Preferential Erosion of Soil Organic Carbon and Fine-Grained Soil Particles—An Analysis of 82 Rainfall Simulations

Soil erosion by water causes the loss of soil mineral particles and organic carbon (SOC). For determining effectiveness conservation measures on arable land, rainfall simulations are regularly carried out in field trials Czech Republic. The objective this study was to analyse a dataset from 82 bare fallow soils, containing information slope inclination, texture, bulk density, SOC, with respect preferential fine-grained enrichment SOC eroded soil. Each simulation comprised first period 30 min second one 15 duration. intensity 1 mm min?1 kinetic energy raindrops accounted for 8.78 J m?2 mm?1. Runoff samples were taken determine material. Regression analyses revealed that sites <14% mitigated period. On >14% driven Low generally coupled high vice versa, indicating occurred mainly soils low susceptibility. In order prevent maintain quality, important all types.
