Orchid fertilization is fundamental for a satisfactory plant growth and development for commercial orchid production as well as in collections. Mineral and/or organic sources can be used for fertilization. The objective of this study was to evaluate the effect of the use of organic and/or mineral fertilizers on the nutrition and growth of orchid (Laelia purpurata 'werkhanserii' x L. lobata 'Jeni') seedlings in greenhouse. The following fertilizers were tested: an NPK fertilizer + micronutrients; a Ca source in the form of calcium nitrate; two organic fertilizers, one prepared with a mixture of bone meal, castor meal and ash, and a similar commercial fertilizer. The organic fertilizers were distributed on the surface of the pots every two months and the minerals were applied weekly to the substrate in 25 mL aliquots of a solution containing 1 g L-1 of the respective fertilizer. The plant response to the application of mineral together with organic fertilizer was better, with higher dry matter production than by the isolated application of each fertilizer (organic or mineral). The treatments with calcium nitrate + NPK fertilizer did not differ significantly from the use of NPK fertilizer, probably due to the S deficiency detected in a mineral analysis of the tissues. Commercial organic fertilizer had a very elevated B level, leading to toxicity symptoms, reduced growth and necrotized tips of the older leaves in all fertilized treatments.

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.

ABSTRACT The effects of inorganic (ammonium nitrate and triple superphosphate) and organic (fish bone-meal) fertilizers on the biodegradation rates of Venture condensate within a sand-beach environment were assessed over 333 days. Field results showed that the organic fertilizer stimulated microbial growth and metabolic activity to the greatest extent. However, based on chemical analysis of residual oil concentrations and composition, the application of inorganic fertilizers was the superior bioremediation strategy. This paradox between microbiological and chemical results was attributed to the selective growth of different bacterial populations, the preferential use of components within the organic fertilizer over oil by the indigenous microflora, and the production of toxic metabolic by-products from the degradation of the organic fertilizer.

Fertilizer Use

Granular organic fertilizers have been increasingly used in agriculture due to the longer delivery of nutrients to plants and the milder impact on the environment. The aim of this study was to determine the energy, environmental and economic efficiency of granular and non-granular organic fertilizers. Four technological scenarios of organic fertilizer use were used for comparative assessment: (1) manure fertilization (16.0 t ha−1), (2) manure fertilization (30.0 t ha−1), (3) manure pellet fertilization (2.0 t ha−1), and (4) fertilization with meat and bone meal pellets (0.7 t ha−1). Experimental studies using the mass flow method of laser spectroscopy were performed to evaluate the comparative environmental impact of granular and non-granular organic fertilizers. Economic assessment was performed for mechanized technological operations of loading, transportation and distribution of organic fertilizers, estimating the price of aggregates used and fuel consumed, the costs of individual technological operations and other indirect costs. The results showed that for mechanized technological operations, when fertilizing with granular organic manure and meat and bone meal fertilizer, energy consumption is 3.2 to 4.0 times lower compared to fertilization with manure. The average ammonia (NH3) emissions from granular organic fertilizers were found to be six times lower than from non-granular organic fertilizers. The lowest costs for mechanized works were incurred when using meat and bone meal pellets, the highest economic benefits of organic fertilizers by elements was when using manure 30 t ha−1, and the highest costs for organic fertilizers were incurred when using manure pellets.

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.

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.

Control Analysis

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.
