This paper deals with the distribution and the total and available contents of Fe, Mn, Zn,and Cu in soils of Xinjiang.The content of the total iron in soils of Xinjiang is very high (0.3-5.1%), but with a greater fluctuation of available iron (0.16-504ppm).Some of the soils such as brown desert soil, gray desert soil, relic saline soil, saline soil and rakyric soil are deficient in iron.The content of the total manganese (59-1550 ppm) in soils is moderate,but the content of the available Mn (0.38-41.6ppm) is very low.It has been found that the brown desert soil, gray brown desert soil, gray desert soil,sterozem soil, saline soil and takyric soil in Xinjiang are severely deficient in manganese.The contents of the total Zn (9-216 ppm) and available Zn (0.08-11.84 ppm) in siols are lower.The brown desert soil, gray brown desert soil,sierozem soil, brown soil and saline siol in this region are severely deficient in zinc.The contents of the total Cu (5-145ppm) and available Cu (0.06-19.20 ppm) in soils are higher.Most of the soils in the region are adequate in Cu with the exception of brown desert soil and gray brown desert soil which are mainly distributed in the gravel gobi.
