Water has a central role for all processes in and on the ground. During dry years and inferior stands during springtime, irrigation is vital for optimizing grain production. Knowledge about water-maintenance and water-economy are vital to develop long-term sustainable solutions for culture systems. In the water-committee we work with research and experimentation within water-maintenance and hydro-technology areas. The water-committee we are applying for funds from “Stiftelsen lantbruksforskning” for basic funding of field trials in irrigation.
