A security interest in crops is a production-money security interest to the extent that the crops are production-money crops.
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:
To obligations that are not secured; and
If more than one (1) obligation is secured, to obligations secured by production-money security interests in the order in which those obligations were incurred.
A production-money security interest does not lose its status as such, even if:
The production-money crops also secure an obligation that is not a production-money obligation;
Collateral that is not production-money crops also secures the production-money obligation; or
The production-money obligation has been renewed, refinanced, or restructured.
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.
