Preparation of Effective Microorganisms Based Compost Using Some Selected Wastes for Improvement of Plants Growth

Abstract

Solid waste disposal is the most pressing problem facing mankind throughout the world. The solid waste management plays a significant role to create a sustainable environment. Some vegetable wastes such as rice husk, cotton husk, coconut husk, pigeon-pea husk and chicken manure were selected for chemical analysis. The effective microorganism (EM) solution was prepared from kitchen vegetable wastes except onion and garlic peels to ferment for two months. The microorganisms that contain in prepared EM solution were studied by using microscopic morphology. The pH of prepared EM solution was measured by using pH meter. The compost was prepared from the vegetable waste materials and prepared EM solution by using aerobic method. The yield percent of compost was determined by calculation method. The yield percent of prepare compost was found to 55%. The mineral contents of compost and soil sample were measured by using EDXRF spectroscopy. The physicochemical properties of vegetable wastes, prepare compost and soil sample were determined. Planting the seedlings of some selected useful vegetables in various ratios of the prepare compost and soil sample. The growth rates of plant rates were found to be effective by the planting experiment.
