The impact on non-target arthropods of integrated compared to conventional farming: results from the LINK Integrated Farming Systems project.

Abstract

In the recently completed LINK Integrated Farming Systems project integrated and conventional farming were compared using split or quartered fields at six experimental sites across the UK and through a five-course rotation of cereals and break crops. Non-target arthropods were monitored as the main bio-indicator within the study. Numbers and diversity of non-target arthropods (Carabidae and Linyphiidae) differed most between the sites, years and crops and to the least extent between the two farming systems. Spring non-cereal crops and especially potatoes were the least favoured by Carabidae and Linyphiidae.
