Progressive Growth

A progressive growth of anthropogenic soils and non-soil formations in the soil cover of the taiga forest zone and a general decrease in the ecological potential of soils necessitate the development of policies for the rational use of soil resources. The analysis of approaches to forest vegetation assessment of soils is carried out. The concepts of specific and resource potentials are introduced, and our own methodology for their assessment is developed. The methodology for calculating potentials was tested on the example of the Leningrad region, typical of the North-West of the European part of Russia and the North of the Russian Plain. Natural soil areas were calculated using a digital soil map. The analysis of changes in forest growing potential of soils is carried out from the beginning of intensive development of the territory to the modern period. These calculations can form the basis for assessing the potential contribution of the region to ensuring the reproduction of forest resources.

During World War II, representatives of almost all the Soviet Republics fought in partisan detachments in the occupied territory of the Leningrad Region. Among them were many representatives of the Central Asian republics: Kazakhstan, Kyrgyzstan and Uzbekistan. Many Leningrad citizens, including relatives of partisans, had been evacuated to Central Asia by that time. However, representatives of Asian workers’ collectives came to meet with the partisans. The huge distance, the difference in cultures and even completely different weather conditions did not become an obstacle to those patriots-Turkestanis who joined the resistance forces in the North-West of Russia.

Pinus sylvestris L. is the main tree species of forest ecosystems in the European North of Russia, therefore, in-depth studies of the diversity of forms and growth processes of this plant are important. Forms in pine stand out according to morphological and other characteristics. In conditions of prolonged excessive soil moisture, the joint growth of various forms of pine is observed. The aim of the work is to study the growth of various forms of pine according to morphostructural characteristics in the shrub-sphagnum forest type estuary of the Onega River. Investigations of tree growth (according to the form of seed cone scales apophysis and crown habit) were carried out in shrub-sphagnum pine forests of different ages in the north-west of the European part of Russia (northern taiga subzone). Morphometric measurements of the vegetative and generative spheres in the forms of scots pine were made. It is established that the advantage in morphometric characteristics, average values ​​of radial growth, late and early wood has a pine tree with a «convex» apophysis form. The advantage with respect to the morphometric characteristics of the trunk and crown is form with «ordinary» crown habit. The «ordinary» form has larger cones, a larger value of radial growth and macrostructural parameters of wood compared to the «swamp».

Long-term complex observations covering the period of 1949–2018 made possible to determine the average annual characteristics of the depth of freezing of wetlands in the North and Northwest of the European territory of Russia together with main factors of its formation, and spatial and temporal variability. The main factors that determine the depth of freezing of wetlands are ambient temperature, snow cover thickness, and a degree of watering of the micro landscape (water reserves of the micro landscape). At the initial stage of freezing, the major factor is the ambient temperature, when intensity of the freezing reaches 0.5–0.8 cm/day. As snow falls, the freezing rate becomes smaller, and when the snow cover thickness reaches 25–30 cm the depth amounts to 0.2–0.3 cm/day and smaller. It was found that the spatial variability of the freezing depth decreases from large values of the coefficient of variation (0.3–0.4) at the depth of 20–30 cm to less than 0.1 when the depth exceeds 60 cm. The largest values of the depth are recorded in the North of the Kola Peninsula, where sometimes they reach from 84 to 97 cm with the average values of 48–66. In large hummocky bogs, when the seasonal freezing comes down to 63–65 cm it links with the permafrost layer. On average, swamps of these bogs freeze down to a depth of 68 cm. The average climatic depth of freezing of oligotrophic bogs of the NorthWest is 21–24 cm; in some years, freezing of them reaches 32–40 cm. It has been shown that the relative warming of the climate resulted in decreasing in the depth of freezing of wetlands in the North and North-West of the European territory of Russia. Relative to the previous climatic period, the depth of frost penetration in the northern Ilasskoye bog decreased by 32%, and in north-western Lammin-Suo bog – by 31%.

Cultivation Techniques

The appearance of the first marketable root crops with a diameter of more than 50 mm, categorized as elite, in the North-West region of the Russian Federation, may already occur by the end of the third decade of June. The crop price during this period is at least twice the one during mass harvesting. The price depends on the product’s presence on the consumer’s market as well as on weather conditions in the regions of traditional suppliers. In some years, the price can differ by a factor of 3-4. By the time of mass harvesting using traditional technology, the number of elite root crops does not exceed 50%. In order to assess the effectiveness of the proposed early beets cultivation technology, the studies were carried out in the economic conditions of the farm, Leningrad region on the area of 3 hectares. According to the research results, the proposed technology allows to reach 3.3-fold increase of the root crops yield, which are to be sold fresh through the retail network, compared to the traditional one. The gross income using the proposed technology, calculated for sales prices of 2019, amounted to 384.6 thousand rub/ha against 125.2 thousand rub/ha using traditional cultivation techniques.

To plan agrotechnical measures in changing climate it is necessary to track the dynamics of spatial and temporal changes in agrometeorological factors. Late spring and early autumn frosts are a limiting factor for agricultural crop production. In general, such frosts are of the radiation type. To study the spatial and temporal characteristics of the radiation frosts distribution in the North-West region of Russia, data of daily observations of the standard meteorological network from 1966 to 2015 were used. The change over the time in the average number of days with radiation frosts was calculated for two 25-year periods: from 1966 to 1990 and from 1991 to 2015. Two zones of multidirectional change of the average number of days with radiation frosts in the period from 1991 to 2015 were revealed. The decrease in the average number of days with radiation frosts during this period was recorded at the weather stations of Vologda and Leningrad (except for the weather station Belogorka) and the meteorological station Velikie Luky (Pskov region). At the same time all the weather stations of this zone (with the exception of the Vyborg weather station) are characterized by the higher number of days with radiation frosts then the weather station of the other zone. The increase in the average number of days with radiation frosts during this period was noted at the weather stations of the Pskov, Novgorod, Kaliningrad regions and the weather station Belogorka (Leningrad region).

В статье представлена публикация пяти новых чашечных камней, относящихся к категории почитаемых природных объектов, найденных в 2016–2017 гг. на Карельском перешейке (Приозерский район Ленинградской области). Комплекс археологических памятников, в том числе чашечных камней, у д. Ольховка представляет собой уникальное явление, поскольку это крупнейшее скопление подобных объектов на Северо-Западе России. В ходе разведок 2016–2017 гг. были обнаружены еще пять ранее неизвестных камней с чашевидными углублениями. Новые находки чашечных камней указывают на то, что территория комплекса еще до конца не изучена. Имеются серьезные предпосылки для поиска новых памятников подобного типа. Необходимо признание всей территории локализации археологических объектов в данном районе единой охраняемой зоной. Комплекс должен быть сохранен как природно-исторический ансамбль, составляющий единое целое с окружающим ландшафтом. The paper reports on five new cup-marked stones referred to the category of natural features revered by people which were found on the Karelian Isthmus (Priozersky District, Leningrad Region) in 2016–2017. The complex of sites including cup-marked stones near the village of Ol’khovka is a unique phenomenon because it is the largest concentration of such features in the North-West of Russia. In the course of archaeological reconnaissance in 2016–2017 five more previously unknown cup-marked stones were discovered. New finds of cup-marked stones demonstrate that the area of the complex has not yet been studied comprehensively. It is essential to continue searching for new sites of this type. The district where archaeological features are located should be declared a single protected area. The complex should be preserved as a natural and historical ensemble fully integrated into the surrounding landscape.

Recently, an article was published in this journal (Hartz et al. 2012), presenting new data on the age of early ceramics in eastern Europe (in particular, the central Russian Plain) and discussing the issues related to the appearance of pottery (i.e. Neolithization) in this region, with wider implications of the results for northern Eurasia. I was one of the reviewers of this paper, which is acknowledged by the authors. However, despite my numerous remarks and comments, many of them were not taken into account. As a result, the work by Hartz et al. (2012) suffers from several flaws; here I point them out and briefly discuss the issue of the Neolithization of Eurasia.

Abstract In order to take into account the territorial differences of natural and economic conditions, to identify biological and ecological patterns, the agro-landscape and ecological zoning of natural forage lands (NFL) of the North-Western natural and economic region of the Russian Federation has been developed. The Karelian province occupies 23% of the area in the north of the Leningrad region, bordering Karelia and Finland. The Karelian province is located in the western part of the Middle Taiga zone, which is characterized by Eastern European Middle Taiga plains. Most of the area of the province (65%) is covered by forests. Agricultural land occupies only 4% of the total area of the province. Including arable land – 2%, hayfields and pastures – 1% each. The territory of the province is significantly moistened and swampy. Swamps occupy 11% of the area, under water – about 11%. Shrubs occupy 3% of the area of the province, other land – about 6%. The structure of NFL is dominated (53%) by normally moistened dry-grass grasslands on sod-podzolic soils. Fine-grained sweet-scented and finegrained grasslands with a large participation of various grasses are common. The yield of hay is 9–13 c/ha, feed is 70 c/ha. Grass-mixed grass and grass-sedge-mixed grass lowland and swampy meadows on swamp-podzolic soils occupy 44%. Grass stands with the dominance of the sod pike are common. Swampy depressions are occupied by large-seeded grass stands. The yield of hay is 10–15 c/ha, feed is 9–11 c/ha. The ecological state of the province’s landscapes is satisfactory-tense.

Abstract In 2001–2006, several experimental aspen plantations were established in the North-West of Russia (Leningrad region). Three in vitro propagated elite aspen (Populus tremula L.) clones from the Kostroma Forest Research Station were used as the planting stock for plantations. The planting plans of some experimental plantations were lost, which made it impossible to identify the genetic lineages. 13-years old unknown aspen clones demonstrated prominent growth rates, and reliably overtook natural aspen coppice. ISSR markers were used for fast and cheap restoring of the missing planting plan of the experimental aspen plantation under study; as a result, progenies of three elite aspen clones were recognized. The best fast-growing and stem rot resistant aspen clones was identified and called “Kostroma”.
