Soil organisms

There are many organisms living on and in the soil that form a complex ecosystem. They contribute to formation of the soil and provision of nutrients and influence its structure and ventilation. It is also in the particular interest of us humans that plant protection agents should not harm the creatures living in the soil. Healthy soil is the basis for production of foods and regrowing raw materials.

Our Service

Experienced test managers, test animals from own breeding, modern test technology and effective project logistics form the basis for comprehensive test capacities. Open-field studies can be conducted in various sites with a variety of crops and the option of sprinkling them. Our state-of-the-art climate test rooms, the generous greenhouse and internal soil and residue analytics offer the ideal prerequisites for performing all relevant studies on soil organisms according to OECD/ISO/EPA.
