Abstract
To examine the hypothesis that soil organic matter and micro-organisms are stabilised within the soil microaggregates, so that the main sites of organic matter mineralisation and the more rapidly changing microbial populations are associated with the macroaggregates. The distribution of soil micro-organisms associated with the aggregates, including the different distributions of two distinctly genetically marked Rhizobium, will be determined. The work is designed to provide criteria to decide if other introduced micro-organisms can affect soil processes such as organic matter mineralisation or the distribution of native soil organisms.
