ORGANIC CARBON STOCK IN PASTURE LANDSCAPES ON THE TERRITORY OF THE CENTRAL BALKAN NATIONAL PARK
Lyudmila Malinova, Diana Karatoteva
Abstract: Aim of study is to determine the org. C stock in georeferenced sample plots on the territory of the Central Balkan National Park for the purposes of long-term observations and assessment of its change under the infl uence of natural and/or anthropogenic factors. The org. C stock was determined in 17 sample plots, arranged in pastures from the low-mountain, mid-mountain and high-mountain landscapes. The impact of the altitude on the org. C stock, bulk density of fi ne earth, total nitrogen and the ratio org. C/N was assessed within the range from 535 m to 1878 m. A positive correlation was determined between the org. C
stock and the change in altitude, as well as a negative one between the bulk density of soils and the altitude. Signifi cant differences in the org. C stock were determined according to the soil units. The results of the org. C stock in soils from georeferenced locations from low, mid and high-mountain landscapes can be used to develop time data series for the purposes of long-term observations and assessments.
