    Over the last 5 years of oil palm plantations in Pakning Asal Bengkalis burned with different frequencies, there are land that are never burned and land burned once. This study is to determine differences among the availability of Cu, Zn, Mn and C/N in the soil burnt with different fire frequencies. Analysis of the availability of Cu and Zn was done with Atomic Absorption Spectrophotometer (AAS), analysis Mn and total carbon using UV-VIS spectrophotometer, while for total nitrogen analysis was performed by Kjehdahl method. The results showed that the content of Cu, Zn, Mn are higher on the ground once burned compared to unburned ground that is 29,333 mg/Kg; 5,812 mg/Kg; 183,867 mg/Kg while the C/N be increased from 17 to 25. The frequency of fires were different in the last 5 years affects the availability of Cu, Zn, Mn and ratio of C/N.
