The total Zn contents in soils in the Hami Basin of Xinjiang range from 30.5～118ppm.The mean value of total Zn is 77.11ppm

and it is lower than thatof mean valus (100ppm) of the whole country.The effective Zn contents insoils are 0.1～1.14ppm

and the mean is 0.407ppm.If we take 0.5ppm as acritical value of lacking Zn in the soil

the sampling numbers of less than 0.5ppmaccounts for 73.5% of the total sampling number

The content of effect Zn bearpositive relationship with the content of organic matter and the soil texture.Thecontent of effect Zn in the soil profile are higher in the surface layer than in thelower layer.The yields of wheat and grape in Zn-lacking soils employed Zn-fertilizer can increase by 3.7～22.7% and 31.1%

respectively.
