Abstract
The distribution of water and nutrient resources in soil is heterogeneous. Plant roots have to cope with, and exploit, this heterogeneity in resource supply to acquire these two key resources. Here, the responses by roots including rooting depth, root demography, morphological and physiological plasticity to heterogeneous supplies of water and nutrients will be reviewed and their ecological consequences discussed. How roots themselves influence water distribution through the process of hydraulic redistribution and the ecological consequences of this process, including the impact on nutrient availability, will also be examined.
