Abstract. The development of optimal nutritional system for agricultural crops is one of the main factors for the getting of stable yields. The deficiency of some macro- and microelements in plant nutrition, leading to yield decreasing, can be compensated with new complex of balanced fertilizers and biological products. The aim of the work is to study the effect of nitrogen fertilization, new forms of complex fertilizers based on active biological substances (“Kodamin B-Mo”, “K-Gumat-Na”, “Agroflorin” “Auksinolen”) and the microbiological preparation (MBP) “Bisolbifit” on the yield and quality of grain of fodder winter rye “Novaya Era” on sod-podzolic soils in the Pskov region. The originality is that for the agro-ecological conditions of the Pskov region, the influence of new complex fertilizers, biological and humic preparations in the cultivation of winter rye has been studied. Methods. The research was carried out in 2019 on the experimental field of the laboratory of agricultural technologies of the Federal research center for Bast Crops (Pskov Department). The records, observations and analyzes were carried out according to generally accepted methods. Results. The maximal positive effect on grain yield was made with the introduction of complete mineral fertilizer in doses of N80P40K70 with fractional nitrogen application: 20 kg of active substance – in the main fertilizer, 40 kg – in the tillering phase and 20 kg – in the booting phase. Up to 1,3 t/ha or 42.2 % to the control level were obtained in that variation. Application of mineral fertilizers in a dose of N40P40K70 and MBP “Bisolbifit” increased on 0,4 t/ha of grain, which amounted 10.6 %. Foliar double treatment of plants with fertilizer “Kodamin B-Mo” increased grain yield up to 8.6 %. The influence of the investigated factors on the protein content and nitrate nitrogen in plants of fodder winter rye, the weight of 1000 seeds and the structure of the yield was established. For 1 kg of active substance of mineral fertilizers at various doses of nitrogen fertilizing the additional yield of grain from 3.68 to 6.39 kg was obtained.

The purpose of the study is to identify the effectiveness of various types of fertilizers and biologics Bisolbifit on the yield and quality indicators of spring barley grain. Experiments were conducted in 2015-2017 in Ulyanovsk region. The soil of the experimental site is represented by leached Chernozem, heavy loam. The scheme of experience included two factors. Factor A-control; pre-sowing seed treatment with Bisolbifit; NPK in pure form at a dose of 15 kg of active substance per hectare; modified NPK (NPKm) at a dose of 15 kg of active substance per hectare; modified NPK (1/2 NPKm) at a dose of 7.5 kg of active substance per hectare. Factor B (background): zero-without fertilizers; pure ammonium nitrate (NH4NO3) at a dose of 40 kg of active substance per hectare; modified ammonium nitrate (1/2 NH4NO3m) at a dose of 20 kg of active substance per hectare. Inoculation of seeds with a biological preparation was performed by semi-dry etching 1...2 days before sowing at a dose of 400...600 g per hectare of seeds. For the preparation of modified NPK and ammonium nitrate, the biological preparation Bisolbifit was used in a dose of 4 kg per 1 ton of fertilizers. The drug was applied to mineral fertilizer granules on the day of sowing. All types of fertilizers and biologics studied led to an increase in yield. The use of mineral fertilizers in pure form (untreated with biologics) increased the yield by 0.26...0.41 t/ha, modified – by 0.38...0.54 t/ha, biologics – by 0.06...0.19 t/ha, compared with the control (2.67 t/ha). The use of fertilizers and biologics increased the weight of 1000 grains – the best options were with modified NPK at a dose of 15 kg d. V./ha-49.4...53.0 g. the quality indicators of the studied agricultural practices did not have a significant impact. The highest payback of fertilizers by increasing the yield was recorded in the variant with pre-sowing treatment of seeds with Bisolbifit biologics and amounted to 7.7...11.4 kg/kg

Maize Fertilization

The response of crops to the application of biofertilizers in the soil is not yet well established. Therefore, we carried out this study with the objective of evaluating the productive potential of maize fertilized with doses of sewage sludge, comparing with the use of mineral fertilizer over four agricultural seasons. The experiment was conducted in a Red Dystroferric Nitosol (Ultisol) in a randomized block design and repeated measures in time. The treatments consisted of five doses of sewage sludge and one treatment using nitrogen, phosphorus and potassium in formulation. All fertilizations were carried out at maize sowing at four planting times (summer and 2nd crop of 1st agricultural year and, summer and 2nd crop of 2nd agricultural year) and replicates. The results showed a cumulative increase in the P, Ca, Mg and Zn leaf concentrations over the four seasons crops, when the sewage sludge was used in the 30 and 40 Mg ha-1 doses. However, reductions in plant height, weight and maize cob diameter, mass and grain yield were observed at the end of the last harvest. The treated sewage sludge is a viable alternative for maize fertilization in the first harvest, provides increases in grain yield in the order of 1.35 Mg ha-1 and can be recommended instead of NPK mineral fertilizers in built-up fertility soils.

Integrated Nutrient Management

Integrated nutrient management (INM) effects chemical transformation of nutrients in soil and plant uptake. This study present the long-term (30 years) effects of integrated nutrient management on zinc (Zn) fractions and rice yield. The treatments include ten combinations of nitrogen, phosphorous and potassium applied through mineral fertilizers and substituted through farmyard manure (FYM), green manure (GM) and wheat cut straw (WCS).The distribution of Zn into exchangeable (EXCH), carbonate bound (CARB), organic matter bound (OM), manganese oxides bound (MnOX), amorphous iron oxide bound (AFeOX) and crystalline iron oxide bound (CFeOX) was determined. The effect of long-term use of mineral fertilizers on EXCH-Zn was not significant as compared to control, however, EXCH-Zn increased significantly in INM treatments compared to both control and mineral fertilizer in surface soil (0-15 cm). Similarly, CARB-Zn and OM-Zn was significantly higher in INM as compared to control and mineral fertilizer treatments. The distribution of Zn in MnOX, AFeOX and CFeOX fractions was not distinctly affected with long-term fertilizations. In general, concentration of Zn fractions was lower in subsurface soils (15-30 cm) as compared to surface soils. The grain yield of rice increased in order control< mineral fertilizers <INM treatments. The highest grain yield (71.8 q ha-1) was recorded in INM treatment where 25% of the recommended NPK were supplied through GM. The positive and significant correlation of EXCH-Zn (r = 0.714), CARB-Zn (r = 0.601) and OM-Zn(r = 0.648) fractions and Zn uptake in grain showed that the plant availability of Zn depends upon these fractions in soils.

The results of the influence of pre-sowing seed treatment, the main application of mineral fertilizers and foliar fertilizing with ammonium nitrate, urea, organo-mineral fertilizer D2 or bacterial preparation Escort-bio on the formation of productivity and quality of spring wheat of the Elegia mironovskaya variety are presented. Experimental investigations were carried out on the Chernozem of the South during 2014-2016. In the conditions of the educational, scientific and practical center of the Nikolaev NAU. The results of research showed that the introduction of nitrogen-phosphorus fertilizers before sowing and foliar fertilizing of spring wheat crops on average over three years provided an increase in grain yield by 1.00–1.58 t/ha in variants with water treatment of seeds and by 1.08–1.72 t/ha when processing seeds with microbial preparation Escort-bio. Pre-sowing treatment of escort-bio seeds contributed to the additional production of 0.14–0.28 t /ha of grain, depending on the fertilizer option. The highest grain yield was formed by applying N30P30 for pre-sowing cultivation, treating seeds with a microbial preparation and carrying out the phase of plant exit into the tube of feeding with ammonium nitrate with a dose of N30. Pre-sowing treatment of escort-bio seeds and foliar fertilizing contributed to an increase in the payback of fertilizers by increasing the yield of spring wheat. The maximum specified indicator is determined by the background of bacterial seed treatment, the main application to the sowing of N30P30 and carrying out two top-UPS with organo-mineral fertilizer D2 or Escort-bio. Application of fertilizers and foliar top-UPS on average over three years increased the protein content of spring wheat by 0.7–1.4 %, and gluten – by 1.2–1.9 %. The maximum both indicators of grain quality are determined in the version of the main application of N30P30 with making-up at the beginning of the earing phase with urea at a dose of N30 –14.9 and 28.1 %. The conditional yield of protein and gluten from a hectare of spring wheat sowing with an improvement in the background of plant nutrition grew and reached maximum values in the variants of N60P30 before sowing or N30P30 before sowing with fertilizing with ammonium nitrate at a dose of N30 in the phase of exit to the tube.

Soybean is the most commercially cultivated crop in Paraguay, and obtaining high yields requires the application of large amounts of fertilizers, raising the cost of production. Developing strategies for the efficient use of applied nutrients is necessary. Therefore, the study aimed to evaluate the agronomic efficiency of combinations of mineral fertilizers with organic matter and rock powder in the development, nutrition, and yield of soybean. The experiment was carried out in Hernandarias, Paraguay, in the 2016-2017 harvest. The different fertilizers influenced the absorption of Zn, Mg and K, and grain yield. Among the treatments, the highlight was the agronomic efficiency index obtained by the replacement of 30% of mineral fertilizer by humus, presenting grain yield of 3219, 67 kg ha-1. However, it was equal to the mixing 30% of humus + rock powder with 70% of NPK formulation 04:40:10 with grain yield of 3206.50 kg ha-1, and the mixing 20% of humus + rock powder with 80% of NPK formulation 04:40:10 with grain yield of 3165.17 kg ha-1. Thus, it is recommended to use rock powder and humus in soybean production in Paraguay, especially in Latossolos (Oxisols) that have little organic matter and low CTC.

The research aims to establish the eff ectiveness of granular chalk use produced by «Slavuta-Calcium» Ltd. under growing Poliska–90 winter wheat variety, changing the physicochemical properties of grey forest soil and the wheat productivity. It also aims to establish optimal dosis of «Slavuta-Calcium» granular chalk as the meliorant and mineral fertilizer for grey forest soil in the system of winter wheat fertilization. In the temporary fi eld studies, various doses of nutrients N60–90–120P30–45–60K60–90–120 combined with «Slavuta–Calcium» granular chalk in a dose of Ca230–460–690 kg/ha of the active substance were studied against the background of secondary plowing of rotation products – soybean biomass that averaged 2.34 t/ha. Granular chalk is a modern complex highly eff ective meliorant with the content of Ca – 37.7 and Mg – 0.2 %, the mass fraction of carbonates (CaCO3 + MgCO3) makes at least 95 %. It is characterized by a high level of solubility when interacting with moisture in soil. It has a form of white granules, the mass fraction of 4.0–6.0 mm in size granules makes not less than 90 % and the one of 1.0 mm in size makes less than 5 %. Reactivity – 97 %. The granular chalk is advisable to apply on acidic soils, as a highly concentrated calcium-magnesium fertilizer, with the former as the dominant fertilizer, to optimize the physicochemical properties of the soil, as well as the plant nutrition system, in particular, increasing the availability of an element for assimilation by plants and as long-term ameliorants. The eff ectiveness of the use of mineral fertilizers, in particular acidic nitrogen on highly and medium acidic soils, after chemical reclamation is increased by 30–50 %, and slightly acidic by 15–20 %. The increase in productivity of crops from the combined eff ects of nutrients and chalk granulated is usually higher than when separately applied. The eff ectiveness of the integrated action of these elements is manifested in the growth of plant productivity and the quality of the resulting products, as well as the optimization of physical chemical properties and soil buff ering in the long term. In order to optimize the physicochemical properties of the arable layer of gray forest soil and the productive nutrition of agricultural crops, winter wheat, in particular, biogenic elements should be used in doses N60-90-120P30-45- 60K60-90-120 with granulated chalk «Slavuta-Calcium» in doses of Ca230-460-690 kg/ha of active substance. Granulated chalk obtained as a result of industrial grinding of solid sedimentary carbonate rocks of natural origin, subsequently under the infl uence of the granulation process of the starting material contains Ca and Mg carbonates of at least 95 %, dense granules which facilitates convenient mechanized application, as well as chalk suitable for accurate metered application on the quest map. Key words: granular chalk, gray forest soil, chemical reclamation, crop productivity.
