I. V. Tokareva, S. G. Prokushkin, A. S. Prokushkin The Influence of Freezing on the Content of Water-Soluble Organic Carbon in Litters // Forest Science (Lesovedenie). 2012. No 4. С.39-46. The short-term and long-term effects of freezing on the content of water-soluble carbon in litters were studied. The short-term action of temperatures (in vitro) up to - 5°C did not affect the microbial activity and the consumption of soluble carbon by microorganisms resulted in the reduction of its amount in the litter. Under lower temperatures (-10 and -15°C), the content of water-soluble carbon increased. The longer the period of their effects, the higher the content of soluble carbon. In the autumn-winter-spring period, the soluble carbon pool consisted of carbon of soluble organic matter forming due to the permanent microbial activity at - 5°C and of carbon forming due to the death of microorganism cells and decomposition of plant material at -10 and -15°C. Water-soluble organic carbon, litter, larch forest, freezing.. |
