Cross compliance soil erosion

Classification of agricultural land according to the degree of its erosion risk by water in accordance with the Direct Payments Obligations Ordinance in Rhineland-PalatinateIn the framework of the Direct Payments Obligations Ordinance, all agricultural parcels must be classified according to the degree of their erosion risk by 30 June 2010. As a subordinate authority of the Ministry of Economics, Transport, Agriculture and Viticulture, the State Office of Geology and Mining developed the necessary map bases.The calculation of the potential risk of erosion by water is carried out for Rhineland-Palatinate in a 20-metre grid based on the general soil degradation equation by multiplying the soil erosion, slope inclination and rain factor. The slope inclination factor is calculated from the digital elevation model (the steeper a slope, the greater the potential risk of erosion by water), the rain factor from the annual rainfall sums (the higher the precipitation, the more erosive the precipitation). The soil erodable keis factor for arable and grassland areas is derived from the class marks of the digital soil estimation data by assigning a K factor to each soil class combination (e.g. sL3Lö) (the more sludge, rocky, and humus-poor the topsoil, the greater the potential risk of erosion by water). From the grid data, the mean for each Rhineland-Palatinate parcel is calculated and no or the erosion hazard classes CCWasser1 (erosion hazard) or CCWasser2 (high erosion hazard) are assigned to it.
