... predicting salts transport in fields in China The objective of this study was to examine the change in hydraulic conductivity that occurs as a result of adding the gypsum, and to examine the transport ... the beginning of leaching, decreased after a peak, and then increased and decreased again This behavior indicates that the initial leaching is like Na+ leaching, and the surplus Ca2+ is drained ... conductivity and salts transport were examined Expulsion of the salts after reclamation was confirmed by the soil column experiment The initial leaching of Na+ was faster than the leaching of any of the...
