The effect of new biologically pure organic fertilizers, Dia Guma and Gumi Turf, on the yield and quality of grape seedlings on nutrient-poor soils has been studied. The positive effect of silicon - organic fertilizer Dia Gum in combination with the growth stimulator Zircon on the survival rate of shanks, the formation of the aboveground part and the root system of plants is shown (the survival rate of shanks in relation to the control (pure water) increases almost 2 times from 36 to 70%, the diameter of growth - from 4.3 to 7 mm, total growth - from 32 to 54 cm, the volume of the root system - from 15 to 25 cm3). The use of peat - sapropel concentrate Gumi Peat in combination with the growth stimulator Zircon, according to the results of the yield and quality of the planting material, is close to the use of Dia Guma + Zircon. These fertilizers allow to a greater extent to biologize the process of growing planting material in the nursery.

The aim of the research is to study the method of vegetative propagation by cuttings to obtain a viable planting material of sawara cypress with a closed root system in the conditions of the Orel region. The study was carried out in 2019 at the private farm by Bykov L.S., Trosnyansky district, Orel region, in a cold closed ground, represented by gray forest medium loamy soils. Reproduction of the introduced species was carried out by rooting lignified cuttings in a nutrient substrate, which was prepared on the basis of neutralized peat with an acidity of 5.0 to 6.0 pH with the addition of perlite in a ratio of 4 to 1. Cuttings for the first group were cut on April 15 (before the beginning of the growing season), and for the second – on 16 May 2019 (after the beginning of the growing season) early in the morning from one mother plant, when the shoots are maximally saturated with moisture. Then the cuttings were planted in cassettes of 160 cells with an area of 0.24 m2 /piece to a depth of 2-3 cm and placed in an unheated protected ground with periodic watering. The best result for cuttings in the control group, harvested in mid-April (before the beginning of the growing season) – 96%, and for cuttings cut in mid-May (after the beginning of the growing season) – 60%. The mass of roots in established spring cuttings does not depend on the timing of reproduction, both variants showed an average weight of one root – 1.1 g. The profitability of the production of sawara cypress seedlings in the control group (when harvesting cuttings before vegetation) is 75%, which is 20% more than in seedlings grown from cuttings harvested after the beginning of the growing season.

The object of our research was one of the most common orchids in the world – Cypripedium calceolus L. As a rare species, it is listed in the Red book of the Russian Federation (3 category of rarity) [8], the Kirov region (3 category of rarity) [9], as well as in the Red books of 59 regions of the Russian Federation [2]. Limiting factors in the Kirov region are the violation of habitats as a result of anthropogenic impacts – deforestation, recreation, collection for bouquets, digging, reducing the number of species. Studies on the study of C. calceolus in the Kirov region are isolated [10–12]. The purpose of this work is to identify phytocenotic parameters and environmental conditions of C. calceolus habitats within the southern taiga fragment of the range. Studies of ecological and cenotic conditions of C. calceolus habitats were conducted in southern taiga forest ecosystems within the Kirov region (Slobodskaya, Afanasyevsky districts) (See table 1) in the period from 2012 to 2019. The studied habitats of C. calceolus are confined to non-morally-boreal-small-grass and grass spruce forests (Melico nutantis-Piceetum abietis subass. typicum, Maianthemo-Piceetum subass. typicum var. typical) (See fig. 1), pine trees with fir and spruce of various grasses (Melico nutantis-Pinetum sylvestris var. Lathyrus vernus). The growth of C. calceolus on the technogenically disturbed substrate of an old spent limestone quarry overgrown with coniferous rocks and various grasses was also noted. All the studied biotopes are characterized by a large constancy of non-moral species with not significant coverage of mosses. The stand of spruce forest types is dominated by Picea abies, pine-Pinus sylvestris. Abies sibirica occurs as an impurity. The undergrowth layer has a diverse species composition: Sorbus aucuparia, Frangula alnus, Lonicera xylosteum, Yuniperus communis, Daphne mezereum. In this tier of most studied phytocenoses there is a Atragene sibirica. The grass-shrub layer is also very diverse, which determines the high specificity of these communities. In addition to species of boreal small grass (Maianthemum bifolium, Orthilia secunda, Luzula pilosa, Rubus saxatilis), the presence of non – morals is characteristic-Lathyrus vernus, Melica nutans, Stellaria holostea, Asarum europaeum. Moss-lichen layer is fragmentary (covering up to 45 %), Pleurozium schreberi and Hylocomium splendens act as sodominants. Phyto-indication of the studied C. calceolus habitats according to ten ecological scales of D. N. Tsyganov (See table 2, Fig. 2) showed that in relation to the complex of all environmental factors, the studied species is mesovalent (MV) (It total = 0.54) and has an average level of lability in relation to the studied environmental factors. In relation to the complex of all environmental factors, C. calceolus is a mesobiont species. On a scale of soil acidity, the species is semistarvation at termokhimicheskie and apolitically scale and dial illumination-shading – metavalent on the scale of the wealth of the soil nitrogen – hemimillennial at createmotions scale and the scale of continentality of the climate avivamento. Only on the scale of soil moisture and the scale of soil salt regime, C. calceolus is stenovalent, which indicates a very limited range of possible habitats for this factor. The species, in the studied habitats, realizes from 4.61 to 23.84 % of its potential according to the studied factors. For C. calceolus, the results obtained allow us to extend the scale of soil acidity by 0.75 degrees to the right. According to the other scales, the values of the ecological space of the studied CP are placed in the ranges given by D. N. Tsyganov for this type Edaphic conditions of C. calceolus on the scale of soil moisture correspond to regimes from dry-saline to wet-forest-saline; on the factor of soil salt regime-poor soils; soil acidity – acidic-slightly acidic soils; soil richness in nitrogen – nitrogen – poor soils; moisture variability-soils with relatively stable and poorly variable moisture.

Growing environmental problems and increasing requirements of green jobs force universities around the world not only to transform their curricula but also to enrich existing ones with contents related to the promotion of sustainable development. This paper aims to show the importance of measuring and monitoring the share of green contents in all university activities, as only in that way it is possible to monitor trends and give realistic assessments of their effect and importance. The paper presents a comparative analysis of different types of methodologies for assessing sustainable activities at universities as well as research conducted at the University of Novi Sad in Serbia and its comparison with the University of Gothenburg (Sweden). This research aims to point out the importance of increasing competitiveness in higher education through assessment of green content in a curriculum and its promotion. In this way, through eco-labeling methodology, it would be easier to identify those contents that, in a certain share, contribute to the promotion of sustainable development. Furthermore, this methodology can easily be extended across the country and the region, which would bring positive effects to all stakeholders in higher education.
