WATER RESOURCES RESEARCH GRANT PROPOSAL

Project ID: 2003TX90B

Title: Quantification of Stochastic Crop-Water Production Functions and Net Profit-Water Functions for Agriculture on the Edwards Aquifer

Project Type: Research

Focus Categories: Agriculture, Irrigation, Water Use

Keywords: irrigation, groundwater resources management, farm profitability

Start Date: 03/01/2003

End Date: 02/28/2004

Federal Funds: $4182.00

Matching Funds: $10000.00

Congressional District: 5

Principal Investigators: Lee, Ju Young; Brumbelow, Kelly

Abstract: The Edwards Aquifer Authority of Texas, a regional governmental agency, has developed regulations that limit the amount of water agricultural producers can use for crop irrigation. Under these rules, farmers can use 2 acre-feet of irrigation water each year, but can sell 1 acre-foot on the open market. The emphasis of this project is to quantify the relationship of seasonal irrigation to crop water yields throughout the region. Advanced optimization techniques and physiologically based models of crop growth and development will be used to develop the crop water production function. Through this project, agricultural producers will be given additional information on how to make the best irrigation decisions when limited water supplies are available for irrigation.
