Abstract: :The various form contents of the iron, manganese, copper and zinc and the relationship between the organic matter and the various forms in the lessive was studied in this paper with the long-term position test method in the Sanjiang plain. It shows that the full content of the iron, manganese in the test soil is slightly lower than the average level and the full content of the copper, zinc is slightly higher than the average level of the soil in Heilongjiang Province. It also shows that the effective forms of the iron, manganese, copper and zinc are on a high level. The forms content order of the iron, manganese, copper and zinc is RES-Fe>OX-Fe>OM-Fe>EX-Fe>CARB-Fe, OX-Mn>RES-Mn>OM-Mn>EX-Mn>CARB-Mn, RES-Cu>OM-Cu>CARB-Cu>OX-Cu>EX-Cu, RES-Zn>OX-Zn>OM-Zn>EX-Zn>CARB-Zn. It is the significant or highly significant positive correlation between the effective forms of the iron, manganese, copper and zinc and the readily oxidizable carbon, humic acid, fulvic acid, pine Junction organic matter in the lessive. In addition to the full form iron, it is the significant or highly significant positive correlation between the full forms of the manganese, copper, zinc, the organic forms of the iron, manganese, copper, zinc, the exchangeable forms of the iron, manganese, copper, zinc and the total organic matter, the readily oxidizable carbon, humic acid, fulvic acid and so on.

Key words: soil organic matter, different nutrients, mutual relationship
