Humus is inactive organic material, usually decomposed plants. Most soil has humus in varying amounts, which gives it the distinctive dark brown color. Humus is complex and is made up of a variety of substances that have decomposed to the point of being impossible to identify.Humus makes garden soil rich and provides nutrients to growing plants.umus is complex and is made up of a variety of substances that have decomposed to the point of being impossible to identify. Humus makes garden soil rich and provides nutrients to growing plants.
Humus formation is a process dependent on the amount of plant material added each year and the type of base soil. Both are affected by climate and the type of organisms present. Soils with humus can vary in nitrogen content but typically have 3 to 6 percent nitrogen.oil bulk density is equal to the dry mass of the soil divided by the volume of the soil; i.e., it includes air space and organic materials of the soil volume. The soil bulk density of cultivated loam is about 1.1 to 1.4 g/cm 3 (for comparison water is 1.0 g/cm 3). Soil bulk density is highly variable for a given soil.
