Infiltração de água e atributos físicos de um latossolo vermelho sob sistemas de manejo

Abstract

Management systems significantly influence the infiltration of water into the soil and may decrease or increase the rate of infiltration. The knowledge of the infiltration rate is of great importance, aiding in decision making for management and conservation of soil and water, and planning of irrigation projects, knowledge of the handling capacity of the water redistribution and management of soil conservation and water. This study aims to evaluate the effect of land use and soil management on the rate of water infiltration and its relation to the physical attributes of the soil. The infiltration tests were made by the method of concentric rings 15 points in each of the five management systems. Infiltration rates adjusted by Kostiakov model - Lewis ranged from, 216,5 mm h-1 for the SPC and 207,3 mm h-1 for the SPD, the areas with lower values of infiltration were, areas where grazing animals that received SILP-a 131,5 mm h-1, SILP-p with 87,9 mm h-1 and SPP had the lowest infiltration rate 70,0 mm h-1.
