Aplicação da vinhaça in natura e biodigerida no solo: efeito sobre a fertilidade e pH1.

Abstract

A great fleet of vehicle in Brazil is impelled by alcohol produced from sugar cane. Besides the alcohol , the process also results, a residue named vinasse. Due to the high D.B.O. (Dispute of Biological Oxygen), the vinasse shows high pollution when throw off in water courses. This procedure demands, therefore, effort to learn the possible ways of logical discard or the adequate utilization of the residue. The objective of this work was to evaluate the effects of the application of non-treated and biodigested vinasse. The application of non-treated, or biodigested vinasse, brought about changes in soil attributes.
