BFD50 – BFD50: Field capacity in rootable soil

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 state area of Rhineland-Palatinate. The near-surface subsoil is shown down to a depth of two meters. Due to the scale, the legend units of the soil map are composed of soil forming societies (BFG), which are described via several different uses-differentiated soil forms (BF). The guide floor form is the soil shape, which has the largest part of the area in a BFG. At the same time, its name forms the name of the BFG. The field capacity (FK) denotes the amount of water that a naturally stored soil can hold back 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).
