New Valuable Tools for Assessing Some Environmental Impacts

By El-Shazly Hegazy

Estimating the root water uptake when using the stress form of modified Richard's equation, SSI*Β, involves the term soil hydraulic capacitance. SHC represents the response of the soil moisture reservoir toward a certain plant water demand under a certain atmospheric condition. Soil profile consists of layered capacitors. Each of which is recharged during the infiltration by precipitation, irrigation or both forming the constant shaped soil moisture profile. The easy available water is being stressed by discharging the soil capacitors during the root water uptake creating the variably saturated zone. In between the sink: source terms of Richard's equation, the discharge: recharge terms of soil capacitors or the root uptake: hydrological release terms, root navigates soil capacitors categorizing their energy states to select what has the easiest available water and bath to pass in order to water by exerting a minimum consumed energy. SHC depends on soil genesis, plant species, varieties, ages and adaptability, atmospheric conditions and the high tensile strength of liquid phase.
