Humus supplies plants with food and minerals such as nitrogen, calcium, magnesium and phosphorus
Humus is a source of food to the microorganisms in soil which influence the formation of high quality soils.
Decomposition of humus yields various acids which contribute to further weathering of rock materials.
Humus has a high water holding capacity. This helps soils to retain water while limiting leaching of dissolved minerals.
Humus is fertile and produces high agricultural yields.
