Because Humus decays rocks to make soil and soil is a food for plants, which are a food to animals, which are a food to us. So soil is a source if food directly to plants and indirectly to animals and humans (which are mammals)
in GENERAL a humus rich soil is better for plant growth, but it is dependant on the type of plant - e.g. plants that grow at the coast are at home in very sandy soils.
organic matter important to plant growth is humus.
Soil humus and sunlight
Humuscomes from dead organic material so it is rich in nutrients and carbon,necessitiesfor healthy plant growth. Also itimprovessoils water holding capacity.
Humus
Both humus and minerals contain nitrogen for growth of plants. Alluvial soils are rich in humus and minerals making them good for growth of plants.
Decomposition of dead organisms adds organic matter, or humus, to the soil; humus is necessary to support plant growth.

No, Humus is made from dead organic plants and animals.
the importance of mineral balance ensures that the plant is healthy and not lacking the mineral portion. pH is important to plants if the pH of the soil is high the plant will not survive and there will be poor growth of bacteria and a reduce in Mg K P and Ca. the humus holds the necessary nutrient that the plants needs to grow.
plants and humus
organic matter important to plant growth is humus.
Humus
yes
It is very good for the growth of plants because it contains humus and lome .Humans indirectly depend on soil for the growth of plants which provide food to humans. Humans use soil for farming, building houses, office buildings etc .
The Fertile soil contains lots of microorganisms which decompose the complex dead bodies of animals and plants into simpler substance called Humus.
