What weather means for your nitrogen

Increasingly volatile weather conditions are changing how farmers handle their crop nutrients, including nitrogen (N), a key crop nutrient that is significantly affected by weather. As the weather patterns change, some farmers are losing more nitrogen from their fertilizers to the surrounding environment. In many cases, this is due to increased rainfall followed by long dry spells and warmer winters. With increased annual precipitation, more heavy rainfall events, higher temperatures and increased humidity, there is greater chance of losing nitrogen from leaching, volatilization and denitrification.

A 2015 study showed the planting season across the cornbelt was a struggle for many growers, with several thousand acres left unplanted due to all of the rain. Acres that were planted lost some of the nitrogen that was applied at/or before planting. Nitrogen losses can be as high as 40 per cent, but generally about 20 per cent, if urea is used incorrectly.

Growers who used ESN didn’t have to worry about when they applied their N or losing it to volatile weather conditions. ESN provides application flexibility, and can be applied over a range of times during the year and in a variety of weather conditions:

– Fall application – ESN won’t release into cold or frozen ground

– Wet conditions – ESN’s polymer coating helps stop leaching while inhibitors may be affected by excess moisture
