![]() ![]() ( 2011) demonstrated that contrary to the usual assumption of higher depletion in vicinity of roots (Gardner 1960), soil water content is higher in rhizosphere soil compared to bulk soil over a wide range of pressure heads, indicating a significant change of the water retention curve in vicinity of plant roots. Roots are a key element in plant related effects on soil structure and soil hydrology (Gregory 2006 Bengough 2012 Logsdon 2013). Among the various driving factors of soil structural porosity, vegetation is playing a dominant role. retention and hydraulic conductivity, in the saturated and near-saturated range (Cresswell et al. Beside texture, soil structure is the main property to shape the fundamental relations for soil water flow, i.e. Soil hydraulic properties are the common result of particle size distribution (texture) and aggregation (structure).
