Erodibility factor of four soils from the municipality of São Mamede, Paraíba State, Brazil

Abstract

The purpose of this work was to determine the erodibility of four representative soils from the municipality of São Mamede, Paraíba State, Brazil. Based on some physical properties, the K values, i.e. the erodibilities were determined by using the universal soil loss equation (Wischmeier nomogram). The Vertic Non-calcic brown and Non-calcic brown are more sensitive to erosion. with K values from 0.29. The Podzol and Lithosol soil exhibit values from 0.26 and 0.18 respectively.
