  • Prior herbicide use—not irrigation—is critical to herbicide efficacy

    Crop and herbicide use history are more critical to herbicide efficacy and environmental safety than the timing and amount of irrigation water used, according to Agricultural Research Service (ARS) scientists. ARS plant physiologists Dale Shaner and Lori Wiles made this discovery from ongoing experiments on two irrigated fields at Colorado State University (CSU) at Fort Collins, Colo. Shaner and ...

  • How much water is used for irrigation in European agriculture?

    Agriculture plays a large role in the management of water in the EU. However, there is little consistent information on water use in irrigation. New EU supported research has estimated how much water is used for irrigation in European countries, providing a framework to analyse agricultural pressures on water quantity. Water scarcity is an increasing problem in the EU and the situation is ...

  • Improved soil water sensors aid in irrigation management

    Agriculture, a large user of water for irrigation, is under pressure to reduce water use. Increased urban population growth has created more competition for limited water supplies. While growers have used soil moisture probes to aid in irrigation management in the past, earlier probes required maintenance or were expensive or inadequate.  New electronic sensors have been developed that require ...
