VINHAÇA THE USE OF THE CULTURE OF SUGAR CANE-OF-SUGAR

Abstract

The rational use of stillage as fertilizer for the sugarcane, is providing several benefits for units of production in Center-South and Northeast of Brazil. Besides to create conditions for an environmentally correct allocation of industrial waste, the fertigation improved agricultural income and spending with the economy generated by fertilizer. The practice is used by all the industries which have a technological and well defined knowledge, there are numerous tests that may confirm the positive results obtained in agricultural production associated with the economy of fertilizers. The great advantage of deploying the stillage is that it can replace some nutrients in large part of mineral fertilizer, a fact proven by numerous studies that show a increase in productivity of sugarcane due to its application. On another hand, the lack of more comprehensive studies that shows the effects of contaminants caused by high doses of application, lead us to recommend that the rates of application of stillage should be based on the need potassium and sulfur by the culture.
