摘要：
Water erosion is a process that has a strong negative impact on soil and soil fertility. In addition to the large losses of fertile soil, as a result of the effects of water erosion, significant amounts of nutrients are lost and the soil quality of agricultural land is deteriorated. This work presents the results of six years of studies on the losses of mineral nitrogen and available phosphorus and potassium in the cultivation of wheat and maize on sloping terrains, on soil type calcium chernozem, due to water erosion processes. The impact of four different technologies (conventional and soil protective) on nutrient losses have been tested.
