Compost is a decomposed organic material that can be used to help grow plants and keep soil healthy. The main objectives of this research are to prepare compost from agricultural wastes and study the physical and chemical properties of agricultural wastes and prepared compost. These agricultural wastes are cow dung, rice husk, saw dust, sesame husk and chaff. The physical and chemical properties of agricultural wastes and compost were characterized by pH, moisture, organic matter, calcium, magnesium, sulphur, nitrogen, phosphorus, and potassium. The EM (effective microorganism) solution was prepared by using organic kitchen wastes except onion and garlic peels for mixing in prepared compost. The microscopic morphology of microorganism was also studies for EM solution. The results showed that the prepared compost has pH value 7.29, moisture (20.39%), organic matter (22.89%), calcium (1.96%), magnesium (0.61%), sulphur (0.07%), nitrogen (1.25%), phosphorus (1.62%), potassium (1.56%), iron (1.30%), manganese (0.02%), copper (0.03%), zinc (0.01%) and chloride (1.07%). The yield percent of prepared compost was found to (58.45%) based upon the amount of agricultural wastes. The physical and chemical properties of agricultural wastes and prepared compost were used in soil management in a good way to improve and maintain soil quality, soil fertility, and conserve the environment.
