A model predicted that the concentration profile of exudate would be less steep and its concentration values higher for larger diameter roots and that rhizosphere volume/g of root would be maximised at a particular root size for a given exudation rate. Root hairs, if active in secretion, would increase the rhizosphere volume/g of root and the substrate concentrations in it. Proteoid roots would increase the concentration of diffusing substance even further, although the rhizosphere volume per g of root may decline due to overlap effects. These effects are discussed in relation to the rate and extent of reactions between exudates and the soil.
