Chemical Reaction and Control of Soil Physical Propertiesing solution, tending to decrease with increasing ESP and decreasing salt concentration (Quirk and Schofield 1955, McNeal and Coleman 1966, NcNeal et al. 1968). Soil hydraulic conductivity (HC) can be maintained even at high ESP level provided that the electrical conductivity (EC) of the percolating

Diagnostic Criteria and Methodology or estimated from measurements made: (1) on aqueous extracts of soil samples; (2) on samples of soil water, per se, obtained from the soil; (3) in situ using either buried porous salinity sensors which imbibe and equilibrate with soil water or four-electrode probes or time domain reflectometric ele
