Resumo

This work aimed to evaluate the application of several doses of two sources of organic material in the physical-chemical properties of two soils of the ‘Vale do Caí’ region. The experiment was carried out using clayish and sandy soils. Four treatments were tested: organic compost with the doses of zero (control; T0), 40 Mg?ha-1 (T1), and 80 Mg?ha-1 (T2); and a treatment using an industrialized humic substance at the dose of 50 Mg?ha-1 (T3). The physical properties of total porosity, macro and micropores, and water retention capacity were evaluated; the chemical properties of pH and electrical conductivity were also evaluated. The results showed that the addition of 80 Mg?ha-1 (T2) of OM increased the total porosity, and the quantity of macro and micropores in the sandy soil, not affecting the clayish soil. The treatment using the industrialized humic substance (T3) reduced the total porosity of the sandy soil. The CE and pH values increased with the dose of organic material, with exception of the industrialized source (T3), which has not differed from the control (T0).
