Conservation techniques are highly relevant, for sustainable land use, especially in semiarid regions. The aim of this study was to investigate the impact of conservation techniques in reducing sediment losses and increasing soil moisture, under natural rainfall in soil erosion plots. The study was carried out in the Alto Ipanema River Basin, Brazil. The experimental monitoring was carried out in nine plots with different cover conditions (bare soil; natural cover; mulch; Forrage Palm Cactus). Mulch presented similar performance than natural vegetation cover, to control runoff and sediment losses. Soil moisture was signifi cantly higher in plots with mulch when compared with in those with bare soil. Additionally, Palma lines produced promising hydrological results. Complementary experiments in the laboratory, with simulated rainfall, were consistent with field observations under natural events.
