Abstract

This project will develop a combined theoretical and experimental approach of studying the effects on heterogeneity on competition between plants for below-ground resources. We will study the effects of heterogeneity on the capture of water, nitrate and phosphate at the scale of the rhizosphere, soil structural units, and whole plant, to identify the major causes of uncertainty in predicting the below-ground competitive ability of plants. We aim to incorporate the scale dependent effects of soil structure on transport into the root, study the effects of the root on the surrounding soil and on the soil-root interface, analyse the effects of the spatial distribution of roots in relation to the spatial distribution of soil resources, and apply uptake modelling to competition between root systems of two species in a heterogeneous environment.
