Economic Model of Deficit Irrigation II (spreadsheet)

This spreadsheet model calculates the net income for irrigated agricultural production. The model is designed to evaluate the economics of deficit irrigation (irrigation at less than the amount required to produce maximum yield).

Economic Model of Deficit Irrigation

The model calculates net income from a crop on a unit of land based on a quadratic crop water production function, amount of effective precipitation, irrigation efficiency, cost of the irrigation water supply, crop production costs, and revenue from selling the crop. The model includes potential income from leasing out saved irrigation water. All biophysical variables are defined in terms of the relative evapotranspiration. Net income is maximized by optimizing the amount of water consumed by the crop.

Java Newhall Simulation Model (jNSM)

The Java Newhall Simulation Model or jNSM is a mesoscale model that is appropriate for use in regional geospatial analyses that support the MLRA update of published digital soil geographic databases (SSURGO/STATSGO2). This software can be used with monthly, serially complete records from weather stations, Soil Climate Analysis Network (SCAN) stations, and local soil climate monitoring sensors.

NRCS Regional Conservation Partnership Program - Colorado River Basin

Irrigated agriculture is vitally important to the economy and quality of life in many areas of the Colorado River Basin. It also accounts for a significant share of the basin’s existing water use, shared among 33 million people in the United States plus 3 million in Mexico. Faced with historic drought conditions and water supply pressures, farmers, ranchers, Indian tribes and other water users are in urgent need of accelerated conservation on working agricultural lands. This dataset includes a printer-friendly CCA map and shapefiles for GIS.
