Modern Ecological Characteristics of Stepped Mountain-Forest Brown and Mountain-Gray-Brown Soils of the Shahdag National Park

Mountain forest brown steppe soils and mountain gray-brown soils are analyzed. Their productivity indices are considered, including humus level, total amount of nitrogen, phosphorus, sum of exchangeable bases and acidity. The study showed that mountain forest brown steppe soils demonstrate slightly more favorable fertility characteristics compared to mountain gray-brown soils, in particular, the humus content in them exceeds by 0.41% on average.
