Aim. To substantiate the agroecological estimation of the performance of a short crop rotation in conditions of intense and organic system of fertilization on the basis of restoring normative parameters of emission and se- questration of С-СО 2 circulation while using by-products as organic fertilizers in conditions of modern climatic system of the Forest-Steppe of Ukraine. Methods. Field, statistical, laboratory. Results of Investigations. The performance of short crop rotations is determined by the capacity of С-СО 2 balance. Strong inverse correla- tion was found between the capacity of N and the ratio between C and N in the agrocenosis, which demon- strated that enhancing the humifi cation processes (ratio constriction) led to the increase in the capacity of С org balance and the decrease in the capacity level of С-СО 2 balance (enhancing mineralization), related to the reduction in the performance of crops in the agrocenosis of a crop rotation compared to the organic system of fertilization. The capacity of С-СО 2 and С org balance correlates at the medium level of inverse direction, and the yield of the main products, feed units and digestible protein correlates at the level of strong direct correlation. Conclusions. General mineralization of by-products and humus in the agrocenosis and humifi cation processes are antagonists, so extending the ratio between С and N at the intense fertilization system stimulates the in- crease in performance and reducing С to N similar to the organic fertilization system enhances the humifi cation process due to binding of С org into humus and limits mineralization which leads to the reduction in agrocenosis performance at the organic fertilization system.

Aim. To conduct complex agrophysical, physical-chemical substantiation of the effi ciency of the organic fer- tilization system in terms of nitrogen balance and organic carbon in the agroecosystem of a fi ve-fi eld grain- growing and weeding crop rotation fi lled with cereals and legumes up to 40 % and the use of by-products for fertility restoration and improvement of the agrogenesis of regraded chernozem in the central part of the Forest-Steppe of Ukraine. Methods. Laboratory-analytical, experimental fi eld, computational, statistical. Results. The systematic application of the organic system of fertilization in a short grain-growing and weeding crop rotation with the use of by-products as organic fertilizers promotes the increase in the points of exchange neutrality and the decrease in the unsaturation of regraded chernozem with the alkali of the tilled layer, while the increase in microaggregation and structure-building is conditioned by the approximation of potential acid- ity to the isoelectric state of soil colloids which is a feature of the process of biologization and simulation of natural soil formation in agroecosystems of the central part of the Forest-Steppe of Ukraine. Under the organic fertilization system the decrease in the agroecosystem performance is related to the decrease in the volume of nitrogen balance which testifi es to the decrease in the intensity of its circulation in agroecosystem: the processes of enhancing the humifi cation of by-products and the formation of prohumus substances prevail, ac- companied with the intensifi cation of atmospheric CO 2 involvement in the formation of the total phytomass of the harvest, and the agroecosystem transforms into a stock system, which may be characterized as a basic sys- tem for organic production of plant cultivation. Conclusions. The elaborated system of organic fertilization of crops in a fi ve-fi eld grain-growing and weeding crop rotation allows avoiding the use of organic fertilizers and perennial grasses and using by-products of plant cultivation instead to saturate the crop rotation with legumes up to 30–40 %, the application of nitrogen-fi xing and phosphate-mobilizing preparations allows ensuring the production of organically pure products with simultaneous restoration of both fertility and the natural model of the chernozem agrogenesis of the central part of the Forest-Steppe of Ukraine.

Aim. To compare nitrogen-carbon circulation in organic and intense fertilization system in agrocenosis of a short crop rotation with grain and intertilled crops on podzolic highly-regraded low-humus chernozem in the Central Forest-Steppe of Ukraine. Methods. Summarization of the study results in the permanent fi eld experiment, statistical method, dispersion method, correlation analysis of performance parameters, structures of phytomass, quality and quantity items of carbon and nitrogen balance. Results. In the organic system of fertilization, the removal of N increased to 0.25 units per capacity unit of nitrogen balance, which is 1.47 times higher, and the total loss of N increased 1.1 times (0.31 units per capacity unit of nitrogen balance) regarding the intense system of fertilization, but with lower values of balance items for nitrogen in the agrocenosis. Direct and strong correlation relationships were revealed between the yield of fodder units and the content of organic carbon in the structural components of the total phytomass: with organic carbon in the main products and root mass – R = 0.86–0.88 ± 0.02; R^2 = 0.74–0.77, and with the content of organic carbon in by-products and non- commodity total phytomass the relation to the yield of fodder units was on the level of direct mean correlation: R = 0.58–0.65 ± 0.02; R^2 = 0.34–0.43. The increase in the yield of fodder units is accompanied with the 1.32- fold decrease in the nitrogen balance capacity regarding the intense system of fertilization. Conclusions. It was established that in case of organic system of fertilization the ratio of organic carbon and N in the agrocenosis of a short crop rotation is the most optimal and approximates 30:1, which is the most profi table for humifi cation of by-products and decrease in the intensity of humus mineralization. Balance capacity is a restrictive factor in the circulation of organic carbon and N at the organic fertilization system, as it may considerably concede the balance capacity of organic carbon and N at the intense fertilization system, which had a negative impact on the performance of crop rotation.

Aim. To establish the effect of different fertilization systems in short fi eld crop rotation on the change in the state of humus in the dark gray podzolic soils in Western Forest-Steppe of Ukraine. Methods. Field studies were carried out in a stationary experiment of the Department of Soil Science and Agricultural Chemistry of the L’viv National Agrarian University; determination of humus content – according to DSTU 4289:2004, and that of its labile forms – in accordance with DSTU 4732:2007, fraction-group composition – by Ponomare- va-Plotnikova’s method, according to the measurement procedure 31-497058-008-2002. Results. The use of organo-mineral fertilizer system in short fi eld crop rotation with the saturation of organic fertilizers of 15 t/ha of crop rotation contributes to the humus content increase by 0.7 % after the third rotation in 0–40 cm layer of dark gray podzolic soil, the increase in the share of stable forms of humic compounds up to 57–59 % and the increase in the ratio of R HA :R FA to 1.3–1.4. The study demonstrated very high dependence of amount of gross energy reserves in the humus on the R HA :R FA ratio. Conclusions. The combined application of organic fertili- zers in the form of manure, non-market of the crop (straw) and siderate, along with mineral fertilizers is re- commended in short fi eld crop rotations of Western Forest-Steppe of Ukraine toensure expanded reproduction of fertility of dark gray podzolic soil, improvement of its humus status, increase in gross energy reserves and the share of the stable forms and humic acids in the humus.

В статье представлены результаты изучения экономической и энергетической эффективности возделывания многолетних трав сенокосного и пастбищного использования. С 2007 по 2012 год проведено изучение продуктивности и экономической эффективности возделывания многолетних трав сенокосного использования в лесостепной зоне, коренное улучшение естественных кормовых угодий с 2011 по 2016 год — в южной лесостепи Западной Сибири. Продуктивность и рентабельность производства многолетних трав сенокосного использования с применением минеральных удобрений в лесостепной зоне наиболее высокими были у люцерны и составили 3,2 т/га корм. ед. и 190% соответственно при затратах 8,8 тыс. руб./га. Выход энергии — 43 ГДж/га, энергетический коэффициент (отношение величины выхода продукции к затраченной энергии) — 8,1. Коренное улучшение лугов с применением минеральных удобрений обеспечило получение 0,8 т/га корм. ед. при затратах 4,1 тыс. руб./га, рентабельность составила 56%. Продуктивность естественных угодий при коренном улучшении с использованием органических удобрений — 0,9 т/га корм. ед., рентабельность — 278% при затратах 1,9 тыс. руб./га. Выход энергии с использованием минеральных удобрений — 9,1 ГДж/га, энергетический коэффициент — 1,9, на фоне органических удобрений — соответственно 10,2 ГДж/га и 3,4. Внесение органических удобрений один раз в 5 лет способствовало существенному снижению затрат при коренном улучшении лугов и значительному повышению рентабельности производства. На основании полученных результатов можно заключить: рентабельность производства многолетних трав достаточно высокая, особенно при использовании органических удобрений. Поэтому в хозяйствах с экстенсивными технологиями многолетние травы должны составлять основу кормопроизводства. This article reports on economic and energy efficiencies of perennial grasses cultivated in pastures and haylands. Experiments on hay production took place in the forest-steppe in 2007–2012. Optimization of natural forage lands was conducted in 2011–2016. Alfalfa had the highest hay productivity and economic efficiency under mineral nutrition yielding 3.2 t ha-1 of feed units. Payback amounted to 190%, production costs — 8.8 thousand rubles ha-1. Energy yield reached 43 GJ ha-1, energy coefficient (yield-to-energy ratio) — 8.1. Mineral fertilizers led to the yield of feed units of 0.8 t ha-1, costs of 4.1 thousand rubles ha-1, and profitability of 56%. Under organic fertilization natural forage lands produced 0.9 t ha-1 of feed units, profitability reached 278% while costs — 1.9 thousand rubles ha-1. On the background of mineral nutrition energy yield amounted to 9.1 GJ ha-1, energy coefficient — 1.9, on the background of organic nutrition — 10.2 GJ ha-1 and 3.4, respectively. Organic fertilization once in 5 years significantly reduced costs and increased profitability. Production of perennial crops resulted in high payback, particularly under the application of organic fertilizers. Therefore, farms applying extensive cultivation practices should widely grow perennial grasses.

The goal of this study was to provide quantitative agronomic data and environmental performance through a life cycle assessment of camelina in a crop rotation. For this purpose, camelina [Camelina sativa (L.) Crantz] was included in a crop rotation (camelina-barley [Hordeum vulgare (L.)]-camelina) fertilized with two organic fertilizers (dewatered sludge and composted sludge) during three growing seasons (2015–2018). Three treatments were considered in this experimental study of 0.018 ha: (1) Fertilization with composted sludge (15 t ha−1), (2) fertilization with dewatered sludge (35 t ha−1), and (3) control treatment without fertilization. Results showed that camelina’s yield was affected by climatic conditions, ranging from 0.9 to 1.4 t ha−1 in the first season (2015/2016) and the third season (2017/2018 and did not present significant differences between treatments. The yield components with a positive response to organic fertilization were number of silicles, number of seeds per plant, and thousand-seed weight, with an average increase compared to the control of 23.7%, 16.5%, and 18.5%, respectively. A negative correlation was observed between organic fertilization and total fat content, contrary to the increase in protein content observed with organic fertilization. The environmental assessment of this crop rotation revealed that fertilization and transport were the main hotspots. Despite the undesirable weather limitations, this study showed a positive response of camelina’s yield components and seed quality to organic fertilization. By applying these organic fertilizers, it may be possible to obtain favorable camelina yields and promote waste valorization. To minimize the environmental impacts of this crop rotation with camelina, the main recommendations could be to reduce the distances between the dewatering and composting sites and the field and optimize fertilization rates. Further research is needed to determine the application of these organic fertilizers in the long term.

The article presents results of the research concerning impact of mineral, organic and organic-mineral system of fertilization with a different share of organic fertilizers on the fertility of dark-grey podzolic soil during the period of four cycles of a short cycle cereals-growing crop rotation. It is argued that application of organic-mineral fertilization with the share of 15.0 ton/ha of organic fertilizers secures increase of the content of total humus in the soil (+ 0.24% and + 6.24 ton/ha to the indicator of the first cycle) after the fourth cycle of a short cycle field crop rotation. Mineral system of fertilization does not supply an extended reproduction of humus share in the soil (-0.06% and -1.56 ton/ha, as compared to the similar variant of the first cycle of crop rotation). It is determined that the dynamics of the content of the main elements of mineral nutrition in the soil also depends on fertilization system. Under conditions of stationary field experiment the largest share of low-hydrolysed compounds of mineral nitrogen (139 mg/kg of soil), phosphorus (113 mg/kg of soil) and potassium (109 mg/kg of soil) in one layer (0–20 cm) was secured by organic-mineral system of fertilization with the share of organic fertilizer of 15 ton/ha at the end of the fourth cycle of crop rotation. Comparing to the first cycle, the share of the main nutrition elements in the variant increased by 27.1, 36.1 and 39.7% respectively. Such a system of fertilization supplied the highest level of the yield of agricultural crops during the four cycles of crop rotation. However, one should note that payback of yield was reduced from a cycle to cycle in case of fertilizers application. Key words: fertilization system, crop rotation, humus content, nutrition elements, yield.

Four year research (2015–2018) at Bila Tserkva National Agrarian University proved that plant residues and non-market products of the field five course grain row rotation are important sources for soil humus formation. On the unfertilized areas, fertilized withn8 t/ha of animal manure + N76P64K57, 12 t/ha of animal manure + N95P82K72 and 16 t/ha of animal manure + N112P100K86 humus percentage formed due to humification of plants matter was correspondently 51.4; 40.3; 37.7 and 36.1 %, with animal manure – 0; 15.3; 17.2 and 18.7 %, with by-products of farming – 44.0; 40.8; 41.7 and 42.1 %, with herbage of white mustard – 4.6; 3.6; 3.4 and 3.1 %. With the increase of fertilizers level this index regarding plants matter and green manure decreases, while animal manure provides for the index slight increase. On the unfertilized areas humus balance under cultivated crops as sunfl ower and corn is negative, but under other crops in rotation it is positive. On the fertilized areas under all crops this index is positive. When applying the biggest amount of fertilizers, annual gain in soil humus is 1.1 t/ha. Humus balance is negative on all the variants of research under the condition of disposal of non-market products from the fi elds of crop rotation. Along with plants matter, plant by-products and herbage of white mustard the amount of humus provided to the soil was equal to the application of correspondently 14–33, 12–36 and 1.3–2.6 t of animal manure per hectare of tilled fi eld. Under zero, the fi rst, the second and the third levels of soil fertilization, soil received correspondently 4.08; 5.98; 7.46 and 8.73 t of plants matter 68–71 % of which are root and the others are above surface. The percentage of by-products of crops in the rotation increases with fertilizers amount increase. Soy, winter wheat, sunfl ower and spring barley have a bigger gain in above surface rather than root mass due to increase of fertilizers amount. The highest productivity from one hectare of tilled fi eld in a crop rotation (5.63 t of dry matter, 7.84 t of fodder units, 0.671 t of digestible protein) is gained due to application of 16 t/ha of animal manure + N112P100K86, though the most economically viable amount is 12 t/ha animal manure + N95P82K72. Key words: humus balance, soil, fertilizers, crop, by-products, plants matter, crop rotation, grain crops, index of ecologization, productivity.
