A raging debate is underway on why and to what extent excessive nitrogen fertilizer use is degraded soil quality around the world. The problem is unmistakable in many countries as average crop yield levels plateau or even start of decline.
Three University of Illinois scientists explain why in a compelling commentary. The two published papers by this team from 2007 and 2009 are the first and second most read papers in the prestigious "Journal of Environmental Quality."
Thanks to the team for permission to post this important piece.
