Titre : CROP PRODUCTION WITH IN-SITU USE OF SHALLOW SALINE GROUNDWATER AND REUSE OF DRAINAGE WATER

Identification : 5302-13000-009-05T

Pays : Etats Unis

Durée : Aug 25, 2001 à Jan 30, 2005

Domaine : Management of Saline and Sodic Soils and Salinity ; Alfalfa ; Water resources ; Soil

Partenaire : AGRICULTURAL RESEARCH SERVICE PARLIER,CA 93648

Objectifs
Demonstrate methods of drainage water volume reduction within a water district while maintaining sustainable crop production and active management of the subsurface drainage system using modifications that are suitable for previously installed subsurface drainage systems in arid and semi-arid areas.

Descriptif
Determine the salt movement in the rootzone of safflower and salt tolerant alfalfa (SW9720) and the salt accumulation in the rootzone over the length of the project. Determine the water quality changes of the shallow groundwater. Determine the forage quality of salt tolerant alfalfa (SW9720) for each irrigation treatment. Develop modifications to subsurface drainage systems that can be used to regulate flow and water table position on existing subsurface drainage systems. Characterize water table response and drainage discharge with respect to field modifications of drainage systems
