Conteúdo: | The effects of six rates of applied wheat straw mulch on infiltration and erosion were studied on a highly permeable wea silt loam with 5% slope. Series of simulated rain storms totaling   6,25 inches at an intensity of 2.5 inches per hour were used to evaluate the treatments. Mulch  applications of 1,2 and 4 tons per acre maintained very high infiltration rates resulting in essentially no erosion. The 1/4 and 1/2 ton mulch application lost 3 tons and 1 ton of siol per acre, respectively, whereas the check (no mulch) treatment lost 12 tons per acre. Benefits which were indicated from the mulching were: 1) reduced soil surface sealing as evidenced by higher infiltration rates, and 2) decreased rainfall and runoff energy for particle detachment and transport asevidenced by reduced soil content in the runoff.
