| Abstract: | Available and total contents of microelements (including B,Mo,Cu,Zn,Fe and Mn) in forest soils of Nanjing Zhenjiang hilly regions were analyzed,and contents of total N,available P,K,organic matter,pH values and mechanical composition of soils were also studied.Results showed that total contents of B,Zn,Mn in this region were all lower than the average contents of the whole country,and those of Mo,Fe,and Cu were relatively high.The distribution regularity varied among the forests and was different among the elements.The contents of available B,Mo and Cu were very low,that of Zn was a little higher,and those of Fe,Mn were rich in the regions.Contents of available microelements were mainly affected by total contents of microelements,O.M.and available P contents.The variance on the availability of various microelements in soils of different forests was also studied in the paper. |
