Abstrakt
The aim of the study was to define contents of carbon in soil of pine and spruce stands of different age in post-agricultural lands as well as on soil designed to afforestation. Two phases of carbon sequestration were found: (1) decrease of carbon contents after planting (emission) due to soil preparation, and (2) accumulation of carbon during subsequent growth period. Carbon contents in soil of spruce stands were larger than those of pine. A difference in contents of carbon inside of planting line and between them was found and they were decreasing in the age of stands. Generally, the highest carbon level was found in the north than in the south Poland. An attempt to determine the whole carbon contents in forest soil on post-agricultural lands was made.
