Question

What is humus and explain how humus add fertility to the soil

Answer 1

The dark organic material in soils, produced by the decomposition of vegetable or animal matter and essential to the fertility of the earth.

Humus, which literally means “earth” and “ground” in Latin, is made from decomposed plants and other organic materials¹. Because of its high ratio in organic compounds, humus is also very rich in microorganisms which help plants to absorb nutrients or to combat diseases. This makes humus a great solution for soil fertility². In nature, humus is the top layer of dark organic matter that forms in the soil when plant and animal matter decays.
One of the most important functions of humus is that it makes the soil more porous, improving soil aeration, infiltration and drainage.
