tender of payment for the rental
    amounts, therefore, was conditional and did not preclude an award of interest
    See Zidlicky, 
    426 N.W.2d at 391
    . We therefore affirm the district court on this
    issue of awarding interest.
    We determined above that the rental amounts Four Aces owed to Peck
    totaled $101,439.60 and that Four Aces was entitled to a set-off of $20,429 for
    the stover. The parties do not challenge the district court’s set-off of $461.90 to
    Four Aces for a bin motor repair. Reducing the $101,439.60 by the two set-offs,
    Peck is entitled to $80,548.70.      The district court’s declaratory ruling and
    judgment should therefore be modified to reduce the amount subject to the
    interest award to $80,548.70.
    VII.   Conclusion
    In accordance with the above opinion, we modify the district court’s
    declaratory ruling and judgment as follows: (a) the awards to Peck of $19,218.14
    for 2010 crop share and $94,090.74 for 2011 crop share are deleted, (b) the
    amount of set-off to Four Aces for the crop stover from the 2011 crop is
    increased to $20,429, and (c) the amount subject to interest is reduced to
    23
    $80,548.70. We affirm the district court’s declaratory ruling and judgment in all
    other respects. Costs of the appeal are taxed to Peck.
    AFFIRMED AS MODIFIED.
