Cultivated layer soil samples were collected in 21 plots from main soil types in 4 cotton production areas in Xinjiang province and the soil analysis,soil adsorbing trials and pot experiments were conducted in 1996~2002 to study soil nutrient element status,the adsorbing ability of soil to nutrient elements and the bio-availability of nutrient elements by systematic approach systematically in main cotton soil types,the main results are as follows:the order of nutrient elements deficiency was N>P>Zn>K>Cu>S in Irrigated soil in Hetian area,N>P>Zn>K>Mn>Fe>Cu in Damp soil and Irrigated soil in Akesu area,N>P>Zn>Cu>Fe in Damp soil in Kashi area and N>P>Zn>S>Fe>Cu>Mn in irrigated gray desert soil in Shihezi area.
