Validating and Improving Interrill Erosion Equations
Existing interrill erosion equations based on mini-plot experiments have largely ignored the effects of slope length and plot size on interrill erosion rate. This paper describes a series of simulated rainfall experiments which were conducted according to a randomized factorial design for five slope lengths (0.4, 0.8, 1.2, 1.6, and 2 m) at a width of 0.4 m, five slope gradients (17%, 27%, 36%, ...
متن کاملRunoff and Interrill Erosion in Sodic Soils Treated with Dry PAM and Phosphogypsum
Seal formation at the soil surface during rainstorms reduces rain infiltration and leads to runoff and erosion. An increase in soil sodicity increases soil susceptibility to crusting, runoff, and erosion. Surface application of dissolved polyacrylamide (PAM) mixed with gypsum was found to be very effective in decreasing seal formation, runoff, and erosion. The objective of this study was to inv...
متن کاملInfiltration and interrill erosion responses to selected live- stock grazing strategies, Edwards Plateau, Texas
Understanding tbe temporal response of infiltration rate and interrill erosion to selected livestock grazing strategies is necessary for the continued soil and water conservation of rangeland. Inflltration rate and btterrill erosion were sampled bimontbly from 1978-1984 on pastures grazed continuously (MCG) and moderately stocked (8.1 be AU-r); continuously (I-ICC) and heavily stocked (4.6 ha A...
متن کاملTemporal Variation of SOC Enrichment from Interrill Erosion over Prolonged Rainfall Simulations
Sediment generated by interrill erosion is commonly assumed to be enriched in soil organic carbon (SOC) compared to the source soil. However, the reported SOC enrichment ratios (ERSOC) vary widely. It is also noteworthy that most studies reported that the ERSOC is greater than unity, while conservation of mass dictates that the ERSOC of sediment must be balanced over time by a decline of SOC in...
