Estimation of erosion in earth roads of sugar cane using universal soil loss equation

Abstract

Soil erosion in earth roads of sugar cane is a problem that cannot be ignored, given the increase in planted area to this crop in Brazil. In this article soil losses are estimated using the Universal Soil Loss Equation (USLE), at four stretches of sugar cane earth roads of a farm at Itirapina (São Paulo State). Results showed that loss estimates ranged from 60.6 to 90.1 t.ha-1 for typic Quartzipsamment soil.
