Abstract. Two fire affected soils have been studied using micromorphological methods. The objective of the paper is to assess and compare fire effects on micropedological organization of soils in a forest steppe zone of the Central Russia (Volga Basin, Togljatty city). Samples were collected in the green zone of Togljatti city. The results showed that both soils were rich in quartz, feldspar. Mica was highly present in soils affected by surface fires, while calcium carbonates were identified in the soils affected by crowns. The type of plasma is humus-clay, but the soil assemblage is plasma-silt with the prevalence of the silt. Angular and subangular grains are the most dominant in soil particulates. No evidence of intensive weathering was detected. There was a decreasing of the porosity in soils affected by fires as consequence of soil pores filled with ash and charcoal.

he effect of sowing multiple-nutrient mineral fertilizerapplication on spring wheat crops of the Astrid variety on gray forest soils of the forest-steppe zone was found. The study of the weather conditions of the growing season showed that the total amount of precipitation during the growing season was significantly lower than the average annual -158 mm as compared to 220 mm of the normal. The monthly rainfalls sharply differed from long-term ones; this had a significant impact on the formation of yield and grain quality. The application of NPK fertilizer and ammoni-um-phosphate-sulfate at a rate of 100 kg ha and ammoni-um phosphate fertilizer at a rate of 50 kg ha increased the yield of spring wheat grain by 8-66%, and the gluten con-tent in the variant with ammonium phosphate fertilizer at the level of 26-31% ascompared to 28% in the control. The payback of 1 kg of the primary nutrient of the fertilizers by grain yield gain was the highest against the background of NPK fertilizer and ammonium-phosphate-sulfate -55.0 and 40.8 kg, respectively. The protein content in wheat grain for in all fertilization variants ranged within 13.1-15.2% as compared to 13.7% in the unfertilized variant. The thou-sand-kernel weight as a result of obtaining high gains in the variants of sowing application ranged within 31.1-38.3 g; TKW below the control was in the variants with ammonium phosphate fertilizer and ammonium-phosphate-sulfate -31.1 and 33.4 g. The grain-unit belonged to Class 3 (no less than 730). It has been found that it is agronomically efficient when cultivating soft spring wheat in a temperately moist zone, on more arid years, on gray forest soils, when sowing, to apply NPK fertilizer and ammonium-phosphate-sulfate at a rate of 100 kg ha.

The implementation of potato potential yield (30-40 tons per hectare) in the forest-steppe zone of the Middle Volga is possible with the introduction of highly adapted varieties, the use of evidence-based farming cultivation. The authors studied the efficiency of promising new varieties of potatoes on gray forest soils in the Republic of Tatarstan. It was founded that when treating by calculated dozes of fertilizer potatoes of Rozhdestvenskiy, Impala, Sprint, Feloks, Red Skarlet varieties on gray forest soils of the Middle Volga steppe on average for three years the planned harvest tubers 40 or more tons per hectare was formed. The yield of Aroza, Nevskiy, Adretta varieties was 36,51-37,30 tons per hectare. In the more favorable moisture 2009 year, the high yields of tubers were formed by varieties: early-maturing Impala (58.35 tons per hectare), Red Skarlet (57.02 tons per hectare), Feloks (55.83 tons per hectare), middle-maturing Adretta (57,22 tons per hectare), Rozhdestvenskiy (56.13 tons per hectare). In drought 2010 year, in the application of irrigation higher yields of tubers formed early-maturing varieties: Sprint (21.52 tons per hectare), Red Skarlet (21.06 tons per hectare), Impala (20.59 tons per hectare) and Aroza (20.53 tons per hectare) and middle-maturing variety Nevskiy (21.74 tons per hectare). Less yields in 2010 were such varieties as Adretta - middle-maturing (14.58 tons per hectare) early-maturing Rokko (13.67 tons per hectare). The difference in yield of these varieties in this year reached 7.16 tons per hectare, the higher yield more than 20 tons per hectare was provided by 5 species of 9 studied (20,53-21,74 tons per hectare).

Steppificated oak forests — the unique relic natural complexes of the Eastern Europe remained in Central Russia by small fragments. These forests are important elements of forest-steppe natural complexes and the reserves of rare plant species. In the European scientific literature the questions of their syntaxonomy, features of structure and dynamics are discussed (Mucina at al., 1993; Chytrý, 1997; Chytrý, Horak, 1997; Roleček, 2005, 2007; Kevey, 2008; etc.). The data on phytocoenotic diversity of such forests in Central Russia were obtained only recently but they are fragmented and insufficient. According to the Braun-Blanquet approach these forests belong to the subcontinental forest-steppe alliance Aceri tatarici–Quercion Zólyomi 1957. Such forests are described within the areas of distribution of two important edificator species — Acer tataricum and A.campestre which the northeast areal border generally corresponds to the northeast border of the forest-steppe zone. On the basis of geobotanical data collected by the authors on the Middle-Russian Upland (Belgorod, Kursk, Tula regions) the 4 new associations within the alliance Aceri tatarici–Quercion Zólyomi 1957 are described. Floristic differentiation of new syntaxa from the Central-European syntaxa is demonstrated by the DCA-ordination. Authors propose an original combination of the diagnostic species for this alliance, for the area studied. Taking into account the floristic specificity of the forests of the region, we suggest uniting of the established associations into the new suballiance Crataego curvisepalae–Quercenion roboris. This alliance represents the East European mesoxerophyte broad-leaved (with Quercus robur) forests of forest-steppe zone of the Middle Russian subprovince of the East European forest-steppe province. The diagnostic species of the suballiance are following: Quercus robur, Acer platanoides, Chamaecytisus ruthenicus, Crataegus curvisepala, Frangula alnus, Melampyrum nemorosum, Sorbus aucuparia, Tilia cordata, Vibur­num opulus. The suballiance is diagnosed by absence of thermophilous ous Quercus species, in particular, Q.petraea, Q.pubescens, Q.cerris, etc., their hybrid forms, and also some Central European and Sub-Mediterranean trees and shrubs: Acer pseudoplatanus, Carpinus betulus, Crataegus laevigata, C.monogyna, Cornus mas, Fagus sylvatica, Ligustrum vulgare, Sorbus aria, S.tomentosa, Tilia argentea, T.plathyphyllos, Viburnum lantana, Ulmus minor. Results of the research spread our knowledge on distribution of the steppificatedbroad-leaved forests in the Central Russia. and geography of the alliance Aceri tatarici–Quercion in Eastern Europe.

Relevance. A study of the seasonal (phenological) phenomena and natural connections between them on the background of the relevant environmental conditions is of great scientific and practical interest. Knowledge of the dynamics of the seasonal development of woody plants helps in the selection of species and their assessment from an aesthetic and sanitary points of view, as well as in the development and implementation of measures to increase the sustainability of urban green spaces. Materials and methods. The purpose of these studies is to create a database of the dynamics of seasonal development of North American woody plants based on the results of many years of phenological monitoring (2003-2017). The 20 species and forms of North American woody introducers e of the VNIISPK arboretum genetic collection were the objects. Results. It was revealed that the growing season of woody North American plants corresponds to the climatic conditions of the forest-steppe zone of central Russia. The species with the earliest beginning of the growing season (the third decade of March) were distinguished. There were Mahonia pinnata, M. aquifolia, Betula lenta and B. lutea. On the basis of phenological calendars, phenological spectrums have been constructed. These consist of three lines (the development of leaves, shoots, flowers and fruits) with the corresponding color symbols. It has been revealed that phenospectrums vary depending on the conditions of the year. As a result, the database of 20 species and forms of North American woody plants was formed in the form of phenological spectrums against the background of registration of weather conditions in the forest-steppe zone of Russia. The database includes three options for the possible dynamics of the seasonal development of introduced North American plants. The created database allows observing, comparing, evaluating and forecasting changes in the seasonal rhythm of the studied species of introduced North American plants.
