土壤水分和养分资源的分布是不均匀的。植物根系必须科普和利用这种资源供应的异质性，以获得这两种关键资源。在这里，根系的反应，包括生根深度，根人口，形态和生理可塑性异质供应的水和养分将审查和讨论其生态后果。根系本身如何通过水力再分配过程影响水分分配，以及这一过程的生态后果，包括对养分供应的影响，也将进行研究。
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.
