Abstract
The land fires caused changes in the structure and composition of the soil is like nutrient that effected growth of the plant around it. To know how far the effect of land fire with different frequency need to do research about the content of micronutrients such as Zn, Cu, Mn and ratio C/N in area Pakning Asal, Bengkalis Regency. The total content of zinc and copper were determined by using Atomic Absorption Spectrophotometer, and the manganese and of organic carbon were determined by using UV-Vis Spectrophotometer and total of nitrogen was analyzed using Kjeldahl method. The result showed that the total of Zn, Cu and Mn on soil that were never burned and several times burned (at least 2-3 times) increased from 0.8864 mg/Kg to 5.7844 mg/Kg for Zn content, whereas the Cu content of 35.3338 mg/Kg to 71.5318 mg/Kg and Mn content from 408.9461 mg/Kg to 526.8814 mg/Kg and the C/N ratio increased from 16.6855 to 25.5206.
