【 摘 要 】

Effect of soft rock as soil amendment on soil saturated hydraulic conductivity and water holding capacity was investigated in a field experiment in a sandy soil in Mu Us Sandy Land of China in 2012-2014. Treatments includes four rates of soft rock to sandy soil in volume (0:1, 1:1, 1:2 and 1:5) were applied only in the first year. Adding soft rock amendments increased water hold water holding capacity; decreased soil saturated hydraulic conductivity. The treatment with rate of 1:1 (soft rock to sandy soil in volume) had the greatest effect on soil saturated hydraulic conductivity and water holding capacity averaged over the three years. Soft rock amendments showed promise for improving soil hydraulic parameters in Mu Us Sandy Land.
