Farmers depend on nitrogen for maximum crop yields, but admit it's the most difficult nutrient to manage. This is due, in part, to the volatility of urea and urea-containing fertilizers, which can lose up to 30 percent or more of their nitrogen if not incorporated by rainfall or tillage within 72 hours. It makes urea or urea-containing fertilizers sound choices for any type of surface application.
Farmers now have a longer window of opportunity.
