The overall goal of the SARE/Water Quality project was to determine whether economic incentives offered by recent environmental provisions of Federal farm program are sufficient to induce Western Corn Belt/Northern Plains farmers in environmentally sensitive areas to adopt sustainable fa practices and systems. To attain this goal, four case farms were chosen involved in this study based on their size, soil types, cropping systems, topography, and management in the Big Sioux Aquifer study area. Case Farm No. 2 is located in Moody County and followed a corn-soybean oats rotation on the acres focused on in the analysis prior to enrollment the Integrated Crop Management (ICM) program. It is a dry-land operation used conventional tillage prior to enrollment in the ICM program. The total operation consists of 1,858 acres, with 710 acres under the ICM program focused on 299 of those ICM acres in our analyses. Lamo and Clamo soils up the majority of the ICM crop acres. These are medium to fine-textured soils overlying a shallow drinking water aquifer.
