SUSTENTABILIDADE NO USO DO FÓSFORO: UMA QUESTÃO DE SEGURANÇA HÍDRICA E ALIMENTAR

The phosphorus used as fertilizer in agriculture is extracted from phosphate rocks, which after extraction reacts with sulfuric acid, releasing phosphoric acid, a raw material for the fertilizer industry. Studies point to a possible depletion of world reserves of phosphate rock in the next 50-100 years. A phosphorus scarcity is closely linked to global food security, given the dependence of soil fertilization to maintaining agricultural productivity within the current patterns of agribusiness. The application of fertilizers in soil and the sanitary sewers have been historically responsible for...
