Suction Variation of a Single Mature Tree on Top of Tropical Residual Soil

This paper investigates the suction variation induced by a single mature tree situated a top tropical residual soil, focusing on its impact on soil moisture content along a slope, where the tree's water uptake generates matric suction within the surrounding soil. A field monitoring program was...
