چکیده

Understanding the relationship between root systems, soil macropore networks, and hydraulic properties is important to better assess ecosystem health. In this study, treatments were performed in forested wetland soils with different vegetation densities, i.e., large (LWa) small communities (LWb) of reed (Phragmites australis (Cav.) Trin. ex Steud.). At each plot, three undisturbed PVC cylinders (10 cm diameter 50 height) obtained, X-ray microtomography (μCT) scanning was used determine architectures. Results showed that values total length volume at LWa significantly larger than those LWb (p < 0.05). Imaged macroporosity, volume, density, node branch mean surface area, diameter, 0.05), whereas length, tortuosity LWa. Total positively correlated saturated conductivity. conductivity, negatively conclusion, systems networks constitute a complex synthesis inside environments, together affect hydrological responses.

Effect of pH on Saturated Hydraulic Conductivity and Soil Dispersion

The adverse effects of exchangeable sodium on soil hydraulic conductivity (K) are well known, but at present only sodicity and total electrolyte concentration are used in evaluating irrigation water suitability. In arid areas, high sodicity is often associated with high dissolved carbonate and thus high pH, but in humid areas high sodicity may be associated with low pH. To evaluate the effect o...

Study of Saturated Hydraulic Conductivity Variations in Different Aggregate Size Distributions in an Agricultural Soil

Saturated hydraulic conductivity (Ks) is one of the most important soil physical characteristics that plays a major role in the soil hydrological behaviour. It is mainly affected by the soil structure characteristics. Aggregate size distribution is a measure of soil structure formation that can affect Ks. In this study, variations of Ks were investigated in various aggregate size distributions ...
