Contents of the soil Available Trace Elements and Their Availability Evaluation in Huzhou City of Zhejiang Province

The available contents of Fe, Mn, Cu, Zn, B and Mo in paddy soil, red soil and fluvo-aquic soil, the three main soils in Huzhou City of Zhejiang province were studied, and the availability of the trace elements were evaluated in this paper. The results showed that Mo was deficient in large areas, While B and Mn were insufficient in some soils, however, the contents of available Cu and Zn were high, and the content of available Fe was also high. Meanwhile, the correlations among the available contents of the different trace elements and the soil parent materials, soil pH and soil organic matter in the three main soils were also discussed.
