• When used with UAN and urea, Instinct® nitrogen stabilizer helps maximize yield and profit potential by inhibiting nitrification in the soil.
• The four reasons listed will act as encouragement to implement Instinct as part of a UAN and urea fertilizer program.
Improve return on investment by pairing nitrogen stabilizer with fertilizer. When used with urea ammonium nitrate (UAN) and urea, Instinct® nitrogen stabilizer maximizes yield and profit of corn by inhibiting nitrification in the soil.
Instinct is easily impregnated onto urea or mixed with UAN fertilizer solutions to protect nitrogen applications, preserving nitrogen availability during critical growth stages. Surface-applied UAN solution is susceptible to significant nitrogen loss by ammonia conversion . When you are losing nitrogen, yield air, and water quality can be compromised. It is important to understand what you are stabilizing when you mix a nitrogen stabilizer with UAN. 50% of UAN is urea, 25% is ammonium and 25% is nitrate. When stabilizing with a urease inhibitor or NBPT, you are only protecting from urea hydrolysis, which leads to ammonia volitization. Nitrification inhibitors protect 75% of the UAN from leaching and denitrification raising. Take a look at some of the figures about nitrogen fertilizer additives with UAN[1]:
Keep in mind that because UAN is a concentrated nitrogen solution, the solubility increases as the temperature rises. When UAN remains on the surface of the soil for periods exceeding two days, soil enzymes will convert the urea to ammonium (NH4+), which can evaporate as ammonia gas. Farmers can avoid significant nitrogen losses by not allowing UAN to remain on the soil surface for more than a few days.
