Estimativa das perdas de solo por erosão hídrica utilizando o Método de Erosão Potencial

Abstract: A erosão hídrica é a principal forma de degradação dos solos tropicais, gerando inúmeros prejuízos ambientais e socioeconômicos. As estimativas das taxas de perdas de solo por erosão hídrica são importantes para avaliar a degradação do solo e para proposição de medidas de manejo conservacionistas. Dentre os diversos modelos, o Método de Erosão Potencial se destaca pela facilidade de aplicação e baixo custo de implementação para estimar as taxas de perdas de solo. Dessa forma, o objetivo do trabalho foi aplicar… Show more

“…In this method, the Latossolo was the soil class that obtained the highest value, which can be explained by adding permeability, agreeing with the results of Oliveira et al (2008). According to Pinto et al (2020), Latossolos, due to their high permeability, high effective depth, and low textural ratio, associated with the predominance of medium/clayey texture, welldeveloped structure, and considerable organic matter content, contribute to their greater resistance to water erosion. ------------------------t ha -1 year -1 ------------------- (Bertol and Almeida, 2000); Method III (Galindo and Margolis 1989).…”

“…The sub basin is located at the urban perimeter of the Alfenas Municipality, southern Minas Gerais State, South-eastern Brazil. The geological framework is constituted by garnet-biotite-gneisses and biotite gneisses with quaternary soil covers, with fluvial deposits of gravel, sand, and clay (Pinto et al, 2020). The soils are mainly composed of Latosols and Indiscriminate Floodplain Soils (Marangon et al, 2017).…”

“…Os problemas resultantes da erosão dos solos podem ser: remoção de nutrientes, redução da penetração das raízes e consequente armazenamento de água, diminuição das áreas agricultáveis e de pecuária, assoreamento de corpos hídricos, enchentes ao elevar o pico de vazão de rios e poluição dos corpos hídricos, em especial devido ao transporte de agroquímicos junto à sedimentos erodidos (GUO et al, 2019). Certas regiões da BHRP, mais especificamente em sua região oeste, possuem solos mais suscetíveis à _________________________________________________________________________________________________ erosão hídrica, sendo esta a principal forma de erosão responsável pela degradação de solos tropicais (SANTOS; SCUDELARI, 2011;PINTO et al, 2020).…”
