Feasibility of organic fertilizer for poultry manure compost biochar to control the releasing major nutrients

This batch experiment was conducted to evaluate a major nutrient releasing impacts for different biochar application using a modified Hyperbola model through precipitation water for feasibility of organic fertilizer. The feeding stock for biochar was poultry manure compost, and then produced poultry manure biochar through pyrolysis system about 500℃. Furthermore, the poultry manure biochar was treated with Plasma for increasing its adsorption capacity. The input amount of sesame dregs was based on 320 kg ha-1 of nitrogen application, and the application amount of poultry manure compost was based on 2500 kg ha-1 for cabbage cultivation. The input amount of biochar was 20% of poultry manure compost application. The treatments consisted of control, poultry manure biochar and biochar treated with Prisma. The precipitation period was 120 days. The results were indicated that the soluble amounts of NH4-N was highest at 3673.5 mg L-1 in the control. The reduction rate in the addition of poultry manure biochar with plasma treated was 35.5%. The highest soluble amount of PO4-P was 1015.8 mg L-1 in the control. The reduction rates of PO4-P were 46.8% in the addition of poultry manure biochar with plasma treated compared to the control. Overall, the nutrient precipitation order was Control> Poultry manure compost biochar> addition of poultry manure biochar treated with Plasma. Therefore, it could be concluded that addition of the poultry manure biochar treated with biochar can be useful with controling the major nutrients for making the organic fertilizer.
