Reclaim the salt affected soils using continuous and intermittent leaching methods

Abstract

A laboratory experiment was conducted to measure the saturated hydraulic conductivity (Ksat) of two surface soil samples, saline soil (S1) and saline soil (S2), collected from the Taworgha Agricultural Project, located about 300 km east of Tripoli, Libya, before and after leaching processes using the intermittent and continuous leaching techniques with the constant head method as described by Klute and Dirksen (1986). Hydraulic conductivity depends on the soil pore space, the proportion of air in the soil, and the soil salt content. The Ksat under intermittent pouring (M1) was lower than the continuous pouring (M2), and the opposite was true for soils with a 6 PV concentration (PV) and a 3 PV concentration (PV),
