Characteristics of the soil overview
Description
The legend units of the soil overview map 1:200.000 and these standard profiles accompanying content characterisation form the basis for the derivation of characteristic values to site properties (potential cation exchange capacity), water movement (saturated water conductivity) and water binding (field capacity, usable field capacity, air capacity). A derivation of the soil type-specific characteristic values is carried out in accordance with the soil history mapping instructions, 5th edition, Part B, pp. 342 – 372.
— Floor type of the topsoil describes the typical type of soil of the topsoil on the basis of the profile descriptions of standard profiles in the nomenclature of the flooring guide (KA5), p. 141ff, Fig. 17 and Table 30. Soil types are distinguished according to the grain size composition of their mineral stock.
— Field capacity of the soil up to 100 cm profile depth is the amount of soil water in volume % or mm of water column that it can bind at a suction voltage pF >= 1.8 or in pores with an equivalent diameter <= 50 µm. The classification is carried out according to KA5, p. 349, tab 74.
— Usable field capacity of the soil up to 100 cm profile depth is the amount of soil water in volume % or mm of water column that it can bind at a defined suction voltage between pF = 1.8 and pF = 4.2 or in pores with an equivalent diameter between 50 µm and 0.2 µm. The classification is carried out according to KA5, p. 349, tab 74.
— Floor air capacity up to 100 cm profile depth is the pore space that is filled with air at field capacity with a defined suction voltage of pF > 1.8. It is a measure of oxygen supply to plant roots. The classification is carried out according to KA5, p. 349, tab 74.
— Saturated water conductivity of the soil up to 100 cm profile depth is a measure of the permeability of a water-saturated soil. The classification is according to KA5, p. 355, tab 80.
— Potential cation exchange capacity of the soil up to 100 cm profile depth represents the amount of interchangeably bound cations at the sorption complex at a pH of 8.2. The classification is carried out according to KA5, p. 362, tab 85.
