Genesis and characteristics of the soil in A-R stage in forest ecosystems of NP [National Park] Tara [Serbia]

Different types of soil in A-R stage formed on limestone and serpentinite in forest ecosystems in the National Park Tara were researched. Based on the specific effect of limestone on the soil genesis and evolution, two types of calcareous limestone bedrocks were distinguished: dense limestones, and soft, marly limestones. Three subtypes of black earth were studied on dense limestones. They are: organogenic, organo-mineral, and brownised soils. One soil type was researched on soft, marly limestones: rendzina, the leached variety. One soil type was researched on serpentinites, within the A-R stage, humus-siliceous soil (ranker), subtype eutric ranker. This paper also presents the evolution of ecological and productive characteristics of the study soils.
