This project aims at defining possible effects of biological pollution on the soil, collating methods to record these effects and criteria to assess the suitability of these methods, developing a procedure to select effect-related methods for the risk assessment of natural and genetically modified organisms (GMOs), and defining the conditions under which a change represents a damage to the soil.
The project is subdivided into 4 modules:
Module 1 concentrates on the theoretical aspects, including work based on the evaluation of international strategies for the determination of soil quality, and includes an overview of the literature on GMOs and introduced organisms. It is conducted by Agroscope and FiBL.
Modules 2 and 3 put into practice the procedure drawn up for the selection of effect-related methods, both in a model experiment in the greenhouse and in a field trial. The model strain Pseudomonas fluorescens CHA0 is applied to wheat growing in pots (FiBL, Agroscope) and the bacterial product “Effective microorganisms” is applied in the field trial over a crop rotation sequence (Agroscope, FiBL).
Modul 4 syntheses the findings of modules 1 to 3.
