“…Moreover, part of soil organic matter may be very old (i.e. several millennia) and was consequently not produced by the current forest vegetation [see for instance Kulakova (2012)], making interpretation of differences among tree species tricky, particularly in studies without common-garden or paired-stand designs. Even if the influence of tree species on long-term accumulation of the stabilized C org pool in soils remains unclear, it appears that the turnover rate of the soil pool of recent C org (i.e.…”

Influences of evergreen gymnosperm and deciduous angiosperm tree species on the functioning of temperate and boreal forests

It has been recognized for a long time that the overstorey composition of a forest partly determines its biological and physical-chemical functioning. Here, we review evidence of the influence of evergreen gymnosperm (EG) tree species and deciduous angiosperm (DA) tree species on the water balance, physical-chemical soil properties and biogeochemical cycling of carbon and nutrients. We used scientific publications based on experimental designs where all species grew on the same parent material and initial soil, and were similar in stage of stand development, former land use and current management. We present the current state of the art, define knowledge gaps, and briefly discuss how selection of tree species can be used to mitigate pollution or enhance accumulation of stable organic carbon in the soil. The presence of EGs generally induces a lower rate of precipitation input into the soil than DAs, resulting in drier soil conditions and lower water discharge. Soil temperature is generally not different, or slightly lower, under an EG canopy compared to a DA canopy. Chemical properties, such as soil pH, can also be significantly modified by taxonomic groups of tree species. Biomass production is usually similar or lower in DA stands than in stands of EGs. Aboveground production of dead organic matter appears to be of the same order of magnitude between tree species groups growing on the same site. Some DAs induce more rapid decomposition of litter than EGs because of the chemical properties of their tissues, higher soil moisture and favourable conditions for earthworms. Forest floors consequently tend to be thicker in EG forests compared to DA forests. Many factors, such as litter lignin content, influence litter decomposition and it is difficult to identify specific litter-quality parameters that distinguish litter decomposition rates of EGs from DAs. Although it has been suggested that DAs can result in higher accumulation of soil carbon stocks, evidence from field studies does not show any obvious trend. Further research is required to clarify if accumulation of carbon in soils (i.e. forest floor + mineral soil) is different between the two types of trees. Production of belowground dead organic matter appears to be of similar magnitude in DA and EG forests, and root decomposition rate lower under EGs than DAs. However there are some discrepancies and still are insufficient data about belowground pools and processes that require further research. Relatively larger amounts of nutrients enter the soil-plant biogeochemical cycle under the influence of EGs than DAs, but recycling of nutrients appears to be slightly enhanced by DAs. Understanding the mechanisms underlying forest ecosystem functioning is essential to predicting the consequences of the expected tree species migration under global change. This knowledge can also be used as a mitigation tool regarding carbon sequestration or management of surface waters because the type of tree species affects forest growth, carbon, water and nutrient cycling.

Aim. Determination of phytocenosis productivity, nitrogen concentration and reserves in blocks of plant associations and by soil types in the North‐Western Precaspian region of Russia. Methods. Comprehensive research on the accumulation of organic matter and nitrogen in five blocks of plant matter, six plant associations and three types of soil by season using well‐known methods of accounting and analysis of soils and plants. Results. The regularities of phytomass formation, changes in nitrogen concentration and reserves in the main soil types and six plant associations for the 2011–2018 seasons were revealed. Conclusions. Ephemeroid‐wormwood‐cereal, ephemeroid‐wormwood, cereal‐wormwood, forb‐campfire and mixed‐grass‐campfire plant communities formed on light chestnut soil are the most productive, with a total productivity of 24.34 t/ha. The maximum nitrogen concentration was observed in the cereal‐wormwood, wormwood‐saltwort, forb‐saltwort and cereal‐saltwort associations – 1.9, 1.97, 2.2, and 2.57%, respectively, which is due to the predominance of Artemisia taurica Willd., Artemisia lercheana Web.ex Stechm. and Salsola iberica Sennen&Pau. In associations where there are representatives of the Poaceae, Brassicaceae and Caryophyllaceae, nitrogen decreases to 1.72–1.74%. Its value was higher on light‐chestnut soil, being 1.82% of absolutely dry mass, while on meadow‐chestnut soil it decreased to 1.75 and on saline soil is typically 1.38%. In the root mass of plant associations, its indicators were 3.2 times less than in the above ground mass. Nitrogen reserves by blocks of plant matter formed the following decreasing series: roots ≥ green mass ≥ rags ≥ felt. In the input part of the balance in plant associations, 171.6 nitrogen accumulates on light‐chestnut soil, 63.1 on meadow‐chestnut soil, 49.1 kg/ha on automorphic typical saline soil, and 171.9; 64.3 and 58.1 kg/ha in the expenditure part, respectively. the balance of nitrogen in the first type of soil is formed with a minimum deficit of 0.6 kg/ha, 1.2 and 9 kg/ha, respectively.

В полупустыне Северного Прикаспия солонцы составляют около 25 % территории. Главной задачей при хозяйственном освоении почв солонцового комплекса является рассоление и рассолонцевание солонцов. Альтернативой дорогому и часто экологически опасному орошению солонцовых почв являются разработанные на Джаныбекском стационаре ИЛАН РАН приемы агролесомелиорации. Они включают плантажную вспашку, разрушающую солонцовый горизонт и вовлекающую в пахотный слой гипс, залегающий под солонцовым горизонтом, для рассолонцевания солонцов, посадку лесных кулис, собирающих дополнительное количество снега для рассоления почв. В работе исследовались почвы лесомелиоративной системы с узкими 18-метровыми межкулисными пространствами и однорядными кулисами из вяза приземистого (ulmus pumila l.) (Государственная защитная лесная полоса Чапаевск-Владимировка 1951 г. посадки) и почвы под естественными растительными ассоциациями. Межкулисное пространство практически не использовалось под сельскохозяйственные культуры, но почву ежегодно вспахивали для сокращения потерь влаги и поддержания процессов рассолонцевания. Цель работы заключалась в оценке калийного состояния целинных и мелиорированных солонцов. Показано, что запасы необменного и легкообменного калия в солонцах, расположенных между лесными кулисами, не изменяются, обменного калия-снижаются, а в почве под кулисами запасы всех форм калия увеличиваются. Изученные солонцы характеризуются невысокими величинами ΔК L , AR otg и AR o по всему профилю. В солонцовых горизонтах значения фактора интенсивности (AR) минимальны по профилю, что связано с уменьшением активности ионов К +. В пахотных горизонтах относительно гумусовых горизонтов целинных почв происходит изменение термодинамических показателейувеличение значений калийного потенциала и буферности почв по отношению к калию, что свидетельствует об ухудшении обеспеченности растений калием.
