Similar searches There are many factors that can affect the acceleration of the composting process. Those include the following: The concentration of carbon and nitrogen in the organic material. Microorganisms used in the composting process need carbon to give them fuel and nitrogen to make protein. 1. COMPOSTING PROCESS AND TECHNIQUES Types of composting The aerobic composting process Factors affecting aerobic composting Aeration Moisture Nutrients Temperature Lignin content Polyphenols pH value Techniques for effective aerobic composting Improved aeration The composting process slows if there is not enough nitrogen, and too much nitrogen may cause the generation of ammonia gas which can create unpleasant It is not necessary to increase the surface area when composting, but doing so speeds up the process. Insects and earthworms also break 14.4.1 Organisms Aerobic composting is a dynamic system wherein bacteria, actinomycetes, fungi and other biological forms are actively involved. Facultative and obligate forms of bacteria, actinomycetes and fungi are most active in this process. In the initial stages mesophilic forms predominate and Factors affecting composting process Composting is mainly microbial driven process. The activity of microorganisms depend on various environmental process continues the carbon content goes on reducing, due to the fact that, microorganisms when decompose organic matter 2/3rd of carbon is 4.3. Factors affecting composting There are some factors affecting composting, such as moisture content, C/N ratio, temperature and air flow etc. 4.3.2. Aeration Aeration is one of key factors affecting composting process. To maintain aerobic conditions in a composting mass, aeration Environmental Factors Affecting Composting A. Sludge Characteristics 1. Volatility of Sludge (VSS) 2: Moisture.Content - percent moisture 3. Ratio The process of adding compost to soil will improve the physical properties of the soil, inCreasing water retention, permeability, and aeration while reducing. Factors Affect Composting Process. Four main factors control the composting process: moisture content, nutrition (carbon:nitrogen ratio of the material), temperature and oxygen (aeration). • The composting process results in the generation of heat, carbon dioxide and water. It results in the production of a stable compost that contains no Mechanical Biological Treatment Process • Mechanical Biological Treatment (MBT) is a generic term for a range of processes that may be used • The composting process results in the generation of heat, carbon dioxide and water. It results in the production of a stable compost that contains no Mechanical Biological Treatment Process • Mechanical Biological Treatment (MBT) is a generic term for a range of processes that may be used Compost is a very varied material depending on feedstock and composting process. Though single key factors which cause this effect systematically could not be identified. Anyhow the presence of specific antiphytopathogenic micro organisms or consortia is a pre-condition.
