(a) Except as otherwise provided in subsections (c), (d), and (e) of this section, if the requirements of subsection (b) of this section are satisfied, a perfected production-money security interest in production-money crops has priority over a conflicting security interest in the same crops and, except as otherwise provided in section 9-327, also has priority in their identifiable proceeds.

(b) A production-money security interest has priority under subsection (a) of this section if:

(1) The production-money security interest is perfected by filing when the production-money secured party first gives new value to enable the debtor to produce the crops;

(2) The production-money secured party sends an authenticated notification to the holder of the conflicting security interest not less than ten or more than thirty days before the production-money secured party first gives new value to enable the debtor to produce the crops if the holder had filed a financing statement covering the crops before the date of the filing made by the production-money secured party; and

(3) The notification states that the production-money secured party has or expects to acquire a production-money security interest in the debtor's crops and provides a description of the crops.

(c) Except as otherwise provided in subsection (d) or (e) of this section, if more than one security interest qualifies for priority in the same collateral under subsection (a) of this section, the security interests rank according to priority in time of filing under section 9-322(a).

(d) To the extent that a person holding a perfected security interest in production-money crops that are the subject of a production-money security interest gives new value to enable the debtor to produce the production-money crops and the value is in fact used for the production of the production-money crops, the security interests rank according to priority in time of filing under section 9-322(a).

(e) To the extent that a person holds both an agricultural lien and a production-money security interest in the same collateral securing the same obligations, the rules of priority applicable to agricultural liens govern priority.
