Product: Soil

Soil is one of the most important parts of the landscape and therefore prominent in the resource-protection and resource-using - especially in problems of buffer the pollutants like heavy metal, nitrate, …, problems of water-producing (see: evaporation, recharge of ground water, …), of the agricultural yield potential (soil erosion, "precision farming", …).

The aspects mentioned above need manifold area information regarding the geo-factor "soil". Normally the information is taken out of soil maps but there may be no soil maps of the area you are interested in or the spatial resolution of the given soil map is insufficient or you need further information than is contained in the conventional soil maps.

To help with these problems the scilands GmbH and associates are developing "functional soil maps".

Advantages (of our product: Soil):

• Regionalisation of a high amount of useful soil characteristics
  instead of complex genetical oriented soil maps you get a purposeful data base to handle specifics as soil erosion risk assessment or recharge of ground water.
  
• To value the available data
  We value the "basic data" to minimise the expenses of doing field work.
  
• Regionalising soil characteristics as a continuum
  Because the soil characteristics vary with smooth transitions we model the soil characteristics as a continuum represented by metric grid data. (Whereas conventional soil maps work with boundaries.) The specific (application) classification (for the user) will be the result. usually conventional maps prematurely classify the soil-relevant geo-factors and therefore are often inexact.
• Inductive methods
  In contrast to conventional soil maps being deductive and therefore mostly subjective our soil regionalisation is highly inductive because of the quantative application as explained above.
  
  

Our product " Soil" subdivide as follows:

• Functional soil maps
  practicable interpretation for specific questions
  
• Soil maps concerning ground water
  Regionalisation of soil water balance (surface flow, ground humidity (soil moisture), recharge of ground water)
  
• Soil maps concerning soil erosion
  Regionalisation of soil erosion risk assessment
  
• Soil maps concerning filter-quality of the ground
  Estimation of the endanger of nitrate washing-out
• Soil maps concerning the soil physics, e.g. soil texture
  Regionalisation of granulometric composition, to estimate the water permeability and the rooting dephts
  
• Soil maps concerning soil chemistry
  Estimation of cation exchange capacity
