An agricultural production input supplier filed a financing statement to perfect its statutory lien against the debtors' crops and crop proceeds, but the financing statement did not contain the information required by the Nebraska agricultural production inputs lien statutes, so the lien was unperfected. Under the Uniform Commercial Code's priority rules, a perfected security interest has priority over a conflicting unperfected agricultural lien, so a lender's prior perfected security interest took priority in the available proceeds.
