Tenuta is the senior industrial research chair in 4R nutrient management and professor of soil ecology at the University of Manitoba,… Read More
Once nitrogen fertilizer lands on or in soil it may be at risk of loss — through leaching, volatilization, or denitrification. Management choices can minimize losses, through split-application, deep banding, or choice of product, but adding an enhanced efficiency fertilizer product can guard against loss, too. How the products work, when to use which, and… Read More
