570A.5  Priority of lien.
  Except as provided in this section, an agricultural supply dealer lien that is effective or perfected as provided in section 570A.4 shall be subject to the rules of priority as provided in section 554.9322. For an agricultural supply dealer lien that is perfected under section 570A.4, all of the following shall apply:
  1.  The lien shall have priority over a lien or security interest that applies subsequent to the time that the agricultural supply dealer lien is perfected.
  2.  Except as provided in section 570A.2, subsection 3, the lien shall have equal priority to a lien or security interest which is perfected prior to the time that the agricultural supply dealer lien is perfected. However, a landlord’s lien that is perfected pursuant to section 570.1 shall have priority over a conflicting agricultural supply dealer lien as provided in section 570.1, and a harvester’s lien that is perfected pursuant to section 571.3 shall have priority over a conflicting agricultural supply dealer lien as provided in section 571.3A.
  3.  A lien in livestock feed shall have priority over an earlier perfected lien or security interest to the extent of the difference between the acquisition price of the livestock and the fair market value of the livestock at the time the lien attaches or the sale price of the livestock, whichever is greater.
