Abstract
Based on survey result, oil palm plantations in the area Pakning Asal Bengkalis regency
in the last 5 years (2010 - 2015) were burned by different frequency. There were soil
that were never burned and once burned. The purpose of this research were to
determined the effect of fire with different frequency at the total content of Fe, Al, Mo
and C/N. The total content of aluminium and molybdenum were determined by using
Atomic Absorption Spectrophotometer. Iron and carbon total were determined using
UV-Vis Spectrophotometer. Total of nitrogen was analyzed using Kjeldahl method. The
result showed that the total of Fe, Al, Mo increased at the once burned soil and C/N
ratio increased at once burned soil . The total content of Fe, Al, Mo at the once burned
soil were 69.20 mg/Kg; 33.83 mg/Kg; 2.16 mg/Kg and the value of C/N ratio increased
from 16.51 to 20.59.
