(1). A security interest in crops is a production-money security interest to the extent that the crops are production-money crops.
(2). If the extent to which a security interest is a production-money security interest depends on the application of a payment to a particular obligation, the payment must be applied:
(a). In accordance with any reasonable method of application to which the parties agree;
(b). In the absence of the parties' agreement to a reasonable method, in accordance with any intention of the obligor manifested at or before the time of payment; or
(c). In the absence of an agreement to a reasonable method and a timely manifestation of the obligor's intention, in the following order:
(i) To obligations that are not secured; and
(ii) If more than one obligation is secured, to obligations secured by production-money security interests in the order in which those obligations were incurred.
(3). A production-money security interest does not lose its status as such, even if:
(a). The production-money crops also secure an obligation that is not a production-money obligation;
(b). Collateral that is not production-money crops also secures the production-money obligation; or
(c). The production-money obligation has been renewed, refinanced or restructured.
(4). A secured party claiming a production-money security interest has the burden of establishing the extent to which the security interest is a production-money security interest.
