Coupled Behaviour of Soil and Plant Water Dynamics: Effects of Vegetation Cover, Soil Type and Fire Disturbance
Plant and soil water dynamics are crucial for terrestrial carbon uptake, agriculture and human livelihoods. As plants primarily rely on water uptake from the soil, soil and plant water dynamics are strongly coupled over most of the land surface. Soil and plant water dynamics also play a crucial …
