Description
Summary:The process of composting sugarcane residue by new bio-decomposer consortium formula contain specific microbes with different functions such as ligninolytic and cellulolytic microbes can improve the quality of agricultural waste. These bacteria have the potential to enhance sugarcane litter and other sugarcane residues. The fermentation process led to the C/N ratio of compost serves as a reference for the effectiveness of the decomposition process by bacteria. The research was designed as an alternative to producing organic fertilizers by using four bio-decomposer consortium formulas as ISAFCRI collection and EM4 as commercial bio-decomposer. The physicochemical characterization of 5 composts, including the C/N ratio of compost, is below 12-17, macroelements N, P, K available in compost are relatively high compared to the minimum requirement of SNI. The compost 5 with EM4 bio-decomposer appeared to have lower nutrient yields than compost using other decomposers. Compost 1 with formula one, which contains a consortium of lignocellulolytic bacteria, has excellent potential to be developed as a new bio-decomposer formula for processing sugarcane waste. The pilot test has shown that varieties of composts and organic fertilizers can be made from a mixture of sugarcane residue.
