The top three dishes contain the beetles collected from Pig Down at Lower Pertwood Farm
The lower dish has the beetles from a neighbouring 21 acre field where chemicals are used
During the drought of 2018, a comparative study was carried out to determine the population of
carabid beetles living in a 21 acre conventional field of winter wheat and an equivalent sized
field at Lower Pertwood Farm where no chemicals are ever applied.
The results came as no surprise. In the “conventionally-farmed” field, where chemicals had been
applied, the soil was dry, lifeless and most beetle larvae failed in these conditions. In the
organic fields, where the soil retained moisture and there was shading from weeds, more than
three times the number of beetles were counted. Why are they important? A bit like worms, they
carry organic matter deep into the soil to improve its quality to aid plant growth.
Alongside the beetle study, spiders were also counted and there were 70% more spiders in the
organic field, compared with the field where pesticides had been applied.
In our current times of climate change, the agro-chemical industry does not have all the answers.
Mother nature generally knows best.
