Based on long-term soil studies in Karelia the average carbon storages in soils of pine and spruce forests were estimated: 122.3 t ha-1 and 117.9 t ha-1, respectively. Higher values of the average storages in soils of pine forests are due to a high share of water-logged forest types. We found that average carbon storages in forest litter grows with soil moisture content from 7.6 to 24.3 t ha-1 in pine forests and from 11.1 to 61.3 t ha-1 in spruce forests. The storages in the layers 0-25 cm (9.1-170.4 t ha-1 in pine forests, and 31.2-228.6 t ha-1 in spruce forests), 0-50 cm (18.8-329.9 t ha-1 in pine forests, and 36.4-345.1 t ha-1 in spruce forests) and 0-100 cm (23.9-434.3 t ha-1 in pine forests, and 38.9-402.4 t ha-1 in spruce forests) were estimated. Total carbon storages in soils of Karelia were estimated: 614.6 Mt in pine forests and 276.2 Mt in spruce forests. Such a difference was due to the area of the forests: pine forests grow at more than 5 Mha, and spruce forests at 2.3 Mha. Our estimates differ from the total carbon storages estimate in soils of Russia.
