Rotations: Influence and constraint from commodity programs

Abstract

AbstractRecent research and debate in sustainable agriculture has focused on the role of commodity programs in shaping rotation decisions. The commodity programs are often cited as obstacles to establishing long-term, diversified rotations. However, predicting which rotations would be practiced in the absence of commodity programs is difficult. How strongly commodity programs influence the rotation decision depends on the size of the economic incentive to participate and the percentage of cropland enrolled in the program. Data from the Agricultural Stabilization and Conservation Service (ASCS) were used to calculate the distribution of the percentage of cropland in corn base for each farm record at ASCS in the Corn Belt and Lake States in 1988. The distribution shows that the level of corn program enrollment varies widely. Many corn base acres are found on farms with high corn base enrollment levels, which potentially constrains the rotation choice. However, enrollment levels in the corn program do appear to allow the option of diversified rotations for many corn base acres in the Corn Belt and Lake States, even during the high corn price support years of the mid to late 1980s.
