The purpose of this lease supplement is to encourage cooperation between tenants and landlords to obtain and maintain needed conservation practices on a rented farm. Rent charges should reflect cost and risk incurred by farming practices. Conservation practices and improvements will not be made unless agreed to in advance and the tenant has the necessary machinery and management ability. A tenant is not likely to make an important contribution to soil conservation unless additional costs are shared or the tenant is assured repayment of an unexhausted value in case the lease agreement ends. Soil loss control is beneficial to both the landlord and tenant.
