GENERAL GEOLOGY

Detailed explanation-1: -Humus is dark, organic material that forms in soil when plant and animal matter decays. When plants drop leaves, twigs, and other material to the ground, it piles up. This material is called leaf litter. When animals die, their remains add to the litter.

Detailed explanation-2: -Organic material is anything that was alive and is now in or on the soil. For it to become organic matter, it must be decomposed into humus. Humus is organic material that has been converted by microorganisms to a resistant state of decomposition.

Detailed explanation-3: -In agricultural terms, humus can be described as well aged compost. Organic matter decomposes molecules into smaller molecules by microorganisms in the soil. Most of the chemicals in this organic matter can be extracted by microorganisms and can be shared with other beings within the soil.

Detailed explanation-4: -Organic matter is anything that contains carbon compounds that were formed by living organisms. It covers a wide range of things like lawn clippings, leaves, stems, branches, moss, algae, lichens any parts of animals, manure, droppings, sewage sludge, sawdust, insects, earthworms and microbes.

Detailed explanation-5: -Soil Organic Matter & Humus – What’s The Difference? SOM and humus are distinctly different. SOM includes all fractions of organic material in it’s multitude of stages of degradation, whereas humus is only the humic substances present at the end of the biological degradation of organic matter.
