Abstract

Organic farming practices have recently been shown to benefit a wide range of above-ground taxa through increases in abundance and/or species richness. In relation to policy development, there is a parallel need to collate evidence on whether management practices that contribute to this effect above-ground (e.g. prohibition/reduced use of chemical pesticides and inorganic fertilizers) similarly effect below-ground biodiversity. Through a combined process of literature review and stakeholder interaction through expert groups this report addresses this issue but also considers the effects of below-ground biodiversity on the maintenance and enhancement of a range of ecosystem services.

Reported evidence suggests below-ground biodiversity benefits associated with reducing the intensity of use of mechanical and manufactured inputs in lowland systems. Evidence from hill and upland systems is insufficient to allow such conclusions. However, the evidence is not strong enough to draw conclusions about the effects of farming systems per se (e.g. organic versus integrated). This in part reflects the limitations of experimental design and the difficulties of transferring the results of reductionist research approaches to practical agriculture. This relates specifically to interactions between individual practices associated with producing a particular crop/crop sequence. Furthermore, it is clear that best practice is likely to be farm and even micro-site specific due to the complexity of interactions between soil organisms, soil type, weather and management factors. There is a critical need to address how current knowledge can be translated into guidance for land managers and policy makers.
