A Review on the Application of Sugar-Cane Organic Residue in Soil and Water Resources Management

Organic byproducts with the lowest content of heavy metals, without organic and industrial pollutants are as an alternative to mineral and organic fertilizers for agriculture. The final residue of sugarcane agro-industry (Vinasse) is among the residues that are produced in large amounts in Iran. Vinasse is rich in organic matter and can be considered for improving soil fertility and to reducing runoff and soil loss. Nonetheless, there has been less attention to determine the appropriate amount of Vinasse in soil and water resources management. According to the references, the amount of Vinasse more than 100 ton ha-1 will cause pollution of surface and groundwater. The aim of this paper is to review the use of the Vinasse and the appropriate amounts in soil and water resources management in available references and documents.
