Estimativa de perdas de solo por erosão hídrica para a região missioneira do Rio Grande do Sul

Abstract

Water maintenance is currently a worldwide problem, which is causing soil loss. This process can bring several environmental resources, among them, a natural resource necessary for the survival of human beings. And every form of life that dwells in it. However, availability is directly related to handling by the animals. This study was used in the Universal Soil Loss Equation (EUPS), thus, verifying if these species are within the maximum tolerable limit for the region under study. It was evaluated as soil losses through the creation of different management scenarios, with presence or conservation practices in soil representative of the RS mission region. Based on data on estimated soil losses in scientific works in the region, in order to estimate the moment when these losses are above the tolerable limit. It can be said that, with the use of the conventional maximum, they can reach the maximum planting in all planting scenarios, when using no-tillage combined with complementary practices, it does not reach the limit of Latosol Vermelho losses. The use, grateful and that will be very important for the preservation of the soil.
