Humus soil is soil made up of decayed organic material. Popularly, it refers to soil that is light in texture, dark brown or black in color, and sweet-smelling. It is considered the richest soil and is usually described as the ideal soil type.
The layer of soil that has little or no humus in it is the subsoil.  The top layer of the soil has the most humus in it because the dead  leaves fall from the plant and go bâ¦ack into the soil. Water and sun  also help give the plant humus.
