BFD50 - BFD50: Field capacity 100 cm - OGC API Features

The soil overview map in scale 1:50.000 (BK50) provides an overview of the distribution of soil and soil-forming substrates for the entire area of Rhineland-Palatinate. The near-surface subsurface is depicted to a depth of two metres. Due to scale, the legend units of the soil map are composed of soil form societies (BFG), which are described via several use-differentiated soil forms (BF). The leading soil shape is the soil shape that has the largest area in a BFG. The field capacity (FK) refers to the amount of water that a naturally stored soil can retain against gravity. It also includes the so-called dead water, which is not usable for vegetation due to its high suction voltage (pF > 4.2).

比例尺为1:50000的土壤概图（BK50）可全面呈现莱茵兰-普法尔茨州全域内土壤及成土母质的分布情况，其展示了深度达2米的近地表亚表层地质特征。受比例尺限制，该土壤图的图例单元由土壤形态群（BFG）组成，而每一土壤形态群需通过多种按土地利用方式区分的土壤形态（BF）进行描述。某一土壤形态群中面积占比最大的土壤形态即为该群的优势土壤形态。田间持水量（FK）指自然储存状态下，土壤能够对抗重力留存的水量，其还包含因极高吸力值（pF＞4.2）而无法被植被利用的所谓无效水。
