Wind erosion is a serious hazard in many areas of Europe, it reduces production, causes pollution and jeopardises sustainable agriculture. However, there is a dearth of quantitative evidence for the problems of wind erosion. The study site is in an agricultural area where many contemporary cultivated fields are bounded by accumulations of soil indicative of historical wind erosion. One field and an adjacent boundary accumulation were investigated to establish whether soil physical and chemical properties could be used to reconstruct the wind erosion history of the field and to examine the impact of wind erosion on the soil nutrient status. Soil physical and chemical properties identified original soil beneath an aeolian accumulation in the field boundary. Nitrogen was the only soil nutrient found to be depleted in the field relative to the aeolian accumulation. Preferential selection of the small nutrient-rich particles and organic matter by wind erosion was responsible for this depletion. The control of wind erosion would appear to be as important to sustainable crop production as the frequent application of fertiliser.(Download PDF) (Export to EndNotes)
