The importance and place of the photosynthetic carbon sequestration in the organic branch of its global cycle

Results of comparative analysis of turnover times and the capacity of major global pools of organic carbon Ere presented; the place of photosynthetic carbon sequestration is defined; concept of its catalytic role in the regulation of the organic branch of the global carbon cycle is ground. Concept of reservoir-flux model of photosynthetic carbon sequestration and of the net photosynthetic production at the territory of Northern Eurasia is suggested.
