Characteristics of dissolved organic matter fractions in black soil by long-term fertilization
The objective of this study was to investigate dissolved organic matter(DOM) of soil by long-term application located in Heihe, Harbin, Gongzhuling. The results showed that the concentrations of MW<1 ku in DOM fractions followed by OM, MNPK, CK, NPK; while in MW>1 ku, the concentrations of DOM fractions revealed opposite tendency. In addition, OM application could lead to less the degree of aromatization, while NPK application made a higher degree of humification in soil DOM.
