Résumé
Although the irrigated land area utilizing microirrigation in Kansas is only 1 to 2 %, it is anticipated the microirrigated land area will continue to grow as water resources become more stressed and as the need for greater water productivity (more crop per drop) increases. Microirrigation is well suited for automation and has the ability to spoon-feed both water and nutrients just in time to the crop’s root system through targeted delivery either through subsurface drip irrigation (SDI) or mobile drip irrigation (MDI).Both SDI and MDI systems can be combined with improved water management technologies such as remoting sensing of crop environmental parameters (weather, soil water, crop water stress, etc.) to improve overall irrigation management. Additionally, when irrigation management is improved, there are crop yield advantages that can be obtained when other cultural practices are concurrently improved such as through fertigation, hybrid selection, and/or plant density increases. In essence, the reduction in limitations from one limiting factor, moves the management needs to other factors and the cycle can continue indefinitely governed by economics and scientific knowledge constraints.Corn and grain sorghum are major feed grains in the region and are often irrigated to increase production. In some cases, the best economic and environmental strategy will be to reduce irrigation and this strategy may be imposed by either governmental or groundwater availability constraints. In other cases, the best strategy may be to intensify irrigated crop production on a smaller land area to increase the water productivity. Microirrigation is well-suited to both of these approaches for these crops.In this project, Kansas State University will continue its long-standing efforts to develop microirrigation methodologies suitable for Great Plains agriculture that are water and nutrient efficient and economically profitable. The project will involve field and laboratory research, computer modeling as well as technology transfer to get the technologies in the hands of producers.

Objectifs
Develop and evaluate irrigation systems, designs, technologies, and management practices that are sustainable and can increase water productivity. Improve methods of irrigation scheduling that are particularly applicable for microirrigation. Develop, evaluate, and adapt models as tools to improve system design, management, and production. Expand technology transfer products for a diversity of stakeholders to promote adoption of water-saving irrigation strategies.
