Cropman: A Decision Aid to Assess Crop Production Strategies and Manage Risk

Thomas J. Gerik, Wyatte L. Harman and Jimmy R. Williams


ABSTRACT

CroPMan is a windows-based application of EPIC (Environmental/Policy Integrated Climate model) originally developed by USDA-ARS that simulates the interaction of natural resources (soil, water, climate) and crop management practices to estimate impacts on harvested crop yield, soil properties, soil erosion, profitability, and nutrient/pesticide fate. It is designed as a production-risk management aid to help agricultural practitioners optimize crop management and maximize production and profit, to identify limitations to crop yield, to assist growers with replant decisions, and to identify best management practices that minimize impact of agriculture on soil erosion and water quality. CroPMan is distributed on CD-ROM and operates under Windows® 98 and 2000 with 64 MB RAM. It is installed on a hard-drive (using 250 MB minimum). The databases for basic model operation are organized by agricultural region and contain baseline information for model operation so the user can perform basic operations with minimum effort, but the user can customize this information for his/her site-specific conditions and needs. Databases for model operation are currently available for Texas and Missouri, but can be constructed for other agricultural regions upon request and operation.
