The remediation method of sandy land in the feldspathic ...

Therefore, the permeability of sand could be reduced by the addition of the feldspathic sandstone to better the water retention in remediated soil. When the ratio of feldspathic sandstone to sandy land soil was 1:2, the Ks value was 0.49 mm/min, which was 14.5 times less than the sandy land soil (Pei et al. 2013).
