Impact of diversified crop rotation on invertebrates - detailed studies
Project
Project code: REFORDAT-74, AZ II-1-F 41-2010.03
Contract period: 01.05.2010

Budget: 11,700 Euro
Purpose of research: Applied research
The significance of the agri-environmental measure „diversified crop rotation” on the protection of abiotic resources is well accepted. Positive results of this measure – especially on certain invertebrates - are predicted. However, substantial evaluation is difficult since only few studies have dealt with this topic so far. In 2009 we started studies on the diversity and abundance of phytophagous and carnivore invertebrates at reference farms in North Rhine- Westphalia. The aim of this study is to analyse the effects of diversified crop rotation on different trophic levels in contrast to farms practicing more simplified crop rotation. In 2010 more detailed studies on the abundance and diversity of ground beetles (Carabidae) and spiders (Araneida) will be conducted. Furthermore fitness parameters of ground beetles and spiders will be measured to characterize the health of the populations and the habitat quality. Furthermore the biomass of soil organism such as springtails (Collembola) and earthworms (Lumbricidae) will be quantified. The studies on solitary bees will be completed with pollen analysis to evaluate the study sites as foraging habitats. Based on the results of the studies we will derive suggestions for the evaluation and improvement of the agri-environmental measure “diversified crop rotation”.
