The purpose of this lease supplement is to encourage cooperation between tenants and landowners who wish to obtain needed improvements, facilities, and buildings on a rented farm. Often rented farms are in need of additional buildings, facilities, major repairs, or soil improvements. Many of the additions and improvements that are needed on a rented farm will not be made unless the tenant pays for part or all of the cost. But tenants are not likely to make important contributions toward farm improvements unless they are sure of repayment for any unexhausted value of their investments in case they have to discontinue farming the property.
