Análise do potencial de utilização de resíduos agroindustriais na produção de biofertilizantes

Abstract

Agribusiness in Brazil has become increasingly the basis of the economy. With a large production, there is, consequently, a high generation of waste, which if not reused correctly, will significantly lose its economic value. Vermicomposting is an alternative for reuse for these organic residues and aims to produce a compound of high added and nutritional value: earthworm humus that can be used as an alternative to conventional chemistry fertilizer. The diversity of residues that can be used in the technique result in variations in the chemical composition of the substrate, so the present work was focused on the vermicomposting of residues such as coffee straw, shell of peanuts and bovine manure. For this evaluation, both dry and liquid vermicompost were used, and therefore, analyses of moisture content, total solids, volatile solids, soluble solids, organic and inorganic contents will be performed to assess their potential as agricultural biofertilizer.
