Abstract


The experiment was developed in the Laboratory of Soils of the University Campus of Alta Floresta, which belongs to the UNEMAT - Universidade do Estado de Mato Grosso (State University of Mato Grosso). The compounds used in the formula of the substrates tested were obtained in the municipality of Alta Floresta – northernmost of the state of Mato Grosso. The aim of this study was to evaluate the physical characteristics of different organic substrates formulated with organic waste for production of forest seedlings in tubes. We tested twelve substrate combinations (treatments). The analyzed characteristics were: density, total porosity, micro and porosity and capacity to retain water in tubes of 50 cm3. T6 (70% of cattle manure and 30% rice hulls) was the substrate that showed the best values for the analyzed parameters, and it can be tested for seedling production.
