Compost – Biochemistry of Mixing Materials

There’s ALOT to say about composting.

What a subject. Wow!

Composting is the process of breaking down organic matter, such as leaves, food waste, and yard clippings, into a nutrient-rich soil amendment known as compost. It is a simple and natural way to improve soil fertility and reduce waste, and it has numerous environmental benefits, such as reducing the amount of waste sent to landfills and reducing the need for synthetic fertilizers. In this article, we will introduce the science of composting and describe the differences between aerobic and anaerobic microbial digestion, the different styles of compost, and the benefits of soil amendments. We will also discuss Korean natural farming and how it differs from standard composting practices.
The Science of Aerobic and Anaerobic Microbial Digestion
Composting is a complex process that involves the interaction of microorganisms, such as bacteria, fungi, and protozoa, with organic matter. These microorganisms decompose the organic matter, converting it into a nutrient-rich soil amendment. The type of composting process that takes place depends on the availability of oxygen, with two main types of microbial digestion: aerobic and anaerobic.
Aerobic composting is a process that takes place in the presence of oxygen, with microorganisms breaking down the organic matter through oxidation. It is the most common form of composting and is characterized by a warm, moist, and well-aerated environment, which promotes the growth of aerobic microorganisms. The composting process is fast, producing compost in several weeks to several months, depending on the conditions.
Anaerobic composting is a process that takes place in the absence of oxygen, with microorganisms breaking down the organic matter through fermentation. It is a slower process and produces a different end product than aerobic composting, with a lower pH and a stronger odor. Anaerobic composting is typically used for large-scale commercial composting operations and is often performed in enclosed containers or lagoons.
Different Styles of Compost
There are several different styles of composting, including thermophilic piles that are turned, static piles that are arranged and then sit, and vermicomposting that employs worms.
Thermophilic composting is a type of composting that involves the use of heat-loving microorganisms, which break down the organic matter at high temperatures. This type of composting is performed by turning the pile regularly to ensure an adequate supply of oxygen and to maintain the temperature. The composting process is faster than other methods and produces a high-quality compost in several weeks.
Static composting is a type of composting that involves arranging the organic matter in a pile and then leaving it to sit. This method is simpler than other methods, as it does not require the regular turning of the pile, but it is also slower, with the composting process taking several months to several years to complete.
Vermicomposting is a type of composting that employs worms to break down the organic matter. The worms, typically red wigglers, consume the organic matter and produce a nutrient-rich compost in a matter of weeks. Vermicomposting is a simple and efficient method of composting, and it has the added benefit of producing a high-quality compost that is rich in microbial life.
Soil Amendments and Composted Soil Microbiology
Soil amendments are substances added to soil to improve its fertility and structure. Compost is a valuable soil amendment, as it provides a wide range of benefits, including improved soil structure, increased nutrient availability, and enhanced microbial activity.
Adding composted soil microbiology custom made out of local indigenous microorganisms is one of the best things to add to soil.

We could go on about this for a while.
