Abstract

High-cost agricultural products have shown the needs for systems that increase productivity and promote improvements in the soil ́s physical and chemical qualities. A biological fertilizer at 0; 50; 100; 150; 300 L ha-1 was employed in a study conducted on the Cesumar Experimental Farm, in Maringá PR Brazil, to test the influence of increasing doses. The biological fertilizer was obtained from liquid compost with the addition of bovine manure, water and the commercial product Microgeo®, and the physical and chemical characteristics of the soil cultivated with rice (Oriza sativa) were determined. A totally randomized design, with four repetitions, was employed. Soil ́s chemical analysis was undertaken for each lot, the physical properties of soil were estimated from non deformed samples after harvest. Data were tested for normality and homogeneity and analyzed by analysis of variance and by Tukey ́s test at 5%. The application of biofertilizers affected the physical and chemical characteristics of the soil. However, further studies are required for thorough proof.
