Research results show that compost was created at the rate of C / N: 25/1 by mixing ingredients 2.5 grams of cow manure, 3g of organic waste, 0.01g of coir based on calculation of content. C and N in each material; With the humidity of 60% based on the calculation of the moisture content from the compost materials combined with the amount of water to add is 670ml, from which a Compost fertilizer has been produced. Determination of the optimal values for the mixratio and function has been verified on experimental crops. Research also shows that the use of probiotics in composting will shorten the compost time, limit the odor escaping from the compost.
