Abstract: In this study, the geostatistics method was used to analyze the content level of the essential micronutrient elements in farmland soil in Minfeng County, Xinjiang based on the test data of six micronutrients (Fe, B, Mn, Cu, Zn and Mo) in 85 farmland topsoil samples in the study area. The results showed that the nugget coefficients of Cu, Fe and Mn ranged from 25% to 75% with a spatial autocorrelation at moderate level, and the spatial variation was affected by both natural and artificial factors. The nugget coefficients of B, Zn and Mo in soil were lower than 25% with a high spatial autocorrelation, and the spatial variation was mainly affected by the natural conditions, such as the parent material and climate. The average contents of Fe, B and Zn were low, those of Mn and Cu were moderate, and the average content of Mo was high. There was a certain correlation among the six micronutrients in soil in the study area. The contents of soil micronutrients were affected by soil organic matter content and pH value to varying degrees.
