Effect of soft rock as soil amendment on soil cone penetration resistance and bulk density 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 decreased soil cone penetration resistance and bulk density.The treatment with rate of 1:1(soft rock to sandy soil in volume)had the greatest effect on soil cone penetration resistance and bulk density averaged over the three years.
