Fertigation with vinasse in São Roque do Canaan-Es

Abstract

The production of "cachaça" from sugar cane has become an economically important activity in recent decades due to the increased demand from internal and external consumption, as a result, generating high levels of input, such as filter cake and stillage. In this study, we investigated the influence of vinasse addition to sugar cane cultivated soils by determining the levels of micro and macronutrients present in the soil and of sugar present in sugar cane juice at the Sereia distillery in the city of São Roque do Canaã, ES, Brazil. The findings of this study indicated that fertirrigation with vinasse has not altered the soil's organic matter significantly. An increase was also found in sugarcane micro and macronutrient contents, total and reducing sugar, and in the moisture of the stems corroborating data reported in the literature.
