Humic acids are natural occurring macro-molecules that fulfill important functions in soil, as e.g. they store water and nutrients in a plant availably form and thus allow healthy plant growth. Therefore, they are particularly of interest for plant cultivation under extreme climatic and edaphic conditions, i.e. in the case of desert landscapes, extreme drought and nutrient deficiency. Humic acids can technically be extracted from fresh or carbonized organic material as e.g. lignites.
