WebbSoil under no-tillage had lower hydraulic conductivity (5.0 cm day-1) than under subsoil tillage (15.5 cm day-1) or minimum tillage (14.3 cm day-1) during 1 of 2 years in continuous crop due to a reduction of soil porosity. Residue cover at sowing was greater under no-tillage (60%) than under subsoil or minimum tillage (10%) in continuous crop. Webb2 sep. 2024 · Saturated hydraulic conductivity ( Ks) is a quantitative measure of saturated soil properties and it is essential for designing irrigation, drainage and waste water systems, modelling studies for understanding and prediting rates of infiltration, runoff, erosion, seepage, upflux, solute transport and migration of pollutant to groundwater.
