USO DO GESSO MINERAL EM LATOSSSOLO CULTIVADO COM CANA DE AÇÚCAR

Abstract

Aluminium contents in soils from the sugar cane plantation áreas of Pernambuco estate Brazil, are often phytotoxic, specially em subsurfeces. Mineral gypsum has gained growing interest for supplying Ca and demosshing Al saturation, therefore enchancing the root system development. The work was carried out to evaluate the efectts of mineral gypsum applied to on oxisol. The treatments compused five doses of gypsum of two granulometice fraction. For both fractions, gypsum reduced the Al saturation in all the soil. On the other hand, the coarse gypsum was more effective than the fine gypsum one the Al saturation.
