Question

what do you mean by humus

Answer 1

humus : the organic component of soil, formed by the decomposition of leaves and other plant material by soil microorganisms

Answer 2

Humus is dark brown in colour and rich in minerals. It increases the soil fertility and the water retaining capacity of the soil. It is the top most layer of soil. Humus refers to organic matter that has reached a point of stability, where no further breakdown will take place and might, if conditions do not change, remain as it is for centuries.
