The importance of agriculture in the Russian economy is relatively small, which is a characteristic feature of developed economies (about 4% of GDP). However, agriculture represents a significant share in the structure of the employed – 9.2%. The use of agriculture as self-sufficiency food has become essential after the embargo imposed on imported products. Russia as a country has a large area of land. The surface of used agricultural land after a fall in the nineties has stabilised at a level of 800 thous. km2. At the same time intensified agricultural production has resulted in increased performance and larger crops. Due to the progression of technology there is an opportunity for the development of agriculture in Russia.

The aim of this paper was to study comparatively the amount, chemical composition and energy content of litter from forest and grassland ecosystems along a transect in Central Siberia, running from the north (68°N, Forest tundra) to the south (50°N, Dry steppes); it is about 2 000 km. In the boreal forests litter standing crop ranges from 15 to 78 t·ha⁻¹ d.w., in subboreal birch stands – it is about 17 t·ha⁻¹ d.w. and in grasslands – the litter standing crop decreases southward along the transect from 6 to 1.5 t·ha⁻¹ d.w. All kinds of litter are rich in reduced compounds and have negative oxidation degree. Nevertheless oxidation degree increased from North to South in both ecosystem groups: from –0.6 to –0.3 in the boreal forests and from –0.5 to –0.2 in the subboreal ecosystems. The chemical composition of litter is specific and differs from both initial substrates, i.e. phytomass and products of humification. The litter contains as many carbon as fulvic acids, as many oxygen as humic acids and much more hydrogen than both acids together. Energy content values of litter were estimated to be lower than that of humic acids and higher than energy contents of fulvic acids. The transformation of litter organic substances seems to be shifted to the formation of fulvic acids. The content of minerals in litter changed in both series (forest and grassland) in the following order Si> Ca> F> Al> S> Mg> K> P> Na.
