After a lien has been perfected, an action may be brought to enforce such lien in the district court of the county in which some part of the crop or livestock is located. A lien-notification statement may be amended, except for the retail cost of inputs, by leave of the court in the furtherance of justice. A lien is extinguished if the lien is not enforced within 18 months after the lien-notification statement is filed.
