Location: Delta Water Management Research Unit
2012 Annual Report
Objective 2: Develop economical and environmentally sound irrigation and drainage management tools, practices, and technologies that conserve water and protect regional water resources and supplies. (1.1.2, 1.3.1, 1.3.2) 2a: Quantify water quantity and quality as a result of the implementation of conservation practices. 2b: Test the practice of incorporating existing soil moisture technology in agricultural water management to reduce irrigation water use.
The SY is a collaborator on a successful grant for research related to the irrigation management; Conservation Innovation Grant (CIG) (Arkansas State University). The research project is a collaborative effort between USDA-ARS, USDA-NRCS, Judd Hill Foundation, Delta Plastics, University of Arkansas and Arkansas State University.
The SY collaborated with various working groups on the monitoring component of nine separate Mississippi River Basin Initiative (MRBI) Cooperative Conservation Partnership Initiative (CCPI) proposals. Five proposals were funded for FY 2012-2015: Middle Cache River Project, Tyronza River Watershed, Grande Prairie Watershed, Bayou Meto, Arkansas County, and Bayou Meto, Middle.
The SY is a co-principal investigator on a Conservation Innovation Grant proposal: “Building the capacity for edge-of-field monitoring of conservation through field demonstration, regional coordination, training and outreach”. Collaborators include University of Arkansas and Arkansas State University.
The SY submitted a grant proposal to the producer state support program of Cotton, Inc. to improve irrigation water management practices for Arkansas cotton growers.
The SY was invited to participate in a grantsmanship workshop through the Southern Region Directors of Research and Extension to develop a multi-state proposal that address regional concerns entitled “Addressing the fate of nutrients in the Lower Mississippi River Valley to the Gulf of Mexico”.
The SY gave an invited field presentation to approximately 60 participants on a watershed tour for Arkansas state senate and congressional members of agricultural committees in Jonesboro, AR, in July 2012.
The SY presented virtual training to approximately 10 extension personnel on the use and implementation of an irrigation planning tool. The SY was invited to meet with state senator’s staff to discuss agricultural needs of the region in April 2012. The SY was invited to present on irrigation techniques for the Fayetteville Army Reserve in June 2012.
The SY attended an irrigation meeting for regional research and extension to discuss irrigation scheduling in St. Louis, MO, in June 2012.
