Abstract
In soil some organic materials become encapsulated by clay resulting in the physical protection of organic matter from further microbial attack. Basic studies on protected organic matter pools will be conducted to provide an insight into the physical basis of their formation and breakdown. Protected pools of organic matter will be synthesised using a number of different organic matter nuclei to aggregate different clay types (1:1 and 2:1). The resulting microaggregates will be dried to selected water potentials with emphasis on water contents around the shrinkage limit. The formation of soil microaggregates and their resistance to mechanical breakdown will be evaluated to determine the significance of drying to aggregate stabilisation. We will also determine if dispersible clays are the primary mineral component of soil responsible for organic matter sequestration.
