| description | Different methods of calculating soil losses by water erosion were compared with Soil Loss Tolerance in tropical Oxisols. The Potential Erosion Method and the Revised Universal Soil Loss Equation were used. The Potential Erosion Method was calculated by the Erosion and Flow Intensity software and an average soil loss of 1.46 Mg ha-1 year -1 with a maximum discharge of 649.31 Mg year-1 was obtained. Alternatively, an average soil loss of 1.52 Mg ha-1 year-1 with a maximum discharge of 668.26 Mg year-1 was obtained by the Universal Equation of Revised Soil Loss. Soil losses calculated by the two methods were similar and fell below the Soil Loss Tolerance limit, which ranged from 5.19 to 5.90 Mg ha-1 year-1 and validate the application of the Potential Erosion Method in Tropical soils of southern Minas Gerais State. |

Diferentes métodos de cálculo das perdas de solo por erosão hídrica foram comparados com a Tolerância de Perda de Solo em Latossolos tropicais. Foram utilizados o Método de Erosão Potencial e a Equação Universal de Perda de Solo Revisada. O Método de Erosão Potencial foi calculado no aplicativo Intensidade de Erosão e Escoamento e obteve uma média de perdas de solo de 1,46 Mg ha-1 ano-1 com descarga máxima de 649,31 Mg ano-1. Já pela Equação Universal de Perda de Solo Revisada, foi obtida uma média de perda de solo de 1,52 Mg ha-1 ano-1, com descarga máxima de 668,26 Mg ano-1. As perdas de solo calculadas pelos dois métodos foram similares e ficaram aquém do limite de Tolerância de Perda de Solo, que variou de 5,19 a 5,90 Mg ha-1 ano-1 e validam a aplicação do Método da Erosão Potencial em solos tropicais do sul de Minas Gerais. 2017-06-27 2022-03-17T15:14:32Z 2022-03-17T15:14:32Z info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion https://www.revistas.usp.br/rdg/article/view/132694 10.11606/rdg.v0ispe.132694 http://biblioteca-repositorio.clacso.edu.ar/handle/CLACSO/42241 por https://www.revistas.usp.br/rdg/article/view/132694/129861 Copyright (c) 2017 André Silva Tavares, Henrique Mendes Júnior, Velibor Spalevic, Ronaldo Luiz Mincato application/pdf Universidade de São Paulo.
