GESSO MINERAL COMO FONTE DE ENXOFRE PARA CANA-DE-AÇÚCAR

Abstract

The goal of this work was to evaluate the sulfur supply in soils of different textural classes using the mineral plaster originating of the region of Araripe-PE as sulfur source the sugar cane. They were installed 5 field rehearsals in different classes texturais soils to evaluate the effects of the mineral gypsum as sulfur source in the sugar cane plants nutrition. It searched the relations of the sulfur in plant, evaluating itself your availability. The rehearsals were led in the Zone of the Woods of Pernambuco. The experimental delineation employee was the one of blocks at random. The treatments in each rehearsal they constituted of the combination of 5 sulfur doses, with 3 repetitions (5 x 3). They evaluated the treatments at 16 months after the application of the sulfur doses calculated by the exchangeable aluminum neutralization and or calcium exchangeable content method, for the 0,4-0,6m soil depth layer. In the loamier soils and of smaller values of P-rem the sulfur doses promoted sugar cane larger production. The sulfur doses were enough for the sulfur supply for the sugar cane.
