Currently, there is no consensus on how growing conditions affect the heartwood formation in Scots pine. Comparing results obtained by different authors difficult due to methodology differences and poor descriptions of objects used. We selected two sample plots (1) a blueberry pine forest nutrient-rich moist soil (2) lichen nutrient-poor dry performed their detailed characterization. The were located 22 km apart middle taiga subzone (Karelia Republic, northwest Russia). In each plot, we five...
Abstract The azonal organo-accumulative soils (Umbrisols) on shungite rocks and the effect of land use their properties ecosystem carbon stock have been studied. changes in soil profile morphology, main agrochemical microbiological characteristics upper horizons, C org mic stocks 100-cm layer, structure pools are analyzed. Pine forest (control), arable land, hayfield, young alder stand, middle-aged mixed examined. In contrast to zonal soils, a change does not considerably transform soils....
На примере южного агроклиматического района среднетаежной подзоны Карелии показан хронологический сукцессионный ряд восстановления лесных сообществ. Изучен период в 110 лет после забрасывания сенокосов и пашен, представленный 20- 65- 110-летними реперными древостоями. Процесс постагрогенной трансформации нарушенных участков идет направлении формирования зональных типов экосистем. Для изучаемых условий характерно восстановление хвойных древостоев с постепенным снижением доли лиственных по...
The influence of major nutrients’ reserves (available to plants) – nitrogen (N), phosphorus (P), potassium (K) in the top 25-cm layer soil on Karelian birch (Betula pendula Roth var. carelica (Mercl.) Hämet-Ahti) with non-figured and figured wood via antioxidant enzymes’ activity was investigated. analysis sites area where trees varying degree intensity were growing carried out. cambial zone sample during active growth period studied for AOS enzyme complex (superoxide dismutase (SOD);...
The article studies the mass of fine (up to 2 mm in diameter) roots woody species and patterns their distribution across soil profile post-agricultural forest communities middle taiga Karelia, Russia. Forest site characteristics were determined sampling plots established following conventional procedures. root was by monolith method. Analysis showed that young developed a greater compared older stands. total occupation top mineral layer higher than floor. In most cases, both coniferous...

The study was carried out in the Kivach Strict Nature Reserve situated middle taiga of Karelia. Albic Podzols formed over fluvioglacial sandy deposits different vegetation microgroups (lichen-, cowberry-, bilberry-, true moss-dominated) within a cowberry-type pine stand were surveyed. organic and mineral horizons these soils examined for structural functional setup microbial community. key groups microorganisms effecting nitrogen carbon cycling fluctuations bacterial numbers determined under...
В работе приводятся обобщенные данные комплексных исследований биотической компоненты почв, сформировавшихся в среднетаежной подзоне Карелии. Показано, что различных растительных микрогруппировках происходит изменение массы корней, численности микроорганизмов важнейших экологотрофических групп, а также экофизиологических показателей микробиоты. Изменение соотношения между исследуемыми микробиологическими показателями процессов трансформации органического вещества может отличаться результате...
