Abstract: The average of soil total zinc of Hebei province is 73ppm, below the average of the counrty (l00ppm) , above that of the world (50ppm) . Soil zinc available averages 0.53ppm.The soil available zinc content of 78.8% cultivated land of this province is below the critical value (0.50ppm). Thus,microelement zinc has become a potential limiting factor to the farming and animal husbandry.The effects of soil parent material, texture, organic matter, CaCO3, available phosphorous and soil water and temperature on the growth and decline and the distribution of available zinc were discussed in this paper, and so statistical data of relationship between them were established and available zinc distribution map was made. According to the economic benefit of zinc-fertilizer, the utilization demarcations of soil available zinc were defined.

Key words: Soil zinc, Grows and decline, Hebei
