Resumo: | Considering the need for viable options for destination of waste from agricultural and agriindustries activities waste from logging and brewing industries and goat dregs previously composted, with potential foruse as substrates for the production of seedlings of trees were characterized chemically and physically. The treatments had consisted of the following mixtures: S1) commercial product for substratum (Plantmax® Florestal) + pinus bark partially decomposed - PB (1:1); S2) residue of malt with wooden sawdust - WS (1:4); S3) cellulosicmud with WS (1:1); S4) mixture of treatment S3 product with PB (1:1); S5) black-liquor with WS (4:1); S6) blackliquor with WS (3:2); S7) mixture of the product of treatment 6 with PB (1:1); S8) goat dregs. The following variable were evaluated: pH CaCl2; P, C, N, K, Ca, Mg, Al, H+Al and Na concentrations; CEC, Al saturation and C/N; total porosity, macroporosity, microporosity, density and available water. The substrates made with mixtures of Plantmax Florestal® + PB (1:1); residue of malt with wooden sawdust - WS (1:4); cellulosic mud with WS (1:1) mixed with PB (1:1) and goat dreg composted can be used in the production of seedlings of forest species tolerant to acidity, adopting the protocols of management recommended, both for irrigation as for fertilization.
