The Impact

The purpose of the article – to perform comparative analysis of the economic effectiveness of the 10 samples of organic fertilizer of pig farm, bio humus “Humivit” and mineral fertilizers (Nitroamofoska, ammonium nitrate, carbamide) on the example of oats. The study used the following methods: abstract-logical, cash-analytical, cash-equivalent, expert, monographic. The research was done in Ukraine. The results of the comparative analysis of economic effectiveness of the 10 samples of organic pig fertilizer, bio humus “Humivit” and mineral fertilizers (Nitroamofoska, ammonium nitrate, carbamide) in the example of oats on the green mass show that the use of organic fertilizers sample number 1, 2, 3, 4, 5, 6, 10 is an economically effective, while organic fertilizers of sample number 7, 8, 9 are economically inefficient. By the main indicators of economic effectiveness (coefficients of payback, conditional additional profit, level of profitability) organic fertilizers sample number 1, 2, 3, 4, 5, 6, 10 have significant competitive advantages over the studied brands of mineral fertilizers and bio humus “Humivit”. The use of organic pig fertilizers, except the sample number 8, in economic terms for the impact on potential soil fertility is more effective than bio humus “Humivit”. The most significant economic benefits for the impact on potential soil fertility are samples of organic fertilizers pig number 1, 5, 10, whose application generates the lowest cost price of humus. The element of novelty is that with using the author’s scientific and methodical approach it was conducted the estimation of economic effectiveness of the liquid organic fertilizer of pig farm for the impact on potential soil fertility.

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.

The issue of scientifically sound fertilizer application in fruit plantations, which are long-term and re-grown in one place remains insufficiently studied. To solve this problem is possible only in long-term stationary studies, as the impact of different fertilizer systems on changes in soil properties and tree productivity for a long period of their use. The results of researches of long-term fertilizer influence on the main fertility indices of dark gray podzolic heavy loam soil and productivity of repeatedly grown apple trees of Idared varieties on seed and vegetative (M4) rootstocks and Calville snow on seedling rootstock are considered. During the 85-year period of growing the first and second generation of apple trees in the experimental garden, the organic fertilizer (40 t/ha of cattle manure), mineral fertilizer (N120P120K120) and their combination (20 t/ha of manure + N60P60K60) were applied in the old plantation every two years in autumn in plowing in rows at 18–20 cm, and in the new repetition: manure, phosphorus and potassium fertilizers as well, and nitrogen fertilizer in half doses annually in spring for cultivation or disk plowing to a depth of 12–15 cm. As a result of research it was found that organic fertilizer better than mineral fertilizers provided the formation of soil fertility (humus and mobile compounds and forms of nutrients, soil reaction) and yield capacity of experimental apple trees, which for all years of fruiting exceeded the total yield of Calville snow and Idared on seedling and vegetative rootstocks, respectively, by 34.8, 27.7 and 23.4 % compared with the yield of the control non-fertilized areas and 16.0, 15.8 and 13.2 % – on those fertilized with N120Р120К120. Similar parameters of soil fertility indicators are formed by the organo-mineral fertilizer system with systematic long-term application of half the norms of organic and mineral fertilizers of manure 20 t/ha together with N60P60K60. However, the mineral system (N120P120K120) significantly less increases the humus content and content of macronutrients available for plant nutrition and does not enrich the soil with trace elements, acidifies the reaction of the soil environment

<p>Low soil fertility, pests and diseases are major problems of growth and establishment of cacao seedlings on the field. Cocoa production increases by new plantings and rehabilitation of moribund farms, but a build-up of plant-parasitic nematodes (PPN) causing dieback and declining soil fertility has discouraged many farmers, leading to a reduction in crop productivity.  In this study, the potentials of some organic wastes as fertilizers and their effects on establishment of cacao seedlings in PPN infected soils was investigated at Ibadan and Owena of Southwestern Nigeria. Goat dung (GD), organic fertilizer (OF), organo-mineral fertilizers (OMF) and NPK 15:15:15 were applied at 200, 400 and 600 kg ha<sup>-1</sup>, respectively, to cacao seedlings one month after transplanting, while unfertilized served as control. Results from the experiments showed a significant increase in percentage survival of cacao seedlings under organic fertilizers at Ibadan and Owena compared to NPK and control even at the lowest rate of 200 kg ha<sup>-1</sup> 3 years after transplanting. The incorporation of GD, OF and OMF significantly reduced the population densities of PPN compared to control. Therefore, GD, OF and OMF at 200 kg ha<sup>-1</sup> are recommended for soil application to enhance the field establishment of cacao seedlings in the soil infected with PPN.</p>

The Impact

The low level of farms income from agricultural sector mainly happens in dry season had to inappropriate soil cultivation. The utilization of soil for brick ste manufacturing is one of this case. The excavation process occurs on top soil inflicting degradation of soil fertility. Soil in the impact of this condition has a problem in providing chemical element for the agriculture, especially the lack of N. One of alternative attempts to increase the soil fertility in providing N on formerly brick ste excavation-soil is by supplying Petroganik fertilizer and compost. Petroganik and compost is an organic fertilizer containing N, P, K, the other nutrient, similar to the other organic fertilizers. The aims of the research are to determine the effect Petroganik fertilizer and compost application on N uptake and toward the growth of corn on former brick ste excavation-soil, and to know the chosen dosage which is resulting in growth and N uptake of corn. Research used is Random Block Design with 9 treatment and 3 replication. Dosage of treatment T0 : Control, Petroganik (14, 17, 20, 23) t/ha and compost (14, 17, 20, 23) t/ha. Indicator plant was used Hybrid Corn BISI 2. The result of experiment showed that : 1. Significant effect in increasing uptake of N the corn. The treatment of Petroganik 17 t/ha (P2) increasing 145 % and compost 14 t/ha (P2) increasing 93.8 %, 2. Insignificant effect on plant growth (height, number of leaf) However, it gives significant effect on dry weight of the corn biomass. The treatment Petroganik 17 t/ha (P2), increases 101.45 %, 3. The application of Petroganik fertilizer is more effective in increasing the growth and N uptake of corn than that of compost since the application of 17 t/ha of Petroganik has already increased the N uptake and growth of corn .

В условиях Республики Коми в полевом стационарном опыте на дерново-подзолистой легкосуглинистой почве изучена эффективность различных доз органических и минеральных удобрений, а также совместного их применения. Исследования проводили в 1978–2019 годах на опытных полях Института агробиотехнологий ФИЦ Коми НЦ УрО РАН. Целью проводимых исследований было изучение влияния комплексного применения удобрений на продуктивность и качество кормовых культур в шестипольном севообороте. Кормовой севооборот имел следующее чередование культур: картофель, викоовсяная смесь с подсевом многолетних трав, многолетние травы 1 г.п., многолетние травы 2 г.п., викоовсяная смесь, картофель. В результате научных исследований (более 40 лет) установлено, что наиболее эффективной была органоминеральная система удобрений, особенно при внесении 80 т/га торфонавозного компоста (ТНК) и минеральных удобрений. Многолетние исследования показали, что наиболее значительные урожаи кормовых культур (в среднем за три ротации) получены при использовании 80 т/га ТНК и NPK: однолетних трав — 4,4 т/га; многолетних трав — 6,2 и картофеля — 7,1 т/га сухого вещества высокого качества. Содержание сухого вещества в клубнях картофеля в вариантах с NPK составило 18,0–18,8%, на органическом фоне — 18,4–18,9 и при комплексном применении удобрений — 17,1–17,7; в контроле — 19,6%. Количество крахмала в картофеле незначительно различалось по вариантам опыта и равнялось 12,6–13,1%. Содержание нитратов не превышало ПДК (250 мг/кг сырой массы). Количество сухого вещества в однолетних и многолетних травах изменялось незначительно и составляло 19,0–19,8 и 25,0–26,8% соответственно. Установлено, что удобрения способствовали повышению содержания сырого протеина в однолетних и многолетних травах до 13,1–15,0% (в контроле — 11,2%) и 8,8–10,6 % (в контроле — 8,1%) соответственно. The impact of various rates of organic and mineral fertilizers was analyzed in the Komi Republic on sod-podzolic soil with low loam content. The research took place at the Institute of Agricultural Biotechnology in 1978–2019. The goal was to test forage crop productivity and quality under fertilization and six-field crop rotation. Crop rotation happened as follows: potatoes, vetch-oat mixture overseeded by perennial grasses, first-year perennial grasses, second-year perennial grasses, vetch-oat mixture, potatoes. For 40 years the combination of mineral and organic fertilizers was the most effective. The highest yields for three rotations were observed under the application of 80 t ha-1 of peat-manure compost and NPK: annual grasses produced 4.4 t ha-1; perennial grasses — 6.2, and potatoes — 7.1 t ha-1 of high-quality dry matter (DM). Potato tubers accumulated 18.0–18.8% of DM under NPK application, 18.4–18.9 — under organic nutrition, 17.1–17.7 — when using complex fertilization, and 19.6% — in the control. Starch content varied within 12.6–13.1% in potatoes. Nitrate content did not exceed the maximum acceptable concentration (250 mg/kg of raw mass). DM concentrations amounted to 19.0–19.8 and 25.0–26.8% in annual and perennial grasses, respectively. Fertilization increased crude protein amount in annual and perennial grasses up to 13.1–15.0% (versus 11.2% in the control) and 8.8–10.6 % (versus 8.1%), respectively.

The article presents an analysis of the determination of the effectiveness of mineral and organic fertilizers on the yield of winter wheat grain. The studies were carried out in 2017–2020 in the Rostov region on the southern chernozem. The object of research was the Doneko winter wheat variety. The predecessor is corn for grain. Ammonium nitrate, ANP fertilizer (16-16-16) and urea were used as mineral fertilizers, which were applied in the fertilization system of winter wheat and acted as a background option in the experimental scheme. ANP fertilizer (16-16-16) was introduced when sowing winter wheat, ammonium nitrate - scattered over thawed-frozen soil and carbamide in the heading phase by foliar method. Organomineral fertilizers were represented by the following types: Ruther, Leili 2000, Siamino Pro, Gumiful Pro, Soft Guard and Double Wine MKR (monocaliphosphate) produced by Biokepharm (Switzerland). The raw material for the production of organomineral fertilizers was the algae of the warm seas Laminaria. In the field experiment, the options for the joint application of foliar application and pre-sowing seed treatment with organomineral fertilizers were also studied. The control was the option without mineral fertilizers and the option with the background of the use of mineral fertilizers (farm fertilization system). It was found out that the use of organic fertilizers Ruter (0.5 or 0.25 l / t) and Leyli (0.25 l / t) for seed treatment before sowing, the use of Soft Guard (0.2 l / ha) and Gumiful Pro ( 0.2 l / ha) in the spring tillering phase and in the flag leaf phase against the background of sowing nitroammophoska at a dose of N32P32K32, random fertilizing on thawed-frozen soil with ammonium nitrate at a dose of N40 and the use of carbamide in the heading phase at a dose of N20 increased grain yield on average for 2018–2020 compared with the control (fertilization system of the farm) by 0.73 t / ha, or 23.0%. The maximum yield increase from the root-forming agent Ruther, used for pre-sowing seed treatment, reached 0.36 t / g, or 11.3%.

<p>The influence of long-term use of mineral and organic fertilizers, crop rotations, plant residues, soil treatment systems on humus content of common chernozems and stabilization of productivity of field crops in the arid conditions of the Middle Volga region is considered on the example of researches in the Samara area. The zone climate of field experiments is characterized as extremely continental. The sum of the active temperatures (above 10°C) is 2,800-3,000°C. The average annual rainfall is 454.1 mm with fluctuations over the years from 187.5 mm to 704.6 mm. At some years, precipitation does not happen within a month or more. Hydrothermal index in May-August is 0,7, the duration of the frost-free period is 149 days. If the humus content in the region is 4.35-4.52%, then, it is necessary to introduce 6.7-8.0 t/ha of manure per year to maintain the balance of the deficit. The introduction of biological methods for the conservation and reproduction of soil fertility (green fertilizers, perennial grasses, straw as fertilizer) reduces the loss of humus by 0.15-0.24 t/ha. This makes it possible to increase the payback of mineral fertilizers, which must be taken into account when developing fertility reproduction systems for soils. In the variants with minimal and differentiated cultivation of the soil during crop rotation in 30 years of the study, the loss of humus in the 0-30 cm layer decreased by 0.04 - 0.73% (43-789 kg per year with maximum values in the combination of direct seeding of spring crops with deep loosening for a number of crop rotations is 4.14%, significantly exceeding the control (by 0.54%). The decrease in soil fertility in the variants with constant plowing and minimal tillage contributed to an increase in the conjugation of productivity of crops with humus. Based on the research, in order to preserve the fertility of the soil of ordinary chernozem, it is necessary to use green fertilizer, leguminous perennial grasses. In the regional rotations of crop production, new generation technologies are recommended, the basis of which is differentiated tillage with the use of crushed straw as fertilizer.</p>

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.
