Atributos físicos de um latossolo vermelho da área experimental da Universidade Federal da Fronteira Sul - Campus Erechim

Abstract

Soil is a natural living resource and dynamic critical to ecosystem functioning and represents a balance between the physical, chemical and biological factors. In this sense the physical properties are considered indicators of soil quality, as they make possible see if there was deterioration or improvement in soil physical quality in order to be able to guide their use and management. Thus, this study aimed to characterize and describe the physical attributes such as texture, particle density, bulk density and water infiltration into the soil of an Oxisol in the experimental area of the Federal University of the Border South- Campus Erechim, RS, under different systems management. These areas disturbed samples were collected for determination of texture and density of the particles. The texture was determined by sieve analysis, and the density of the particles by the method volumetric flask. Undisturbed soil samples to determine soil density. The porosity of the soil was determined with the ratio of the densities. The infiltration was determined with the use of concentric cylinders. The management system with conventional tillage
