| Abstract: | A total of 129 samples were collected and the environmental geochemical characteristics of 13 kinds oftrace elements and Fe in the yellow brown soil were studied, which has the largest distribution area in zonal soilsof middle and lower reaches of the Yangtze River. The main results are as follows: (1) Pb、Ni、Cr、Hg、Co、V、Mn、F and Fe are relatively high in total contents, As、Se、Cu、Zn and Cd are moderate or little lower. Theavailable B、Cu、Zn and Mo are all insufficient. (2) Most of trace elements have their highest total contents in thesubsoil and their highest available contents in the epipedon. (3) The sequences of total contents of trace elementsin the yellow brown soil are basalt soil＞limestone soil＞ granite soil. (4) The positive correlation between thecontents of total and available Zn & Mo arrives to significance or extreme significance level in the yellow brownsoil of Hubei province. The positive correlation between available contents of B & Mo and pH of the yellowbrown soil is proved to be extreme significance. But for Fe & Zn, the negative correlation is also the same level.The contents of available B、Mn、Cu、Zn and Mo have significant or extreme significant positive correlation withthe organic matter content in the soil. The authors think it necessary to plough deeply and apply organic fertiliz-er to improve the contents of available trace elements in the yellow brown soil. |
