How to do aerobic composting?

The concept and principle of aerobic composting:

The principle of aerobic composting: under aerobic conditions, the organic solid waste (mainly human excrement and feces) is biodegraded and decomposed by using the life metabolism of aerobic microorganisms in the compost—oxidation, reduction, synthesis and other processes. Biosynthesis. The main process of the process can be divided into five steps: pre-treatment, main fermentation, post-fermentation, post-treatment and storage. Aerobic composting has the advantages of fast and thorough degradation of organic matter, short decomposing time, high degree of harmlessness, no intermediate products and odor, good environmental conditions and high fertilizer efficiency of composting products. Therefore, aerobic composting is preferred in the treatment of municipal solid waste. Composting.

How to do aerobic composting?

As the saying goes: composting is good for a while, and it is good to pile it all the time. The premise of planting good vegetables and flowers is good soil. If you have the conditions, you may wish to make safe and nutritious compost soil yourself!

Materials needed for home aerobic composting

①Green materials: There are many nitrogen-containing elements, including vegetable leaves, fruit peels, residual flowers, bean cakes, vegetable scraps, plant ash, tea leaves, coffee grounds, etc.
②Brown materials: There are many carbon elements, including fallen leaves, straws, broken wood chips, straw, Chinese medicine slag, nut shells, dry gardening garbage, brown cardboard boxes, etc.
The most suitable carbon-nitrogen ratio for microorganisms in the process of decomposing organic matter is 25-30:1. If the carbon-nitrogen ratio is too large, the decomposition of organic matter will be slow, and if the carbon-nitrogen ratio is too small, it is not conducive to the growth and reproduction of microorganisms.
③EM bacteria, containing more than 80 kinds of beneficial bacteria, can help compost to accelerate fermentation and improve soil disease resistance.

Start composting

Aerobic composting, as the name suggests, requires maintaining the breathability of the composting material. You can use wooden boxes or boxes with holes around them to allow air to enter freely.
Using the sandwich composting method, stack it according to the method of one layer of brown material, one layer of green material, one layer of EM bacteria, one layer of soil (old soil can be used), and finally covered with a thick layer of soil, which can effectively prevent smell and flying insects.
After completion, place the compost bin in a location without direct sunlight and rain, and keep it in a slightly moist state by watering, creating an environment conducive to microbial activity, and being too humid is not conducive to air entry.
The speed of composting is determined by the size of the material cut and the temperature. It may only take 1 month in summer and 3 months in winter. After the compost soil is completely decomposed, there is no odor, and it will have the fragrance of the soil, and the color is dark brown that looks fat and oily.
Aerobic composting is a good choice if the home has a ventilated patio, because it has obvious advantages, fast speed and little taste.
It should be noted that composting materials are not fixed. You can use whatever materials you have on hand. The more types of materials, the richer the nutrients. Make the best use of the household waste around you to make the best use of it, which can not only nourish crops, but also reduce environmental pressure. This is the fun of composting.
