What is humus soil Short answer?
Humus is the dark, organic material present on top of the soil. This organic matter mainly consists of dead and decaying animal substances, dried leaves, twigs, grasses, vegetables, microbes and other nutrients. Humus is naturally obtained soil, which can be easily produced through a process called composting.
What is soil humus content?
humus, nonliving, finely divided organic matter in soil, derived from microbial decomposition of plant and animal substances. Humus, which ranges in colour from brown to black, consists of about 60 percent carbon, 6 percent nitrogen, and smaller amounts of phosphorus and sulfur.
Where is humus found in the soil profile?
topsoil
Soil is usually layered. The uppermost layer is called topsoil and this layer contains humus, plant roots, and living creatures. The more humus found in topsoil, the more nutrient rich the topsoil and the better the conditions for growing plants. The middle layer is called subsoil.
What is the role of humus in soil?
Humus gives the soil the ability to absorb and retain moisture. Such soils do not dry out and require significantly less irrigation. Humus provides a reservoir for the plant nutrients available in the soil for balanced plant growth.
What is humus and what is its function?
Humus is the organic compound of soil which is formed by the decomposition of leaves , some organisms and other plant material by soil microorganisms . It provides nutrients to the soil. Helps in improving tilth, aeration and retention of moisture and increasing buffering and exchange capacity of soils .
What is humus what is its significance?
More precisely, humus is the dark organic matter that forms in soil when dead plant and animal matter (including aerobic compost) breaks down further, specifically through the action of anaerobic organisms. Humus has many nutrients that improve the health of soil, nitrogen being the most important.

Hummus/Place of origin
Why is humus important for?
Humus is a dark brown nutrient rich dead and decaying organic matter present in the soil. It increases the water holding capacity of the soil, provides nutrients and keeps the soil intact. It helps to increase the fertility of the soil and promotes better growth of plants.
What is a soil profile and why is it important?
The soil profile is an important tool in nutrient management. By examining a soil profile, we can gain valuable insight into soil fertility. As the soil weathers and/or organic matter decomposes, the profile of the soil changes.
What is humus in agriculture?
As decomposition of dead plant matter and animals occurs, nutrients held within the plant matter or animal is released to the soil. This end result of the decomposition is known as humus. This humus represents up to 1 to 5% of the dry weight of the soil.
