Physical-hydrical characterization in a dystrophic dusky-red latosol of Londrina, PR, Brazil

Abstract

The soil physical and hydrological properties of a dusky-red latosol dystrophic from Londrina, PR, Brazil (23º 23'S, 51º11'W), were evaluated. The following parameters were determined: granulometry, real density, bulk density, characteristic moisture curves, porosity, hydraulic conductivity, field capacity, available water, water storage capacity and infiltration. The data from characteristic moisture curves; hydraulic conductivity and infiltration were presented in figures and equations, contributing to facilitate the manipulation of experimental data.
