The Comprative Study on Chemical Composition and Characterization of Humic Acid from Soil and Coal

Wu Liping1,Zeng Xiancheng2(1 Institute of Coal Chemistry,Chinese Academy of Sciences,Taiyuan,030001 2 China Humic Acid Industry Association,Beiging,100120)  
The soil humic acid is an important component of soil organic matters,which is also a significant link among supplying plants nutrients,maintaining the carbon cycle and reducing the emissions of greenhouse gas.This paper below demonstrates the similarities and differences between coal humic acid and soil humic acid by shudying the formation,concept,struacture and chemical features of theirs.The result showes that the two kinds of humic acid mentioned before are greatly similar in terma of composition,structure and chemical features,etc.Furthermore,because of the structural stabilization of coal humic acid and its great similarties to soil humic acid,coal humic acid can be used as the most effective supplementary source for soil organic matters,which has tremendously positive effects on soil improvement,fertilizer synergia,environmental protection and emission reduction efficiency.
