GENERAL GEOLOGY

Detailed explanation-1: -The thick brown or black substance that remains after most of the organic litter has decomposed is called humus. Earthworms often help mix humus with minerals in the soil. Humus contains many useful nutrients for healthy soil. One of the most important is nitrogen.

Detailed explanation-2: -Humus allows soil organisms to feed and reproduce, and is often described as the “life-force” of the soil. The process that converts soil organic matter into humus feeds the population of microorganisms and other creatures in the soil, and thus maintains high and healthy levels of soil life.

Detailed explanation-3: -The Scientific Definition of Humus It’s created through natural decay processes that take decades to complete. Humus is what remains after decaying plants, animals and insects are broken down into the smallest possible molecules. It’s been forming on earth for millions of years.

Detailed explanation-4: -Humus is the substance that is left over after plants and animals have undergone a long process of thorough decomposition done by earthworms, bacteria, fungi, and other microorganisms. It is found in the top few inches of soil. The color of humus is brown or black, and it has a loose, crumbly, and spongy texture.

Detailed explanation-5: -Humus is the dead and decaying bits of animals and plants present in the topmost layer of soil.
