Fig. 2. Soil structure and saturated hydraulic conductivity.

Fig. 2

Conceptual representation of changes in saturated hydraulic conductivity induced by the presence of soil structural features (a). Saturated hydraulic conductivity has been shown to increase with macroporosity45 (b) and with content of soil organic carbon content62 (c). In this study, the ratio between structural and textural saturated conductivity Ks,str/Ks,tex has been parameterized as a function of Gross Primary Production (GPP), which is used as a proxy of the degree of bioturbation activity (d).
