dc.description.abstract | Abstract. Soil productivity, the intrinsic ability of land to yield useful products, can be affected by soil erosion. While much research has been carried out on the processes, there is as yet little information on the impact of soil erosion on in situ productivity of agricultural land in the British Isles. This paper reports the results of a de‐surfacing experiment on deep sandy soils in East Anglia. Grain yields of fertilized barley planted immediately after de‐surfacing were at least 15 and 45% less on 15 and 25 cm de‐surfaced plots than on non‐desurfaced soils. There was strong evidence pointing to an acceleration of soil erosion itself on the de‐surfaced plots. Both the amount of water stored in the topsoil and water use by the crop decreased with increasing severity of simulated erosion. We observed a drop in organic matter and readily available nitrogen with erosion. Nitrogen mineralization and leaching losses were also affected by simulated soil erosion. The experiment showed that sudden severe erosion may induce substantial barley production losses on deep sandy soils. The size and effect of de‐surfacing depends on a number of factors such as soil depth, subsoil type, precipitation and crop type. Copyright © 1995, Wiley Blackwell. All rights reserved | en |
