The Zn content of 18 selected soils in Mangyong River area was partitioned into the five fractions. The average contents of each fraction were 0.05, 0.33, 1.87, 3.07 and 94.68 % of the total Zn in water-soluble, exchangeable, chelated, organic and residual mineral Zn fractions, respectively. The organic Zn was significantly related to chelated Zn, "available" Zn, residual mineral Zn, SiO2 and organic matter content of soils. "Available" Zn, was affected by total Zn content positively, and by Fe or Mn content negatively
