Gis-Based Environmental And Economic Analysis Of Integrated Crop-Livestock Production Systems In Southern Iowa, U. Sunday Tim, Robert W. Jolly, Daniel Otto

Leopold Center Completed Grant Reports

Crop and livestock production are important economic components for many rural com­ munities. In 1992, Iowa led the nation in corn and hog production, and ranked second, third, seventh, and eighth, respectively in soybean, cattle and calves, poultry, and dairy cow pro­ duction. Livestock and livestock products generated over 64% of the state's total cash farm receipts during 1992—more than $6.5 billion sales at the farm level.

Agricultural and Biosystems Engineering Publications

Spatial decision support systems are used to plan production systems and direct the implementation management strategies that are compatible with environmental protection goals. They enable resource managers to select appropriate production technologies that minimize environmental damage, and evaluate alternative management practices. This article describes a spatial decision support system (SDSS) developed to facilitate planning and management of environmentally sound livestock production. The SDSS integrates a geographic information system, spatial and biophysical modeling, and a knowledge-based system into an interactive tool to select suitable watershed land areas for siting livestock production, to select fields for manure application, and to determine the ...
