3. A financing statement filed to perfect a lien in the farm products must include a statement that it is filed for the purpose of perfecting a landlord's lien. Notwithstanding section 554.9515, such financing statement shall continue to be effective until a termination statement is filed.

4. Within twenty days after a landlord who has filed a financing statement receives a written demand, authenticated as provided in article 9 of chapter 554, from a tenant, the landlord shall file a termination statement, if the lien in the farm products has expired or if the tenant is no longer in possession of the leased premises and has performed all obligations under the lease.
