Study directors with many years of experience, breeding test animals at a high level, modern test technology
and highly efficient project logistics constitute the solid basis for a wide range of located-based testing capacities.
Our modern climatic test rooms and our spacious greenhouse offer ideal preconditions
for the execution of all relevant studies on soil organisms in compliance with OECD / ISO / EPA.

Laboratory studies
• Eisenia fetida / Eisenia andrei – acute toxicity (OECD 207)
• Eisenia fetida / Eisenia andrei – reproduction (OECD 222)
• Oligochaetes     – bioaccumulation (OECD 317)
• Folsomia candida – reproduction (OECD 232)
• Hypoaspis aculeifer
– reproduction, mortality (OECD 226)
• Enchytraeid – reproduction (OECD 220)
• Soil microflora test – nitrogen transformation (OECD 216)
• Soil microflora test  – carbon transformation (OECD 217)

Greenhouse studies
Study directors with many years of experience, modern greenhouses and the corresponding
test technology constitute the solid basis for a wide range of location-based testing capacities in this area.
The most recent and standardized guidelines provide a solid basis
for the implementation of the tests (OECD 227, OECD 208, BBA 29).

Field studies
• Earthworm studies
    – available in many different regions and for a large variety of crops
    – sampling by means of hand-sorting and formalin extraction
    – determination of determining the earthworm population, including the range of species
