CSA News 11 A lthough nitrogen fertilizer is the “critical ingredient” sustaining most modern crop production, it can have significant downsides as well. Nitrate nitrogen lost from the crop root zone through leaching is not only a substantial economic loss to producers, but also an environmental concern when the leached nitrate enters rivers and lakes and a health risk when the nitrate enters wells and aquifers used for drinking water. Hence, researchers have been working for decades to develop effective strategies for keeping nitrogen fertilizers in the root zone and available for crop assimilation.
