Project Number: 5310-13210-008-00
Project Type: Appropriated

Start Date: Dec 23, 2001
End Date: Dec 22, 2006

Objective:
Identify and quantify plant, soil, water, and environmental interactions that contribute to yield loss and morphological changes due to salinity. Develop crop growth simulation models, decision support systems, and information data bases which integrate and predict crop responses to salinity or provide information in easily-retrievable formats. Also, develop sustainable management options and alternatives that will avoid regional and on-farm crop losses due to salinity.

Approach:
Identify differential crop response to irrigation water chemistry; determine interactive effects of salinity and potentially toxic trace elements (selenium, arsenic, boron, molybdenum)on crop response and food safety; determine potential, long-term salinity hazard on crop species grown in the inland valleys of California; correlate remotely sensed thermal imagery and spectroradiometric measurements with physical, chemical, and physiological changes that occur in crops under salinity stress; develop decision support algorithms concerning best management practices for water quality and quantity considerations through the integration of crop, water, and geology data with available models for crop growth and the chemistry/physics of salt transport in soils.
