Usually refers to the process in which aerobic microorganisms degrade and convert organic matter in organic manure waste into stable humus under good ventilation conditions and sufficient oxygen. This process ultimately forms stable, harmless, and beneficial fertilizers for plant growth, hence it is also known as aerobic composting.
This is an environmentally friendly and sustainable treatment method that converts organic waste into valuable fertilizers while reducing environmental pollution and resource waste.
Composting process: Aerobic composting is usually carried out by stacking organic waste (such as plant residues, food residues, livestock manure, municipal sludge, etc.) in a suitable compost pile, with the most common being the stack style. The size and structure of the stack are crucial for maintaining proper ventilation and humidity. Ventilation can be achieved by laying ventilation pipes at the bottom of the compost pile or flipping the pile.
Ideal conditions: Aerobic composting requires some ideal conditions, including appropriate temperature (usually between 50 ° C and 70 ° C), moderate humidity (kept moist but not too humid), appropriate C/N ratio, and an appropriate supply of oxygen. These conditions help promote microbial activity, thereby accelerating the decomposition process of organic matter.
Microbial action: Microorganisms play a crucial role in the aerobic composting process. These microorganisms include bacteria, fungi, and other microorganisms that decompose organic waste and convert it into stable organic fertilizers. The heat generated during this process also helps to kill some pathogens and weed seeds, making them safe and stable for use in crops.
Composting time: The time for aerobic composting depends on various factors, including the type of raw waste, the size and structure of the compost pile, temperature, etc. Normally, aerobic composting takes several months to ensure that organic waste is thoroughly decomposed and converted into fertilizer. The use of air flow film for film mulching composting fermentation can greatly accelerate this process, usually shortening it to 21-28 days.
Application and benefits: Aerobic composting technology can reduce the amount of organic waste and convert it into high-quality fertilizers for use in agriculture and horticulture. This helps reduce soil pollution, improve soil quality, and increase crop yields. In addition, aerobic composting can also help reduce greenhouse gas emissions, as the methane gas generated during the composting process can be effectively controlled and treated.
Aerobic composting is mainly divided into outdoor composting, film covered aerobic composting, and trough flipping.
