Compostos orgânicos a base de resíduo de cervejaria como alternativa para o cultivo de hortaliças.

Abstract

Alternative substrates can contribute to the increase of macro and micronutrients, helping to improve the productivity of seedlings, reduce production costs, through the scarcity of natural resources, there is a growing demand for alternative compounds to be used for the cultivation of vegetables. The objective of this work was to evaluate the feasibility of applying organic compounds using brewery residues as alternative substrates, replacing industrial fertilizers and its influence on the chemical attributes of the soil. For the elaboration of the compounds, Pilsen type brewery waste was used. Therefore, it is concluded that the use of brewery residue in the proportions of 15% and 20%, presented a good absorption of nutrients by the vegetables. As for the feasibility analysis, it is possible to notice that there was a 5% reduction in the costs with compost, that is, with the modification of the control formulation by the proposed formulation, we can conclude with the results obtained that the brewery residue is a viable alternative of supplementation to the soil, without it affecting productivity.
