Аннотация: Four birch species are traditionally used for the sap harvesting in Russia. In the report, we discuss their spatial and ecophysiological features as well as the exudation, tapping periods and sap productivity. Biochemical constituents of the living tissues of the birches such as the wood, outer and inner bark, twigs, leaves, buds, roots, and exudated birch sap are also reviewed. We show numerous useful wooden, medicinal, tanning, coloring as well as feeding and decorative properties. Chaga - a fungi-parasite developed on the stems of the birch trees, is mentioned to be famous due to its antitumor and/or especially anti-cancer activity. It is reported that the former birch sap production closed completely at the transition to a market-economy has restarted in the Russian Far East.

Аннотация: This study aimed to better understand the stabilisation of rice rhizodeposition in paddy soil under the interactive effects of different N fertilisation and water regimes. We continuously labelled rice ('Zhongzao 39') with (CO2)-C-13 under a combination of different water regimes (alternating flooding-drying vs. continuous flooding) and N addition (250 mg N kg(-1) urea vs. no addition) and then followed C-13 incorporation into plant parts as well as soil fractions. N addition increased rice shoot biomass, rhizodeposition, and formation of C-13 (new plant-derived C) in the rhizosphere soils under both water regimes. By day 22, the interaction of alternating flooding-drying and N fertilisation significantly increased shoot and root C-13 allocations by 17 and 22%, respectively, over the continuous flooding condition. The interaction effect also led to a 46% higher C-13 allocation to the rhizosphere soil. Alone, alternating water management increased C-13 deposition by 43%. In contrast, N addition increased C-13 deposition in rhizosphere soil macroaggregates under both water regimes, but did not foster macroaggregation itself. N treatment also increased C-13 deposition and percentage in microaggregates and in the silt and clay-size fractions of the rhizosphere soil, a pattern that was higher under the alternating condition. Overall, our data indicated that combined N application and a flooding-drying treatment stabilised rhizodeposited C in soil more effectively than other tested conditions. Thus, they are desirable practices for improving rice cropping, capable of reducing cost, increasing water use efficiency, and raising C sequestration.
