Pesticide Interactions with N source and Tillage: Effects on soil biota and ecosystem services

Research output: Contribution to conferencePosterResearch

Pesticide effects on soil biota must be interpreted in the context of the specific management practice, including rotation, fertilization, tillage, and pest control. Tillage, foe example, has been shown to reduce earthworm populations by up to 80%, depending on timing and specific tillage technique. Such disturbances may fully or partly obscure the effects of pesticides. The direct effects of pesticides and other management factors and their interactions must, therefore, be quantified before integrated pest management strategies that protect soil biodiversity and maintain soil functions can be identified. This study was planned to evaluate interactions between pesticide use and other soil management factors.

The study was carried out within a long-term tillage experiment using two tillage practices (no-till (NT) and mouldboard ploughing (MP), two contrasting N sources (manure and mineral fertiliser), and two pesticides (the fungicide mancozeb and the insecticide alpha-cypermethrin) in a split-plot design. Results on earthworms and microarthropods will be shown and discussed.
