WebMar 24, 2016 · Along the vertical soil profile, soil saturated hydraulic conductivity under different treatments decreased from top to bottom. Within different treatments, the saturated hydraulic conductivity of BS treatment in the 0–20-cm layer was higher than that of CK and CK + C treatments by 24.68 and 21.58 %, respectively. WebJun 21, 2024 · The highest θ fc (0.087 cm −3 cm −3) and θ awc (0.064 cm −3 cm −3) were observed for soils amended with >2 mm biochar. The soil hydraulic conductivity increased with decreasing biochar particle sizes, with the exception of <0.063 mm biochar, which showed a significant (p ≤ 0.05) decrease in soil hydraulic conductivity compared … WebThe hydraulic conductivity proportionality constant, K, can be conceptualized as the relative ease of fluid passage through a porous material. It has direction and magnitude and is represented as a vector; however, the first part of this discussion presents it as a scalar value.
