Study on the effect of bio-charcoal from the palm oil production and the growth of palm oil. The trial operation of academic services, Kasetsart University, Krabi. 3-year-old oil palm conversion, planning a series of experiments, there are 4 4 trials RCBD repeatedly since 3 years total 2558 (2015)-2556 (2013) year using bio-charcoal powder quantity is not equal. 0, 5, 10 and 15 kg of fertilizer is used, and the Bills 15-15-15 number of 4.5 kg/ton/year. Experimental results showed that the year of the 2557 (2014) property does not vary significantly by statistics. But the trend of soil properties, set the trials entering 4 bio-charcoal from the palm oil 15 kg. There is a growing trend at most equal to 440.85 cm secondary is a series of experiments that provide bio-charcoal 3 from the oil palm 10 kg. The productivity and growth equal to the trials and 435.72 cm 1 don't put charcoal on Palm oil from biological volume and productivity growth are likely to equal the smallest 418.11 cm.
