SAREC Ag Systems Project (SASP)
Welcome! This is the homepage for the "Economic and environmental sustainability of conventional, reduced-input and organic western crop-range-livestock farms" study being conducted at the James C. Hageman Sustainable Agriculture Research and Extension Center (SAREC) near Lingle, WY. Commonly called the SAREC Ag Systems project (SASP), this long-term research investigates the economic and ecological sustainability of conventional, reduced input, and organic approaches in cash-crop and beef-calf production on crop-range-livestock farms. The plots form a base-line framework for additional research within each approach.
The parameters to be measured over the four-year study period include: 1. weed, pathogen, arthropod and nematode populations; 2. soil biological, physical, and chemical properties; 3. water use efficiency and soil moisture dynamics; 4. crop and forage growth, yield and quality; 5. livestock performance; 6. economic viability.
Our project has expanded to include analysis of soil quality and soil carbon sequestration and greenhouse gas emissions on irrigated and non-irrigated land in the agroecosystems of eastern Wyoming and western Nebraska.
