The recovery of fertilizer nitrogen by crops in the year of application is usually cited as being about 50%, despite considerable efforts to improve nitrogen efficiencies in agricultural systems. The use of fertilizer additives containing urease and/or nitrification inhibitors may improve fertilizer N efficiency. This was evaluated in four experiments conducted at multiple locations across the Canadian Prairies.
