Grass strip effects on runoff and soil loss
WebSoil loss from the field was reduced by 65% and 70% downstream of the 2 m grass strips on the upper and lower slopes for the four observation seasons ( Figure 2 ). Soil loss … WebThe soil loss from this one event was 22 tonnes per hectare. Treatments A and B with higher cover levels had much less runoff, soil and nutrient loss. It can take thousands of years to form an inch of soil. The depth of soil lost from treatment C from this one storm event may take hundreds of years to replace, provided no further erosion occurs.

WebThe effects of grass strips on runoff interception, sediment trapping and soil loss were studied during two agricultural seasons. Field studies, conducted on loamy soil susceptible to sealing, allowed the comparison of three situations corresponding to buffer strip widths of 0, 3 and 6 m located at the downslope end of a winter wheat field. WebMar 2, 2024 · The erosion effect of confluence on a sloping farmland is increased during summer and autumn due to the frequent occurrence of high-intensity rainfall in the black soil area of Northeast China,coupled with its special length and gentle slope topography (An et al., 2012; Wen et al., 2015).The high frequency of instantaneous rainfall intensity of ...
WebRiparian buffers have been used more commonly than grass hedges to control water erosion. These buffers not only slow runoff flow and filter sediment but also can improve wildlife habitat and diversity and provide numerous additional ecosystem services. Riparian buffers can reduce runoff and sediment transport by at least 30% (Sheridan et al., 1999 WebVegetation plays a significant role in controlling soil erosion. However, the effects of each vegetation type on soil erosion have not been fully investigated. In order to explore the influence of multiple vegetation covers on soil erosion and surface runoff generation, 10 different vegetation types, typical of the Nverzhai small basin, have been selected for this …
WebTable 3 summarizes the results of simulations of the effects of various erosion control practices on soil and nutrient losses compared to a tillage system typically used in the Corn Belt. WEPP (Laflen et al., 1997) was used to calculate runoff and soil loss for all tillage systems and to calculate enrichment ratios for sediment. Web3.1 Runoff process. The runoff rates under different grass strip patterns and inflow rate patterns are shown in Fig. 5.With lengthened duration, the runoff rate shows an increasing trend in the initial stage, then fluctuates, and finally tends to stabilize (Fig. 5 a). The change trend of the runoff rate with inflow rate is clear; i.e., it increases with increasing inflow …
WebSince the runoff generation and consequently, soil erosion depends on soil conditions, the time when the ERs occur can play a role (Q. Wang et al., 2024a). Fig. 8 a shows that the top four rainy day in baseline scenario which happen in spring and summer (two in March, June, and August) and values for all four days increases as CI grows (S0 to S3).
WebJul 18, 2024 · They indicated that a grass strip can remove the runoff volume by 40%, suspended solids by 87%, total phosphorous by 64% and nitrate up to about 33%, while the grass–tree strips reduced the runoff volume by 35%, suspended solids by 85%, total phosphorous by 85% and nitrate up to about 30%. ...
