INSPIRE Download Service (predefined ATOM) for dataset usable field capacity in 1. metre

Description of the INSPIRE Download Service (predefined Atom): The usable field capacity (nFK) of a soil or horizon is the part of the field capacity available for vegetation. It thus contains the amount of water that a horizon far from groundwater can retain against gravity in natural storage at suction voltages of pF 1.8-4.2 after sufficient saturation. The calculation is initially made for each horizon. The results are added up and classified to a depth of 100 cm or the rootable soil space (dB). The method reproduces the representative NFC of the respective depth level. - The link(s) for downloading the records is/are dynamically generated from a DataURL link of a WMS layerINSPIRE下载服务（预定义Atom格式）描述：有效田间持水量（usable field capacity, nFK）指土壤或发生层中可供植被利用的田间持水量组分。该参数代表经充分饱和后，远离地下水的发生层在自然储水条件下，于pF值1.8至4.2的吸力势下可对抗重力留存的水量。计算初始以单个发生层为单位开展，随后将各层结果累加，并以100厘米深度或可根系生长的土壤空间（rootable soil space, dB）为基准进行分级。该方法可复现对应深度层级的代表性有效田间持水量。—— 数据集记录的下载链接由Web地图服务（Web Map Service, WMS）图层的DataURL链接动态生成。
