Abstract：The investigation results of nutrient elements in surface soil of Yiyuan County showed that the available contents of N , P, K, Ca, Mg, S, Cu, Zn, Fe, Mn and Si were abundant , while those of B and Mo were lack .The statistical results indicated that significant or very significant positive correlations were found between pH value and the available contents of K , Ca, S, B, Mo and Si, and significant or very significant negative correlations were found between pH value and the available contents of N , P, Fe and Mn.This find-ing suggested that the available contents of elements should not be completely controlled by pH value .Signifi-cant positive correlations were found between organic matter and the available contents of N , P, K, Ca, Zn, B and Si, which suggested that organic matter should be the important control factor promoting element activation .
