The United States has invested large sums of resources in conservation programs for agriculture over the past century. Beginning in 1985, the largest and most ambitious conservation program, the Conservation Reserve Program (CRP), was introduced with the dual goals of controlling supply and reducing soil erosion. As reported in Claassen et al. over $15 billion was spent in the first fifteen years and resulted in the retirement of about 10% of the total cropland across the country from active production.
