Crop Yield and Profitability Response to Salinity Model

This decision support tool is intended to help policymakers and Groundwater Sustainability Agency (GSA) managers identify areas unsuitable for sustainable and profitable agriculture and prioritize them for multi-benefit land repurposing to reduce agricultural water demand. The tool is also intended to help growers predict yield and profitability as a function of irrigation water salinity.
