Nutrient management dynamics in Northwest Minnesota corn production (Year 2)
This project will address the combined effects of fertilizer source and rate on nitrogen, phosphorus, and carbon dynamics from multiple perspectives: corn grain production, soil nutrient availability, and water quality.
Dialing in the Most Corn-Profitable and Environmentally Responsible Nitrogen Rate (Year 3)
The study will use the common approach to calculate EONRs by establishing several nitrogen rates from zero to well above where a corn response is expected.
Soil Health Partnership
The Soil Health Partnership is a farmer-led initiative fostering transformation in agriculture through improved soil health, benefiting both farmer profitability and the environment. Established in 2014 by the National Corn Growers Association, the SHP built a network of working farms, including four in Minnesota, it tests, measures and shares results of advanced farm management practices that will enhance sustainability and farm economics.
