Humus content of the main soil units in Poland

Humus content of soil

Humus content in soils fluctuating in broad range.

On humus content have influence the following factors:

amount and quality of humus, which get at soil in given bioecological zone
tempo of humification process of organic matter
tempo of mineralization of humus, which is contain in soil
chemical, physico-chemical and physical soil properties
amount and quality of mineral compounds contained in soil
