The relationship between the five micronutrients(B,Zn,Mn,Cu,Fe) in soil of Linyi city and the other factors was discussed in this paper.Concentrations of the five microelements exist obviously differences among different soil group,and Zn deficient in Lime concretion black soil and Zn,Mn,Cu,Fe sufficient in Brown earth or paddy soil.Parent material was one of the key factors affecting the content of micronutrients in soils.Contents of the five micronutrients were high in soil developed from base rock,while the micronutrients contents in soil developed from red soil parent material were low.Soil organic matter content showed significant positive linear relation with the contents of micronutrients in soil,especially for the of available Zn,B and Cu.
