Organic Matter Supply in Reclaimed Technosols of Bulgaria | Organic Matter Supply in Reclaimed Technosols of Bulgaria

إنجليزي. The present paper aims to count the organic matter supply in technogenic soils built in the main mining areas of the country. The studied soils differ in the method of reclamation and landuse. Organic matter in Technogenic soils reclaimed without humus layer is a dynamically changing, multicomponent system with different origin - naturally formed humus, coal admixtures and accidentally introduced carbon from spills of coal dust and ash. These components determine the unrealistically high content (average 3.59%) and mosaic distribution of organic matter, both in vertical and horizontal direction. Organic carbon supply for Не layer 0-6 сm in these soils amounted to 25.7 tha. The supply in the humus layer 0-30 сm of humus reclaimed technogenic soils is estimated to average 49.7 t/ha and саn be compared to that found for Leached smolnitsa (Vertisols) of Bulgaria. As а result of the single modal distribution of organic carbon in these soils the supply does not exceed 145 t/ha in 1 meter layer.
