Research Project:
Remote Sensing and Precision Irrigation to Improve Water Nutrient and Pesticide Use Efficiency
Location:
Southeast Watershed Research
Project Number: 6602-13000-019-00
Project Type:
Appropriated
Start Date: Jan 09, 2001
End Date: Jan 08, 2006
Objective:
Develop, test, evaluate and transfer precision pivot irrigation systems to: improve application efficiencies of water, fertilizer, and pesticides; and and minimize water quality impacts. Develop, test, evaluate and transfer remote sensing technologies and modeling and assessment approaches to incorporate remote sensing into water and chemical management at field and watershed scales.
Approach:
Approaches will be developed that combine new or improved remote sensing and precision irrigation management technologies with germplasm development to improve the management options of peanut, cotton, and pearl millet growers of the southern coastal plain. Remote sensing technologies will be incorporated into the development of variable rate water, fertilizer and pesticide application systems that will tailor treatments to variations in soil and plant condition. Databases (e.g., soils, vegetation, topography, hydrology, etc.) will be developed having suitable resolution for use by targeted user communities (small, medium and large management operations), and that are easily linked to remotely sensed information using GIS approaches. Demonstrations will be developed quantifying the utility of such information in decision-making by individual producers.
