The recent increase in fertilizer costs, especially nitrogen fertilizers, has resulted in technologies that may improve nitrogen use efficiencies in agronomic cropping systems. Many of these technologies are designed as fertilizer additives to increase fertilizer use efficiencies by increasing plant fertilizer uptake and crop yields. The resulting fertilizer formulations include some type of extra additive within the formulation or applied as a coating and are often referred to as “enhanced efficiency fertilizers” (EEFs).
