BFD50 - BFD50: usable field capacity in rootable soil

The 1:50,000 scale soil overview map (BK50) provides an overview of the distribution of soils and soil-forming substrates for the entire state area of Rhineland-Palatinate. The subsurface is depicted to a depth of two meters. On a scale basis, 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 share in a BFG. Its name is also the name of the BFG. <a href='https://www.lgb-rlp.de/service/lgb-downloads/boden-d.html #c1937' target='_blank'>Documentation of methods</a>:The usable field capacity of a soil is the part of the field capacity available for vegetation. It contains the amount of water that a site away from groundwater can retain in natural storage after sufficient saturation against gravity and corresponds to a suction voltage of pF 1.8 to 4.2 according to convention.
