Analysts who have studied how to increase the efficiency of the CRP agree that one simple step can result in dramatic gains; enroll only land with high environmental benefit-to-cost ratios. Too much of current CRP land was brought in with very low ratios, either because the contract rental rates were set too high, or the land offered too few environmental benefits.
