Chemigation
- Applying nitrogen with irrigation water – Basics of fertigation, irrigation systems, nitrogen sources, timing and rates, calibration, and management tips.
- Chemigation safety measures – The most significant risk of chemigation is the potential for accidental backflow of all or part of the chemical into the irrigation water source if the system is not properly set up, operated and maintained.

Outside resources
- The North Dakota Agricultural Weather Network provides weather data, including air and soil temperatures, evapotranspiration, and wind speed.
- Minnesota Department of Natural Resources – Growing degree day (GDD) tools, temperature, freeze/frost dates, evapotranspiration, soil temperature, and weather data from around Minnesota.
- Observed precipitation (National Weather Service)
- Water resources from MNDNR – Well permits, irrigation permits, groundwater management program.
The Irrigation Management Assistant (IMA) helps Minnesota growers improve irrigation efficiency across a variety of crops, including corn, soybean, potato, and other irrigated crops. The tool works best when using precipitation data close to your field and is optimized for Minnesota conditions through University of Minnesota research.
