Abstract

The humus of Republic of Armenia forest brown soils has been studied. It turned out that these soils are characterized by high content of humus; up to 11,2%, which gradually decreases parallel with the soil profile depth. The humus content in plant litter reaches up to the 21,8%. One of the most important features in the forest brown soils is a high hydrolysis character of humus. The total balance of carbon of humus substances is 17.0-43.6%, which shows the weak linkage of humus with the mineral part of the soil. In general the presence of black HA in the content of humin acids is not typical for forest brown soils. It is well known that in forest grey soil prevail FA and grey FA and the absence of HA, which are combined with exchanging Ca, moving R₂O₃- as well as with the acid reaction of the soil, which consider being main connectors of humic substances.
