In very small soil volumes we find very large numbers of micro-organisms. Yet, due to the complexity of the inner architecture of soil, very little of the total surface area is covered by microbes. What does this tell us about the function of soil microbes? And when we mix in roots, how does the soil-plant-microbe interface define the soil system in terms of its sustainability and future make-up?
This talk will focus on the interactions between soil architecture, soil microbes and soil water. It will seek to identify a new model, based on self organisation theory that seeks to explain the dynamics of soil biota interactions. It will present new data on soil architecture sourced from micro-tomography studies and introduce new models that account for soil processes in three dimensions.
