This research has an objective to develop Biochar Kiln by using appropriate technology which farmer in rural area can be used to make biochar for soil amendment. The experiments were set at Padeng Biochar Research Center, Petchburi Province. Biochar kiln was developed according to the Slow Pyrolysis (SLW) process. Material used for kiln and retort were metal drums of 200, 100 and 50 liters which is double standing drum system. Retort is for biochar production and kiln is used for firewood or other waste material to combust the biochar. Retort which is slow pyrolysis system, control no oxygen inflow and the temperature has controlled of about 500-600℃ to get the best quality of biochar. The results show that 8 small holes about 1 centimeter in diameter at the lower level of the kiln and by using firewood about 60% of the material for biochar is the best Biochar kiln. Charcoal and biochar is used with organic fertilizer to improve soil quality and Increase production yield on sorghum (Sorghum bicolor L.) Moench, Sweet corn (Zea mays L. var. saccharate), Groundnut (Arachis hypogaea L.) and Phoenix Mushroom (Indian Oyster, Lung Oyster). The experiments were set at Hui Sai Development Study Genter, Chaum District, Petchburi Province. Mixing biochar with original soil and organic fertilizer is tested on the proportion of 10% 20% and 30%. The results show that soil moisture is higher than the original soil and give high production yield. In case of use too much fertilizer, the soil will have higher acidity which will reduce the production yield. For Phoenix Mushroom, biochar mix with Para rubber sawdust on the proportion of 1:9 will give the highest production yield. The conclusion is that the cost of Phoenix Mushroom Production by using Para rubber sawdust mix with biochar is less than the original method.
