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.

The formation of complex organic matter in soil is called Humus
Decaying organic matter in the soil is called humus. When it is added to the soil deliberately, it is called compost.
It increases the fertility of the soil.
Organic matter is matter that is from living sources, such as animal manure, leaves, grass clippings etc. As the organic matter breaks down, worms, grubs and microorganisms incorporate it into the soil.

Inaccuracy in the particle size and therefore in soil characterization, classification and texture is the reason for why organic matter has to be removed in soil hydrometer tests. Samples may contain carbonates, organic matter, oxides and soluble salts. All four of the above-mentioned soil constituents need to be removed since they bind soil particles into bigger sizes.
