Producers of agricultural plants are increasingly marking a decrease in the responsiveness of cultivated plants to the mineral fertilizers applied to the soil. The explanation of this phenomenon can be the shift of limiting factors that determine the yield from mineral components in the soil to substances of organic and biological origin. The paper presents comparative data of the influence of mineral and organic fertilizer system on main biological indicators of the soil – nitrogen transforming groups of microorganisms, total microbial number (TMN), and soil respiration. The change in total and mineral nitrogen in the soil is estimated. The novelty of the study is that organic fertilizers are used in amounts comparable to the doses of mineral fertilizers in physical weight – 200 kg/ha. The application is carried out locally simultaneously with the seeding. As a result of the analysis, it has been found that ammonifiers (by 20.0–45 %), nitrifiers (by 30.0–46.7 %) numerically dominate in soil with organic fertilizers under all crops (corn, sunflower, soybean, sugar beet), the total microbial number is higher by 24.6–48.3 %. The intensity of carbon dioxide emissions (soil respiration) is also higher by 19.0–45.6 %. The intensity of biogeochemical processes in the soil and the related transformations of mineral nutrients, respectively and the provision of plants with them closely correlates with the number of valuable groups of microorganisms. The correlation coefficient between the number of ammonifiers and nitrifiers with the total nitrogen content in the soil under all studied crops in an organic fertilizer system is r=0.93.

Producers of agricultural plant products are increasingly reporting a decrease in the responsiveness of cultivated plants to the mineral fertilizers applied to the soil. The explanation of this phenomenon can be the shift of limiting factors that determine the yield from the mineral components in the soil to substances of organic and biological origin. In the present work, comparative data are presented on the influence of mineral and organic fertilizer systems on the main biological indicators of the soil - nitrogen transforming groups of microorganisms, total microbial number (TMM), soil respiration. The change in total and mineral nitrogen in the soil is assessed. The novelty of the study is that organic fertilizers are used in amounts comparable to the doses of mineral fertilizers in physical weight - 200 kg per hectare. The application is carried out locally simultaneously with the seeding. As a result of the analysis, it was found that in soil with organic fertilizers under all crops (corn, sunflower, soybeans, sugar beets), ammonificators (20.0-45%) numerically dominate, nitrifiers (30.0-46.7% ), the total microbial number is higher by 24.6-48.3%. The intensity of carbon dioxide emissions (soil respiration) is also higher by 19.0-45.6%. The intensity of biogeochemical processes in the soil and the associated transformations of mineral nutrients, respectively, and the provision of plants with them closely correlates with the number of agronomically valuable groups of microorganisms. The correlation coefficient between the number of ammonifiers and nitrifiers with the total nitrogen content in the soil under all the studied crops on an organic fertilizer system is r = 0.93.

The experiment assessed the influence of various biofertilizers and biostimulants on the growth characteristics of the root system, its colonization by arbuscular mycorrhizal fungi and the yielding of sweet cherry trees in field conditions. The experiment, conducted in Pomological Orchard of Research Institute of Horticulture located in Skierniewice during 2011–2014, involved the use of a mycorrhizal substrate, organic fertilizers and biostimulant in randomised block design. The control combination consisted of plants fertilized with mineral fertilizers (NPK). The use of the organic fertilizer BF Ekomix in dose 100 g per tree each year in the spring significantly increased the number of root tips in comparison with the control trees. There was also a tendency for the roots to lengthen and increase their surface area under the influence of this biofertilizer. In addition, the inoculation of roots with the mycorrhizal substrate in dose 200 g per tree per year stimulated the colonization of the roots of sweet cherry trees by arbuscular mycorrhizal fungi, which in turn led to improved root growth parameters.

Исследования проводились на дерновоподзолистой среднесуглинистой почве нормального увлажнения. В опыте изучалось влияние органических и минеральных удобрений в разной дозе на видовой состав сорных растений в посевах и урожайность зелёной массы кукурузы. Применение в посевах кукурузы органоминеральных удобрений с полной и сниженной дозой привело к уменьшению доли участия многолетних видов на 11,1 и 11,5 соответственно, в сравнении с контролем. На данных фонах наблюдалось снижение доли участия пырея ползучего на 5,26,7, осота полевого на 2,83,5, бодяка полевого на 1,53,5, повышение доли участия чистеца болотного на 1,6. Внесение органических удобрений (сидератов, укосов многолетних трав) способствовало повышению доли многолетников на 13,3 в сравнении с контролем. С использованием органической системы земледелия на посевах кукурузы увеличивается доля участия хвоща полевого на 5,6, чистеца болотного на 4,2, осота полевого на 3,7, пырея ползучего на 3,2 снижается доля участия бодяка полевого на 3,6. Наибольшее число видов малолетних сорных растений (11 видов) отмечалось при внесении органоминеральных удобрений с полной дозой. Органическая система земледелия способствовала увеличению доли участия звездчатки средней, дымянки аптечной, яснотки пурпуровой, незабудки полевой, пикульника красивого и снижению доли мари белой, горцев. Урожайность зелёной массы кукурузы повышалась при внесении органоминеральных удобрений в полной дозе на 419 ц/га в сравнении с контролем.Researches were carried out on soddy podzolic medium loamy soil of normal moisture. The trial studied the effect of organic and mineral fertilizers in different doses on the species composition of weedage in sowings and the yield of green mass of corn. The use of organic fertilizer with full and reduced dose in corn sowings led to a decrease in the share of participation of perennial species by 11.1 and 11.5 respectively in comparison with the control. On these backgrounds there was a decrease in the share of participation of couch grass by 5.26.7, field milk thistle by 2.83.5, cursed thistle by 1.53.5, and the increase in the share of clowns woundwort by 1.6. The application of organic fertilizers (green manure, perennial grass cuttings) contributed to an increase in the share of perennials by 13.3 compared with the control. With the use of organic farming on corn sowings the share of participation of bottle brush increased by 5.6, clowns woundwort by 4.2, field milk thistle by 3.7, couch grass by 3.2 the share of participation of the cursed thistle decreases by 3.6. The largest number of species of very yuong weed plants (11 species) was observed when organic fertilizers were applied with a full dose. The organic farming system contributed to an increase in the share of participation of chickweed satin flower, drug fumitory, rabbitmeat, field scorpion grass, bee nettle and a decrease in the proportion of Chenopodium album and pepper plants. The yield of green mass of corn increased with the introduction of organic fertilizers in the full dose of 419 centner/ha in comparison with the control.

Barley is a crop, requires the availability of available nutrients in the soil, especially at the be-ginning of the growing season. The aim of the research was to determine the effectiveness of the aftereffect of using vermicompost when growing spring barley on different backgrounds in the Donetsk region. The studies were carried out according to the methodology of the field experiment of B. A. Dospehova. Research methods: field, supplemented by analytical studies, measurements, calculations and observations. The studies were conducted in 2017–2019 by laboratory-field method in field crop rotation in the experimental sections of the Donetsk SSES NAAS. The repetition in the experiments is 3-fold. The location of the plots is systematic. The soil is alkaline-chernozemic carbonate, having an average supply of mineral nitrogen and mobile phosphorus, low – potassium. The humus content of 4,2 % indicates a high potential soil fertility, but to realize the potential of the culture, additional application of phosphorus-potassium fertilizers is necessary. The technology for growing crops is generally accepted for the farms of the region, with the ex- ception of the factors studied. Variety of barley spring Avers. The experience scheme provides for: control (without fertilizers); background – saturation of crop rotation with vermicompost granular 2 t/ha; background + N30P30K30; background + N60P60K60; N30P30K30. The use of organic fertilizers under the predecessor in crop rotation provided improve nutriti-on conditions for plants, which positively affected the growth and development of spring barley plants. So, on the variants with the use of mineral fertilizers, the highest indices of the number of productive stems and the structure of the crop were noted in the background. The variant where N60P60K60 was added in the background produced the largest mass of 1000 grains – 49,8 g, which is 4,6 % higher than the control. Analysis of the study indicates the positive effect of the aftereffect of organic fertilizer (ver-micompost) on the yield of spring barley. The maximum yield of spring barley was obtained against the background of aftereffect of vermicompost 2 t/ha and the application of mineral fertilizers N60P60K60 – 5,05 t/ha, but due to high production costs, the profitability level is 114,9 %. The application of organic fertilizers under the background provides a yield of 3,67 t/ha and the highest level of profitability of 140,6 %. The optimal technological option provides for the introduction of mineral fertilizers in the norm N30P30K30 amid predecessor saturation with vermicompost. This allows increasing the yield up to 4,90 t/ha (by 1,46 t/ha or 42,4 % to the control) and obtaining a profitability level of 136,1 %. The use only of mineral fertilizer N30P30K30 in severely arid weather conditions of the steppe zone allows increasing the yield by 0,70 t/ha compared to the control but, due to the high cost of pro-duction, leads to a low production profitability of 99,6 %. Key words: spring barley, background, vermicompost, mineral fertilizers, yield, economic effici-ency.

В данной статье рассматриваются вопросы влияния биологических и минеральных удобрений на продуктивность озимой ржи на темно-серой лесной почве в условиях Рязанской области. Исследования проводились по методу расщепленных делянок: на делянках первого порядка на озимой ржи изучали эффективность минеральных и органических удобрений, а на делянках второго порядка – действие биопрепаратов. Результаты исследований показали, что наилучшим из исследованных агроэкологических приемов повышения урожайности озимой ржи является использование в качестве органического удобрения соломы люпина и инокуляции семян биопрепаратами ризоагрин или флавобактерин. Урожайность зерна озимой ржи составляет от 37,5 ц/га при использовании ризоагрина и до 38,7 ц/га – флавобактерина, в среднем за 3 года. Относительно фона прибавка составляет 6,7 и 7,9 ц/га или 21,9 и 25,5%. При данном агротехнологическом приеме прибавка получена как за счет увеличения продуктивных стеблей с 495 ш/м2 до 521 шт/м2 при обработке ризоагрином и 538 шт/м2 при обработке флавобактерином, так и за счет увеличения массы зерна в колосе (35,1 г на контроле, 37,5 г при обработке ризоагрином и 37,7 г флавобактерином). Необходимо отметить, что этот максимальный уровень урожайности в опыте был достигнут без внесения минеральных азотных удобрений. В целом наблюдается прямая корреляция между содержанием азота и урожайностью озимой ржи. Вынос основных элементов питания возрастает с увеличением урожайности. This article discusses the impact of biological and mineral fertilizers on the productivity of winter rye on dark gray forest soil in the Ryazan region. Studies were carried out by the method of split plots: on plots of the first order on winter rye studied the effectiveness of mineral and organic fertilizers, and on plots of the second order-the effect of biological products. The results of the research showed that the best of the studied agroecological methods of increasing the yield of winter rye is the use of Lupin straw as an organic fertilizer and inoculation of seeds with biologics rizoagrin or flavobacterin. The yield of winter rye grain is from 37.5 C / ha using rhizoagrin and up to 38.7 C / ha from flavobacterin, on average for 3 years. Relative to the background, the increase is 6.7 and 7.9 C / ha or 21.9 and 25.5%. With this agrotechnological method, the increase was obtained both by increasing the productive stems from 495 W / m2 to 521 PCs/m2 when treated with rizoagrin and 538 PCs/m2 when treated with flavobacterin, and by increasing the weight of grain in the ear (35.1 g on the control, 37.5 g when treated with rizoagrin and 37.7 g flavobacterin). It should be noted that this maximum level of yield in the experiment was achieved without the introduction of mineral nitrogen fertilizers. In General, there is a direct correlation between nitrogen content and winter rye yield. The removal of essential nutrients increases with increasing yields.

Sustainable agricultural development depends mainly on the recycling of organic wastes to reduce environmental pollution, as well as to reduce the use of mineral fertilizers. Expired milk products are rich in organic carbon and nitrogen, so they are good raw materials for making organic fertilizers. In this study, expired milk products were converted to organic fertilizer (EDPF) by gravity and thermal treatments. The extracted EDPF was used in the nutrition of Williams banana plants under field conditions for two growing seasons. The field experiment consisted of four treatments including: C = control without N fertilization, U = traditional urea, SRU = slow-release urea, and EDPF. EDPF significantly (p < 0.05) improved the growth and yield of Williams banana in comparison to U and SRU. EDPF significantly minimized the soil pH and increased the soil organic-C and cation exchange capacity compared to the other treatments. EDPF increased the total yield of bunches by 20% and 17% in the first and second years, respectively, above U and SRU. EDPF surpassed the traditional and slow-release urea in its ability to supply the banana plants with nitrogen. NH3-N loss from U, SRU, and EDPF reached 172, 132, and 100 kg N ha−1, respectively, which accounted for 34%, 26%, and 20% of the total added nitrogen. Nitrogen loss from the investigated treatments was in the order: U > SRU > EDPF > C. EDPF significantly reduced the ammonia volatilization compared to U and SRU by reducing the soil pH and increasing the soil organic matter. The dynamic of NH3 emissions not only depends on the nitrogen form but also on climatic conditions and concentrations of NH4+ in the soil solution. Protecting the ecosystem and maximizing the benefits of wastes utilization can be done through the recycling of expired dairy products to organic fertilizers.
