Abstract:
For the last 5 years, palm oil plantation in Pakning Asal village in Bengkalis were burned in different frequencies.There were unburned soil, once burned soil and burned soil in several times (2-3 times). The purpose of this study were to look the difference in the content of total N, P, K and C/N in the soil burnt with the different fire frequencies. Total nitrogen content was analyzed using Kjeldahl method, phosphor and carbon content was determined using UV-VIS spectrophotometer and pottasium content was determined by Flame Photometer. The study showed that the total N content decreased from 0,32% to 0,25%, total P content increased from 0,0069% to 0,0087%, total K content decreased from 0,047% to 0,038% and then increased become 0,055%, while the value of C/N decreased from 16,13 to 22,32 after burnt for several times.
