FAO policy documents on the degraded soils improvement and the world's agro-soil resources co-evolution are discussed. The agrocenoses soil is considered as a product of natural soil co-evolution. The global, environment-forming and productive soil functions are analyzed. The urgency and importance of the soil improving in Russia are stated. The need to optimize and improve soil productivity and health through various management measures, in the first place - organic fertilizers, is emphasized. The adaptively integrated plant protection role in improving the agro-soils phytosanitary status and health is discussed.

The results of the assessment, soil-protective capacity of basic tillage soil are given. The highest anti-erosion effectiveness is provided by deep soil-free tillage, which facilitates the retention of surface runoff from stubble residues, as well as its transfer to the underlying layers of the soil profile due to increased water permeability of the soil. No-till soil tillage is more effective in autumn plowing with erosion from the meltwater runoff, when the frozen soil has low water permeability and is not occupied by vegetation, as well as on tilled, spring cereals, leguminous crops and annual grasses in the stream of rainfall. Unrefined surface treatments have less soil protection effect due to insufficient depth of loosening of the soil, leading to an increase in runoff due to compaction of the lower layers of the arable horizon.

As follows from six-year study the optimum doses of the polymer for sod-podzolic sandy soil treatment are 10 and 20 ppm. Their action time amounted to 3 and 4 years respectively and they allowed yield increase in summary over the duration of their action by 101,2 and 114,4 %. With total Kn derating of cesium-137 and strontium-90 by 91,3 – 99,5 %.

The analysis of winter soft wheat varieties included into the State register of varieties is done. The varieties rendering a complex of economic and useful parameters (yield, winter resistance, lodging and drought resistance, raw protein and cellulose content, baking estimate is done).

The analysis of the influence of tank mixtures of liquid mineral fertilizers and plant protection products on the reproduction of pests and the yield of cereals. The effectiveness of the carbamide-amine mixture (CAS) on the number of major phytophagous species of modern agrocenoses was determined. It is established that the use of liquid forms of mineral fertilizers in crop production meets the requirements of modern resourcesaving farming, since it provides both the demand of crops for nutrients and the expansion of reproduction of soil fertility, as well as the control of a complex of plant phytophages. However insufficiently studied are the issues of effective application of the mixture of CAS with the preparation of protection of cereals from a complex of pests at the main stages of organogenesis of cultivated plants.

The article presents the results of granaries arthropod fauna for the period of 2002–2014. It has been determined that in the structure of stock pest prevalence the largest share is made by mites (Acarina) – 82–94 % and insects from the beetles order (Coleoptera) – 5–16 %. The interrelation between the viability of mites and air temperature is revealed, which has served as a justification for the calculation of acaroindices, making it possible to predict their number and severity increase in the controlled batches of grain. The effectiveness and expediency of grain protection measures (mechanical cleaning, fumigation, wet and aerosol treatment with insecticides and insectoacaricides) is shown depending on the specific diversity of insects and mites, the purpose of the product, hermetic warehouse facilities. In connection with the climate warming, it is necessary to monitor stock pests, as well as to control the state of arthropod populations for resistance to pesticides.

The article presents the results of pest risk analysis (PRA) of five quarantine pests of stored grain: the groundnut borer (Caryedon gonagra Fabr.), the Mexican bean beetle (Zabrotes subfasciatus Boh.), the Chinese bruchid (Callosobruchus chinensis Linn.), the cowpea weevil (Callosobruchus maculatus Fabr.) and the khapra beetle (Trogoderma granarium Ev.) for сentral Ukraine. It was suggested to remove the groundnut borer from the list of regulated (quarantine) pests, while the remaining species should be preserved in the "List of regulated organisms" of А-1 List “Quarantine organisms absent in Ukraine”.

The results of the assessment of the resistance to corneed (a complex of soil pathogens) of 15 selection samples of red beet in the conditions of Belarus are presented. Sources for the selection of red beet for resistance to soil pathogens have been established.

Apple cultivars, selected as immune and resistant to apple scab and cultivated in commercial orchards, with time are losing this property and are being affected by the disease from slightlymoderate level on the cultivars with monogenic resistance (severity on leaves varies from 0,1 to 32,2 %, on fruits – from 0,1 to 23,0 %) up to epiphytotic – on polygenic resistant ones (severity on leaves – up to 58,7 %, on fruits – up to 68,0 %). Anthracnose cancer harmfulness on apple scab resistant cultivars has increased – the incidence in focuses can reach 71,4 %. Resistant apple cultivars are affected by the spot diseases complex on slightly – moderate level (incidence – up to 10,4 %) and brown rot (incidence – 2,6–15,2 %).

It is determined that in Belarus in the European cranberry bush plantations among the coleopterous pests the most spread is the European cranberry bush beetle – Pyrrhalta viburni (Paykull), the number of which reaches 55 larvae on 2 m shoots. There difference in colonization by the European cranberry bush beetle of regionalized varieties has not been noticed. The phytophage number by years of researches has varied depending on predatory insects number (bug Himacerus apterus F. from fam. Nabidae and predatory mites from fam. Phytoseiidae). By ratio of hibernating predator and phytophage stages 1:4, the European cranberry bush number is 12 times decreased. In honeysuckle among coleopterous pests rose stem girdler (Agrilus coerulescens Ratz.) is spread, damaging 13,7–16,1 % of the crop shoots. In red chokeberry plantations among coleopterous the most noxious is service-tree blossom beetle – Anthonomus conspersus Desb.). Buds severity by the phytophage makes 1,2–5,5 %.

The results of observations of long-term seasonal dynamics of life forms of harmful insects–phytophages on winter wheat crops - are obtained in the forest-steppe of Ukraine for the period 2014–2017. On the basis of their own research, it was suggested that monitoring insects be carried out in time to take into account the population size in order to determine the epo and trophic groups.

The article presents an analysis of the use of flax seeds and its components, from antiquity to the present. As part of the diet, Flaxseed has not only a function of energy, supplying energy and delivering plastic material to the body structure, but also ensures an improvement of our health and well-being, reduces the risk of certain diseases. By improving the nutritional profile of foods by reducing salt, sugar and saturated fats, as well as by increasing the content of omega-3 fatty acids and other bioactive compounds, flax seeds and its components contribute to the expansion of the assorted health food. In the drugstores of the Republic is currently available in various formulations from flax (linseed-oil, biological additives to food, flax meal, lignans, etc.) So the flax can be attributed both to medicines or functional food that plays a huge role in the prevention and treatment of several diseases.

As a result of the conducted researches, it is determined that the pumpkin oil output among the selection samples of the Belarusian selection solid- pumpkin has made 33,3–46,6 %. The content of unsaturated fatty acids predominates in oil (linoleic acid – 64,5 %, oleic – 17–19,7) in comparison with the saturated (palmitic – 8,5–10,7 % and stearic – 3,8–6 %). In pumpkin cake a high content of macro- and microelements is determined, the mass fraction of protein and amino acids is increased, but the mass fraction of fat is decreased.

The article presents the morphological and biological characteristics of a new variety Karunak of ornamental appletree, obtained from open pollination one form Malus x purpurea (Barbier) Rehd. The variety has a short juvenile period, it is resistant to a complex of leaf spots, winter-hardy, with annual abundant flowering and tree bearing. It has a long bright red blossom, anthocyanin color of leaves, which gives the foliage attractive appearance to the end of the leaf fall and attractive, non-falling purple fruit-berries that persist for most of the winter period without significant color changes.
