Hydraulic redistribution is a phenomenon in which water moves through plant roots from wet soil layers to drier soil layers within the root zone. This process helps to redistribute water more evenly throughout the soil profile, benefiting neighboring plants and soil microorganisms. Hydraulic redistribution is important for improving plant water use efficiency, especially in arid and semi-arid environments where water availability is limited. Research in this area focuses on understanding the mechanisms and ecological implications of hydraulic redistribution, as well as its potential role in mitigating the effects of drought and climate change on plant communities.
