Abstract:This paper studied the characteristics of aggregate composition, organic C content and phenanthrene distribution and leaching in ferric-accumulic stagnic anthrosol from the Tai Lake region under different long-term fertilizations. The results showed that 0.25 ~ 0.02 mm aggregate fraction was dominant, consitituted of 38.3% ~ 43.6% of total aggregates, while clay fraction only constituted of 7.9% ~ 11.7% of the total aggregates. Pig-manure and straw increased significantly the content of 2.00 ~ 0.25 mm aggregate fraction. Organic C content of 2.00 ~ 0.25mm aggregate fraction was highest, reached to 20.57 ~ 28.32 g/kg, pig-manure and straw could increase it too. Fertilization influenced phenanthrene content, chemical fertilizer (CF) increased it most, followed by non-fertilizer (NF), conventional fertilizers (CFM) and straw (CFS). Phenanthrene distributions in aggregate fractions under different fertilizations were similar, mainly contained in <0.002mm and 2.00 ~ 0.25 mm aggregate groups. And long-term fertilization didn't influence significantly phenanthrene leaching in original soil and aggregate fraction, no phenanthrene leaching occurred in electrolyte solution.
