Methods/Characteristics Soil
Description
A method (in the Soil Science Specialised Information System) describes the prerequisites, application and outcome of a series of processing steps (linking rules) that derive aggregated statements from input data in the form of characteristic values or evaluations.
Characteristics (in the Soil Science Specialised Information System) are characteristic properties of soil research objects (soil type, soil type, base substrate, profile, etc.) which can be measured, calculated and expressed with a numerical value.
In the field of soil science, the Geological Service NRW mainly uses the following methods or determines characteristic values:
Evaluation methods for structural impairments
Potential risk of erosion of mineral soils by water
Potential compression sensitivity
Sludge inclination
Evaluation methods for water and substance balance
Filter properties of the soil versus heavy metals
Nitrate leaching hazard (exchange frequency)
Nitrate relocation depth in winter half-year
Plant-available soil water
Average annual leachate rate
Evaluation methods for location-based classification
Ecological humidity level
Natural soil fertility
Biotope development potential
Climate characteristic values
Current vapour pressure
Annual climate water balance
Potential evaporation (after Haude)
Interpolated day falls
Erodibility of precipitation
Characteristic values for the evaluation of filter properties
Nitrate leaching hazard (exchange frequency)
Hazard to groundwater by heavy metals
Geogenic heavy metal caps of looser and solid rock
