摘要：The U.S. Department of Agriculture (USDA) accepted about 33.9 million acres of cropland into the Conservation Reserve Program (CPR) during 1986-89. This acreage was enrolled in nine separate sign ups under authority of the Food Security Act of 1985. CRP enrollment was extended through 1995 with passage of the Food, Agriculture, Conservation, and Trade Act of 1990. Three signup periods (the 10th, 11th, and 12th) were held in 1991 and 1992. About 2.5 million additional acres were enrolled in these signup periods under significantly revised program rules. No funds were appropriated for additional signups in fiscal years 1993-95. This report presents tables covering all CRP cropland enrolled in signup periods 1-12 and CRP cropland newly retired for each of fiscal years 1986-93.
