RECICLAGEM DE LODO INDUSTRIAL, CLASSE II, COMO SUBSTRATO PARA PRODUÇÃO DE MUDAS

Abstract

The industrial sludge is a residue with great concentration of organic substance and needs the establishment of techniques for correct insurance recycling. Agriculture has been the option more chosen by the industry for final disposal of this residue being necessary to evaluate new options for this purpose. An experiment with intention of evaluate the potential of the use of industrial sludge for development of changes was lead. In this direction it was established increasing doses of the residue (5, 10, 20 and 40%) that they had been mixed to a commercial substrat. The material then was evaluated for the production of changes of tomato, eggplant and lettuce in greenhouse. The joined results had demonstrated that the silt in the biggest doses affects the emergency of the plants more sensible as the lettuce. The concentration of 10 % of industrial sludge provided the best development of the cultures, comparative with the pure standard substrat. It can be concluded then that the silt presents potential for exploitation in this segment of agriculture, mainly for less sensible cultures to germination.
