摘要：Water erosion is identified as the most severe type of soil degradation in the Czech Republic. Systematic protection preventing water erosion is not carried out in large areas of agricultural land. The map of the maximum tolerable CP factor value (the cover-management and the support-practice factors) – CP max was compiled in order to assess erosion hazard on agricultural land. It estimates the requirements of the conservation practices which would not cause soil erosion above the tolerable limit of annual soil loss. The map is based on calculations using an adjusted Universal Soil Loss Equation (USLE) and is easy to apply. It has already been applied in the Czech Republic when creating the map of erosion vulnerability for the purposes of delimitation of Standards of Good Agricultural and Environmental Conditions (GAECs), within Cross Compliance. The map covers the whole territory of the Czech Republic (scale 1:1,000,000).
