Contribuição do Resíduo da Produção de Farinha de Mandioca (Manipueira) para o Aumento da Concentração de Nutrientes no Solo

Abstract

The study evaluates the potential of the liquid residue (manipueira) generated in the production of cassava flour in the community of Cucurunã, Santarém-PA, as a source of nutrients for agriculture. The manipueira was physicochemically characterized, showing high levels of organic matter (BOD and COD), acidic pH, and the presence of cyanide. The results indicate that, with proper treatment, manipueira can be used as an organic fertilizer, contributing to the environmental and agricultural sustainability of the region.
