Inspire Download Service (predefined ATOM) for data set field capacity in rootable floor space

Description of INSPIRE Download Service (predefined Atom): The field capacity (FK) of a soil or the individual soil horizon is the amount of water that it can hold back against gravity after sufficient saturation (according to convention for suction voltage pF >= 1.8). It is expressed in mm and calculated for the respective width of a horizon, then added and classified to a depth of 100 cm or the rootable floor space (dB). The method represents the representative FK of the respective depth level. The link(s) for downloading the records is/are generated dynamically from a dataURL link of a WMS layerINSPIRE下载服务（预定义Atom格式）说明：土壤或单个土壤发生层的田间持水量（field capacity，FK），指其在充分饱和后（遵循吸力pF≥1.8的行业惯例）能够抵御重力而持留的水量。该指标以毫米（mm）为单位，先针对单个土层的相应厚度进行计算，随后进行累加，并按100厘米深度或可根域空间（dB）进行分级。该方法表征了对应深度层级的典型田间持水量。数据记录的下载链接将基于Web地图服务（Web Map Service，WMS）图层的dataURL链接动态生成。
