Characterization of soil low-molecular-weight organic acids in the Karst rocky desertification region

Xiaoliang LI, Xiaomin CHEN, Xia LIU, Lianchuan ZHOU, Xinqiang YANG

Frontiers of Environmental Science & Engineering 2012, Volume 6, Issue 2,   Pages 195-203 doi: 10.1007/s11783-012-0391-1

Abstract: LMW) organic acids play important roles in the soil-forming process and the cycling of nutrients in Karstorganic acids (including lactate, acetate, formate, malate, and oxalate) in soil solution over the KarstThere were also significant difference in the contents of these acids among four phases of rocky desertification, and their concentrations decreased with the aggravation of rocky desertification.desertification process in Guizhou Province.
