摘 要：
This paper deals with the effect of improving soil fertility by organic materials on the optical properties and the activation degree of humic acids from brown earth in field and incubation experiments. The results are summarized as follows; the logK and activation degree increased, whereas RF value decreased under treatment, which suggested that humic acids molecule became less complex and more aliphatic. The humic acids of 50- 250 um particle fraction were more sensitive to treatment. The concept and the method for evaluating the activation degree of humic acids was also provided first in this paper.
