Aeration, moisture infiltration and percolation, and nutrient availability and retention are reasons why soils need organic matter. Dark-colored, fresh-smelling, nutrient-rich organic matter comes from the natural breakdown of carbon- and nitrogen-rich dead, decomposing, dying animal and plant matter in soils. Organic matter facilitates the formation of air and water pore spaces, the defenses against over-draining and water-logging, and the dispersion of macro- and micro-nutrients for soil food web members such as plant roots.

organic matter important to plant growth is humus.
Another term for decayed organic matter is "humus".
Soil is primarily a mixture of weathered rock and organic matter. Weathered rock particles provide minerals and nutrients, while organic matter, such as decomposed plants and animals, adds fertility to the soil. Together, they support plant growth and ecosystem health.

Decaying organic matter in the soil is called humus. When it is added to the soil deliberately, it is called compost.
Soil fertility is closely linked to soil organic matter content. Organic matter contributes nutrients to the soil, improves soil structure, and enhances microbial activity, all of which are important for plant growth. Higher levels of soil organic matter generally lead to increased soil fertility and better overall soil health.
Organic matter in soil comes from decomposed plant and animal material. It enriches the soil by improving its structure, moisture retention, and nutrient content. Organic matter also supports beneficial microbial activity, which enhances soil fertility and overall plant health.
It increases the fertility of the soil.
The formation of complex organic matter in soil is called Humus
Loam soil typically contains around 2-3% organic matter. This percentage can vary depending on the location and management practices. Organic matter in soil is important for fertility, nutrient retention, and soil structure.
Soil that contains a large amount of organic matter is known as humus-rich soil. This type of soil is very fertile and ideal for plant growth, as organic matter helps improve soil structure, water retention, and nutrient availability.

Plants are the main source of organic matter in soil. When plants die or shed leaves, roots, and other parts, they contribute organic material to the soil, which decomposes and becomes part of the soil organic matter.
Organic matter in soil plays a crucial role in supporting plant growth and increasing soil fertility.
