Organic Matter

Organic matter refers to the material that comes from living organisms, such as plants and animals. It is composed of complex organic compounds containing carbon, hydrogen, oxygen, nitrogen, and other elements. Organic matter is an essential component of soil, playing a crucial role in the fertility and overall health of the soil. It is also a key part of the carbon cycle, as it is involved in the cycling of carbon between the atmosphere, soil, and living organisms.

Importance of Organic Matter

Organic matter contributes to soil fertility by providing nutrients for plants, improving soil structure, and enhancing water retention. It also supports a diverse microbial community in the soil, which is essential for nutrient cycling and plant health. Additionally, organic matter helps to sequester carbon, playing a role in mitigating climate change.
