Physical properties of saline soil.

Plastic limit (%)	Liquid limit (%)	Plasticity index (%)	Optimum water content (%)	pH value of soil solution	Cl^− concentration of soil solution (mg/L)^b	SO4^2− concentration of soil solution (mg/L)^b	Soluble salt content (%)
16.56	20.98	4.42	15.5	9.48	886.50	3326.20	4.0

^aThe solution was prepared at a mass rate of soil to deionized water ratio of 1 : 2.5. ^bThe solution was prepared at a mass rate of soil to deionized water ratio of 1 : 10.
