Organic Matter

Organic matter is the material that makes up the living organisms, or comes from living organisms. It is made up of carbon-based compounds and is essential for life on Earth.

Composition of Organic Matter

Organic matter is composed of carbon, hydrogen, oxygen, nitrogen, and other elements. These elements combine to form a wide variety of organic compounds, such as carbohydrates, proteins, lipids, and nucleic acids.

Sources of Organic Matter

Organic matter comes from a variety of sources, including plants, animals, and microorganisms. When these organisms die, their remains decompose and contribute to the organic matter in the soil. Additionally, organic matter can also be found in decaying plant and animal materials, as well as in organic-rich sediments.

Importance of Organic Matter

Organic matter plays a crucial role in soil health and fertility. It helps improve soil structure, water retention, and nutrient availability. Additionally, organic matter serves as a source of energy and nutrients for soil organisms, which in turn contribute to the overall health of ecosystems.
