Many conservation practices — such as cover crops — have costs in the short-run, but also have environmental benefits, and the possibility of long-run economic benefits. Farmer tenants may be hesitant to make conservation investments on rented farmland, particularly because farmland leases often require an annual renewal. The annual renewal result in farmers bearing short-run costs without assurance of long-term benefits. Achieving greater adoption of conservation practices on rented farmland may require leasing adjustments, some of which could be longer-term agreements or additional partnership between landowners and farmer tenants.
