Land fire will be impact to the physical and chemical characteristics of soil that caused of decomposition proces. The differentland fire frequency will be affect to different in the soil composition. Toknow how far that the composition is different so it need to do research about the contains of micro element such as Fe, Mo, Al available and ratio C/N in area Pakning Asal, Bengkalis Regency. The contains of Fe and C-organic was determinedusing Spectrophotometer UV-VIS, the contains of Mo and Al was determined using Atomic Absorbtion Spectrophotometer and the contain of N was determined by Kjeldahl method. Analysis result showed that contains of Fe, Mo, Al and ratio C/N inunburnt soil, once burned soil and several times burned (2 – 3times in last 5 years) there were 14,1566 mg/Kg, 15,3151 mg/Kg dan 5,7677 for Fe, 0,0548 mg/Kg, 0,1345 mg/Kg and 0,0830 mg/Kg for Mo, 4,4008 mg/Kg, 4,0624 mg/Kg dn 0,8594 mg/Kg for Al and was increased 16,6855, 20,6787 dan 25,5206 for ratio C/N.
