Two Central MN events in August: Irrigation Field Day and Rosholt Research Farm Field Day

Presentation at Field Day

Join us for two great events in August and learn about the latest irrigation and nutrient management research in central Minnesota. The Irrigation Field Day is on Thursday August 10, 2023. One week later is the Rosholt Research Farm Field Day on August 17, 2023.

Irrigation Field Day: August 10, 2023

University of Minnesota Extension invites you to a free field day at the Sand Plain Research Farm (SPRF) in Big Lake on Thursday, August 10th from 4:00 pm to 7:00 pm. The field day will highlight U of M research on advanced irrigation and nutrient management practices, and includes a complimentary dinner.

Many parts of Minnesota are currently facing drought conditions, and others are facing unusually dry conditions. This is our state's third year in a row of dry conditions, with almost no rain since early spring. In dry seasons when crop water demands are high, like the one we are experiencing right now, water availability for irrigation could be an issue later in the season. Using irrigation scheduling tools and advanced irrigation management practices, such as precision irrigation, can benefit the environment and improve farm profitability.

Different irrigation and nutrient management related topics will be covered including precision irrigation and nitrogen management in corn and potatoes, soil moisture sensing technology for irrigation scheduling, and enhanced efficiency fertilizers.


RSVPs are requested and can be found at


Free to attend


The farm is next to Knife River Corporation, which is located at 16491 157th St SE, Big Lake, MN 55309 (Google Maps). Extension event signs will direct you to the field day.

Rosholt Research Farm Field Day: August 17th, 2023

Join us Thursday August 17th for a field day at the Rosholt Research Farm from 9:00 am to 1:00 pm. Current research trials to be addressed include Kernza perennial grain, nitrogen fertilizer applications, cover crop and living mulches, and irrigation water management practices. A great line-up of speakers has committed to participating in the event representing the University of Minnesota, University of Minnesota Extension, Minnesota Department of Agriculture, and Pope and Stearns Soil and Water Conservation Districts.
