Abstract

We propose that soils with reduced microbial biodiversity (e.g. as a result of agricultural input) are significantly less resistant to perturbation than soils with a higher diversity. The purpose of this proposal is to establish a link between soil microbial diversity and soil resilience and also to develop a reliable assay for soil resilience. Our approach will be to measure a functional component of soil (in this case, decomposition of plant material which is a key process in the C cycle) which has been subjected to a transient or persistent stress and then to establish the kinetics of decomposition both before and after such stresses. The time taken for decomposition processes to revert to those prevailing at the outset will be taken as s a measure of soil resilience. The inclusion of a perturbation associated with the pollutant treatments at Sourhope makes the assay directly relevant to the pollution objection of the Soil Biodiversity Programme.
