What is humus ? What are its functions - BYJU'S
Humus:- Humus is a substance made from dead leaves and plants, that put into the ground to help plants grow. Humus is partially decayed organic matter. Function of humus: It makes soil porous, thereby increasing its air and water holding capacity. It is rich in nutrients (e.g., minerals) that promote plant growth.
Humus is present in the topmost layer of soil. - BYJU'S
Q. Humus is found in all layers of the soil. True or False? True or False? Q. Arrange the following layers of soil in the correct order of their occurrence from topmost layer to the bottom most one.
Carbon Cycle - Definition, Process, Diagram Of Carbon Cycle
Carbon cycle is a process where carbon compounds are interchanged among the biosphere, geosphere, pedosphere, hydrosphere, and atmosphere of the earth.
Types Of Soil - Sandy Soil, Clay Soil, Silt Soil, And Loamy Soil
From a general perspective, “soil” is a very broad term and refers to the loose layer of earth that covers the surface of the planet. The soil is the part of the earth’s surface, which includes disintegrated rock, humus, inorganic and organic materials. For soil to form from rocks, it takes an average of 500 years or more.
(a) We must use cotton clothes in summer. - BYJU'S
d. Man made materials have more demand because of their characteristics like easy to use, low cost of production, cheaper products and variety of things which can be made from them. e. Humus is a natural material because its formation is a natural process. It is the dark-coloured layer of top soil that is rich in nutrients.

These kankar layers restrict the penetration of water and as such when water is made available through irrigation, the soil moisture is readily available for sustainable plant growth. Desert soils are profoundly found in western Rajasthan and contain little humus and organic matter. Types of Soil in India – Laterite Soil
Soil Profile - An Overview Of Layers and Content Of Soil - BYJU'S
This layer is rich in organic material and is known as the humus layer. This layer consists of both organic matter and other decomposed materials. The topsoil is soft and porous to hold enough air and water. In this layer, the seed germination takes place and new roots are produced which grows into a new plant. This layer consists of ...
Fertilizers provide humus to the soil. - BYJU'S
Manures provide a lot of humus to the soil. They are decomposed organic materials added to the soil to increase the fertility of soil and productivity of crops. Final answer: The given statement is false.
Soil Formation - BYJU'S
It is made up of four basic constituents; minerals, organic materials, air, and water. The three main components responsible for its texture are; sand, silt, and clay. Depending upon these three constituents the mineral texture of the soil varies. Leaves and organic constituents decompose to form the upper organic layer, known as humus.
What is Humification? - BYJU'S
Humification means the formation of humus. Humus is a black amorphous substance produced by the decomposition of dead and decaying organic matter by microorganisms. Humification differs from mineralisation. In mineralisation, as the name implies, inorganic nutrients are recycled. Organic matter is further decomposed to form inorganic compounds.
