Abstract：In order to study the geochemical characteristics of nutrient elements in black soil region of central Jilin,the systematic field investigation was conducted,and the soil and corn seeds samples were col-lected.On the basis of statistical comparison of data,the spatial distribution characteristics of total contents and available contents of nine kinds of nutrient elements in soil in research areas and their contents in corn seeds were analyzed.The nutrient status in research areas was also evaluated.The results showed that the a-vailable contents of K,Ca,Mg,Fe,Mn,Cu,Zn and B were sufficient;the available content of Mo was ab-sent;the spatial distribution characteristics of nutrient elements in different research areas were different.The total contents of Ca,Mg,Mn and Mo were positively significantly correlated with their available contents;the available contents of K,Ca and B increased,while those of Fe,Mn and Mo decreased with the increase of pH.To solve the problem of lack of available Mo in research areas,using Mo fertilizer and bringing down the soil pH were the effective methods to increase the available Mo content.
