Effect of Soil and Water Conservation Measures on Soil Chemical Properties

Kang Ling

Abstract

By analyzing the changes of soil nutrients, pH and cation exchange capacity(CEC) on the loess plateau after implement of the World Bank's Loan Project on soil and water conservation, the effect of soil and water conservation measures on soil chemical properties is studied. The results show that soil nutrients didn't change with time on cultivated sloping lands and wild grass lands, but soil nutrients on lands with measures of soil and water conservation increased with time, the contents of soil nutrients are higher, pH changed to neutrality and CEC increased.
