As the days grow longer and temperatures rise, farmers across Minnesota face crucial decisions regarding their fertilizer choices. DTN caught up with the University of Minnesota Extension to help guide producers through this process by offering expert advice on the highest-priority considerations to keep in mind.
Navigating Nitrogen Sources
A nutrient management specialist from the University of Minnesota Extension emphasizes the importance of selecting the right nitrogen source for early spring applications. According to their recommendation, anhydrous ammonia is the preferred choice, followed closely by urea. However, they caution against using anything containing UAN (urea ammonium nitrate), highlighting potential concerns with this particular nitrogen source.
Challenges with Phosphorus and Potassium
Another specialist weighs in on the application of DAP (diammonium phosphate) and MAP (monoammonium phosphate) during the early stages of spring. While these phosphorus and potassium sources can be beneficial, the main concern is ensuring sufficient moisture to dissolve them effectively. This underscores the importance of monitoring weather conditions and soil moisture levels before application.
Focusing on Fertilizer Budgets and Soil Health
Farmers must keep a close eye on their fertilizer budgets as they make this flurry of decisions. The experts stress the importance of conducting soil tests to determine specific nutrient requirements, ensuring efficient use of resources while promoting soil health and sustainability.
