Student set Soil examination, TESS advanced Biology

Function and Applications

Case with material for 6 work groups to investigate the 18 most important soil parameters: soil profile (soil horizons, soil type), mineral matter (stone content, fine earth content, soil texture), body of humus (humus content, humus type), water/ air (soil moisture, water capacity, water permeability rate, utilisable water capacity), soil structure (soil compaction, aggregate stability/ tilth), acidity (pH value, lime content), nutrients (nitrate content of soil, nitrate content of fruit and vegetables), soil life (soil animals).

The set enables measurements of the following parameters to be carried out:

• Soil profile (depth, soil horizons, condition, type)
• Mineral content (stone content, fine soil content, soil type)
• Humus body (content and form)
• Water balance (soil moisture, water capacity)
• Permeability and soil structure (density, stability)
• Acidity (pH value, lime content)
• Soil nutrients (nitrate content)
• Soil life (soil fauna)

Benefits

• Easy to perform analyses using rapid test indicator sticks.
• Problem-oriented investigative methods to determine soil acidification, lime requirement, nitrogen supply, soil compaction, etc.
• The case can be used by 6 works groups working in tandem.
• Includes detailed instruction manual
