You might think that when nitrogen fertilizer is in the ground, it's safe. New research suggests you need to think again. When shallow banding unprotected urea less than two inches deep, researchers found that nitrogen loss due to ammonia volatilization can be even greater than unprotected broadcast urea.

Research by Agriculture and Agri-Food Canada showed that when untreated urea was placed in bands two inches below the surface, nitrogen loss due to ammonia volatilization was more than 25% (Figure 1). Additional moisture below the soil caused the incorporated urea to dissolve and hydrolyze quicker, releasing more ammonia gas.

Lost nitrogen can have an impact on your yield and return on investment. Research conducted on canola at sites across Alberta, Saskatchewan and Manitoba showed that protecting shallow-banded urea with AGROTAIN™ nitrogen stabilizer resulted in a 5 bu/acre average yield advantage compared to shallow-banded unprotected urea (Figure 2).

AGROTAIN DRI-MAXX stabilizer is proven to control nitrogen loss from volatilization, ensuring that your nitrogen investment remains readily available for plant uptake. Protect your nitrogen investment, yield potential and return on investment with AGROTAIN DRI-MAXX nitrogen stabilizer today.
