Policies to promote environmentally sustainable fertilizer use and supply to 2020 por Bumb, Balu L., Baanante, Carlos A.

“…In the early 1990s, however, fertilizer became a target of criticism mainly because of heavy use in the developed countries, where it was suspected of having an adverse impact on the environment through nitrate leaching, eutrophication, greenhouse gas emissions, and heavy metal uptakes by plants. Consequently, fertilizer use per se was mistakenly identified as an enemy of the environment. …”
