Abstract
Results of the organic carbon stock assessment in pools of forest soils and forest litter on the forest monitoring plots in different natural zones of Ukraine are presented. Organic carbon in forest ecosystems is concentrated in phytomass, litter and deadwood, and in soil humus. During the study the amount of forest litter stock, soil density and carbon content in soils (in 30-sm depth) and in litter were determined. For plain forests the average carbon stock in litter is 8±1 tonnes of C/ha, this index for coniferous is 13,1±2 tonnes C/ha, and for deciduous – 4±0,4 tonnes C/ha. Average carbon content in forest litter under our research (38 %) is close to the coefficient, recommended by IPCC (37 %). Maximum carbon stock in soils of plain forests is observed in Forest-steppe zone (75 tonnes C/ha); in soils of Forest zone carbon stock is 49 tonnes С/ha and in Steppe zone – 43 tonnes C/ha. In Oak forests this index is 88 tonnes C/ha, and in pine forests– 41 tonnes C/ha. Average stock in forest soils pull in forests of the plain part of Ukraine is 67,3 tonnes C/ha, and in mountain forests – 96,6 tonnes C/ha. Obtained results are preliminary. It is necessary to continue the research for more detailed and precise assessment, with covering the variety of forest types and spatial and time dynamics of carbon stock in forest pools.
