Agronomy Computer Programs
Revised Universal Soil Loss Equation (RUSLE)
This model can be used to determine sheet and rill erosion on cropland.
Soil Conditioning Index (SCI)
An Excel spreadsheet customized for Idaho that is used to calculate the Soil Condition Indices.
Surface Irrigation Design & Evaluation (SRFR)
This model is used to evaluate surface irrigation systems in terms of efficiency, deep percolation, outflows, etc.
Surface Irrigation Soil Loss Equation (SISL)
(Released by Technical Guide Notice 145 dated June 20, 2000). This model is used to predict irrigation induced erosion from furrow irrigated crops.
