Purpose. To study the adaptive elements of technology for growing high-stem forage crops (corn, sugar sorghum, sudanese grass, sorghum-sudanese hybrid) and features of biomass formation for biogas production in the right-bank forest-steppe of Ukraine. Methods. Field, laboratory, quantitative-weight, visual, calculation-comparative, mathematical-statistical. Results. The researche results provided the adaptive technology elements cultivation of high-stem forage cultures for the further using of biomass for biogas production. The use of complex mineral fertilizers (NPK) on crops of high-stem forage crops led to an increase in crop productivity compared to the application of nitrogen fertilizers (N). Transferring of the crops harvesting time from the phase of stem prolongation to the phase of the heads forming, and especially the milk-wax ripeness of the grain provided an increase in yield and quality of biomass. The application of the crop nutrition system and biomass harvesting in different phases of fodder crop development ensured the yield of corn at the level of 26.8-66.5 t/ha, sudanese grass – 26.6-60.2 t/ha, sorghum-sudanese hybrid – 34,1-114.7 t/ha and sugar sorghum – 37.3-105.4 t/ha, estimated yield of biogas from 2.83 to 32.54 thousand m3/ha and energy from biogas – from 51.9-709.4 GJ/ha, depending on the fertilizer option and harvesting period. Conclusions. The application of the optimal fertilizer system (N90P90K90) and harvesting of biomass in the phase of milk-wax ripeness of grain the highest productivity was provided by crops of high-stem forage crops: yield of corn biomass at the level of 54.9-66.5 t/ha, sudanese grass – 45.0-60.2 t/ha, sorghum-sudanese hybrid – 82.0-114.7 t/ha and sugar sorghum 74.3-105.4 t/ha, estimated biogas yield from 12.91 to 32.54 thousand m3/ha and energy from biogas – 281.4-709.4 GJ/ha, with a level of profitability from 7.1 to 177.6% dependently on the crop and nutrient background.

Carbon Footprints

The aim of this paper is to analyse to what extent the existing eco-innovations in the German fertilizer domain might reduce the fertilizer carbon footprint without compromising on crop productivity. The continuously growing demand for agricultural products will require a further increase in agricultural production mostly achieved with additional external inputs (fossil energy, pesticides, irrigation water and fertilizers). Fertilizer in general and nitrogen fertilizers in particular are major factors for yield increases in crop production. On the other hand, emissions of greenhouse gases play a dominant role in the debate on the environmental burden of fertilizers. Typical mineral fertilizers were compared with so-called stabilized nitrogen fertilizers and secondary raw material fertilizers in this study. Additionally, an effect of the combination of irrigation with fertilization (i.e. fertigation) was investigated. With an adopted life cycle assessment approach focusing on CO<sub>2</sub> and N<sub>2</sub>O emission, the carbon footprints of the different fertilizer options were considered. The calculations showed that especially the use of stabilized nitrogen fertilizer reduced the fertilization-related carbon footprint up to 13%. However, because of higher costs or incomplete supply chain relationships, adoption of these innovations is expected to be rather limited in the near future. Fertilizers made from secondary raw materials resulted in similar carbon footprints as mineral ones, but they can help to close nutrient cycles and use by-products of other production processes.

Different Doses

The productivity of agricultural crops is the most variable and integral indicator of their vital activity, which accumulates their genetic potential, soil fertility, weather conditions and components of agricultural technology. Soybean under optimal growing conditions (the reaction of the soil is close to neutral, sufficient phosphorus and potassium nutrition, the use of nitraginization) assimilates from the air about 70 % of the total nitrogen requirement. Therefore, it is believed that it is enough to apply only a starting dose of nitrogen fertilizers (20–40 kg/ha a. s.), to get a high yield with good indicators of grain quality. The results of studies of the influence of long-term (8 years) application of different doses and ratios of fertilizers in field crop rotation on podzolized chernozem in the conditions of the Right -Bank Forest-Steppe of Ukraine on the yield and quality of soybean seeds preceded by spring barley were presented. It was found that crop yields could be increased by 18–77 % owing to different doses, ratios and types of fertilizers. The highest indicators of seed yields for three years of the research (3,02 t/ha) were obtained under the application of mineral fertilizers at a dose of N110P60K80 per 1 ha of crop rotation area, including under soybean – N60P60K60. Exclusion of the nitrogen component from the complete fertilizer (N60P60K60) reduced its yield by 26 %, phosphorus – by 17, and potassium by 11 %. There was no significant decrease in soybean yield in the variant of the experiment with a decrease in the proportion of potassium in the composition of complete mineral fertilizer (N60P60K30) for three years of study. The largest mass of 1000 soybean seeds was formed at doses of N60К60 fertilizers, and their protein content — under the application of complete mineral fertilizer in doses of N60P60K60 and N60P60K30.

Digestate from biogas production can be recycled to the soil as conditioner/fertilizer improving the environmental sustainability of the energy supply chain. In a three-year maize-triticale rotation, we investigated the short-term effects of digestate on soil physical, chemical, and microbiological properties and evaluated its effectiveness in complementing the mineral fertilizers. Digestate soil treatments consisted of combined applications of the whole digestate and its mechanically separated solid fraction. Digestate increased soil total organic C, total N and K contents. Soil bulk density was not affected by treatments, while aggregate stability showed a transient improvement due to digestate treatments. A decrement of the transmission pores proportion and an increment of fissures was observed in digestate treated soils. Soil microbial community was only transiently affected by digestate treatments and no soil contamination from Clostridiaceae-related bacteria were observed. Digestate can significantly impair seed germination when applied at low dilution ratios. Crop yield under digestate treatment was similar to ordinary mineral-based fertilization. Overall, our experiment proved that the agronomic recycling of digestate from biogas production maintained a fair crop yield and soil quality. Digestate was confirmed as a valid resource for sustainable management of soil fertility under energy-crop farming, by combining a good attitude as a fertilizer with the ability to compensate for soil organic C loss.

Представлена комплексная оценка эффективности диверсификации севооборотов, а также способов обработки почвы и влияния азотных удобрений при возделывании сои в условиях засушливого климата центральной лесостепной зоны Зауралья. По результатам исследований, проведённых в 2010–2020 годах в Курганском НИИСХ – филиале УрФАНИЦ УрО РАН, установлено влияние гидротермических условий региона и агротехнических приёмов на формирование урожайности сои. В острозасушливые годы с гидротермическим коэффициентом 0,3–0,6 урожайность сои снижалась наполовину по сравнению с благоприятными по тепло- и влагообеспеченности периодами (ГТК — 1,1–1,2). На фоне удобрений и надёжной системы защиты посевов сои от сорных растений менее затратная поверхностная обработка по урожайности не уступала вспашке. Минеральный азот в дозе N30 на фоне средней обеспеченности почвы подвижным фосфором в острозасушливые годы обеспечил прибавку зерна сои 0,28 т/га, в благоприятные по условиям увлажнения годы прибавка от применения N30 увеличилась до 0,43 т/га. Диверсификация традиционного четырёхпольного зернопарового севооборота путём замены пшеничного поля посевами сои обеспечила повышение продуктивности, улучшение качества продукции и экономических показателей. Рентабельность производства продукции с севооборотной площади в вариантах с ресурсосберегающей поверхностной обработкой выросла до 110% без удобрений и до 117% — на фоне N30 против 49 и 66% в зернопаровом севообороте. В результате многолетних исследований в контрастных погодных условиях установлено, что производство сои в полевом севообороте в центральной лесостепной зоне Зауралья рентабельно даже в острозасушливые годы. При низком уровне урожайности (0,50–0,70 т/га) рентабельность составляет 30–50%. В благоприятные годы ресурсы зауральского климата позволяют получать урожайность сои на уровне 1,40–1,80 т/га. При этом рентабельность повышается до 220%. The report deals with the optimization of a rotation system as well as the effect of tillage and nitrogen fertilizers on soybean productivity under the drought of the central forest-steppe in Trans-Urals. The investigation was conducted at the Kurgan Research Institute of Agriculture in 2010–2020. The aim was to test the effect of tillage, moisture and temperature on soybean yield. Drought (hydrothermal coefficient of 0.3–0.6) reduced soybean productivity by 50% in comparison to favorable conditions (hydrothermal coefficient of 1.1–1.2). Less expensive surface tillage was as effective as plowing under fertilization and weed control. In dry years application of N30 increased grain yield by 0.28 t ha-1 under medium content of soluble P. Under favorable conditions the increase amounted to 0.43 t ha-1. Substitution of wheat with soybean in the conventional four-field crop rotation system resulted in higher crop productivity, yield quality and economic effectiveness. Payback raised up to 110% under surface tillage and no fertilization and 117% — on the background of N30 versus 49 and 66% obtained under fallow and grain crop rotation. Soybean production was cost-effective even under drought. Low soybean yield (0.50–0.70 t ha-1) resulted in profitability of 30–50%. Favorable conditions of the region provided soybean yield of 1.40–1.80 t ha-1, increasing profitability up to 220%.

Results of studying effect of mineral fertilizers in combination with inoculation with nitrogen-fixingbacteria on chickpea productivity in podzolic black soil of Right-Bank Forest-Steppe of Ukraine havebeen shown. Pre-sowing bacterization contributed to the active formation and functioning of thesymbiosis, provided that the background of nitrogen fertilizers did not exceed 60 kg/ha. Under theinfluence of mineral fertilizers both separately and in combination with seed inoculation, chickpea yieldincreased by 10.8–15.2 hwt/ha compared to the variant without fertilizers and without inoculation.It was established that in order to obtain high and stable yields of chickpea seed in podzolic blacksoil of Right-Bank Forest-Steppe of Ukraine with low content of nitrogen of alkalihydrolyzing compoundsand high content of mobile phosphorus and potassium, its fertilization system should include applicationof phosphate and potash fertilizers in the dose of 60 kg/ha during primary tillage, and nitrogen fertilizers– for presowing cultivation. Before sowing, seeds should be processed with the suspension of ammoniummolybdate and Ryzobofit.

The article presents the results of field research conducted in 2018-2019 on leached Chernozem of the Volga forest-steppe. The objects of research are varieties of spring wheat-Tulaykovskaya 10, Yoldyz and Tulaykovskaya 108. At different seeding rates of 5.0 and 5.5 million germinating seeds per ha, the effect of mineral fertilizers on 1 ha was studied. They were represented by a complete mineral fertilizer (azofoska) and fertilizing with a mineral nitrogen fertilizer in the tillering phase at doses of 30, 60 and 90 kg of AD/ha against this background. Analysis of the yield of spring wheat varieties indicates that the harvest of grain variety Yoldyz in variants with a seeding rate of 5.5 million germinating seeds per ha against the background of the application of ammonium nitrate at a dose of 60 kg of DA (2.52 t/ha) was superior to other varieties Tulaykovskaya 10 and Tulaykovskaya 108 (2.51 and 2.46 t/ha). The maximum increase in seed productivity when adding ammonium nitrate in the tillage phase of the crop was in Tulaykovskaya 10 variety (0.34 t/ha), the lowest in the Yoldyz variety (0.06 t/ha) compared to the variant with amofoska application in the pre-sowing cultivation. When increasing the doses of nitrogen fertilizers there was an increase in the water content of all the studied varieties by 1-3 PCs. While increasing the seeding rate from 5.0 to 5.5 million germinating seeds per 1 ha the number of grains in the ear changed on average for varieties by 1-2 PCs. Of all the studied varieties, the largest mass of 1,000 grains was in the Yoldyz variety (40.56 g) after azofoska application in the presowing cultivation + N60 during tillering at a seeding rate of 5.0 million germinating seeds per 1 ha, the smallest in the Tulaykovskaya 108 variety (37.87 g) after azofoska application at a dose of 0.15 t/ha at a seeding rate of 5.0 million   germinating seeds per 1 ha.

A new direction in the use of lactic acid bacteria inoculants is their application for renewable raw materials ensiling for biogas production. The aim of the study was to demonstrate the possibility of stimulating the synthesis of propionic acid in the process of co-fermentation of selected strains of Lactobacillus buchneri and L. diolivorans as well as L. buchneri and Pediococcus acidilactici. L. buchneri KKP 2047p and P. acidilactici KKP 2065p were characterized by the special capabilities for both synthesis and metabolism of 1,2-propanediol. L. diolivorans KKP 2057p stands out for the ability to metabolize 1,2-propanediol to propionic acid. As a result of the co-fermentation a concentration of propionic acid was obtained at least 1.5 times higher in the final stage of culture in comparison to cultivating individual species of bacteria separately. The results of in vitro experiments were applied in agricultural practice, by application of two lactic acid bacteria inoculants in ensiling of grass silage and improving its suitability for biogas production. Grass silages made with the addition of the inoculant were characterized by the content of 1,2-propanediol, 1-propanol and propionic acid ensured extension of the aerobic stability from 4 to 7 days in comparison to untreated silages. It was found that the use of both inoculants resulted in an approximately 10 - 30% increase in biogas yield from this raw material.

A powerful factor in increasing the yield of feed mixtures is the use of mineral fertilizers. On average, over 4 years of research, the yield of green mass increases from 13.8 tons per hectare at the control (without fertilizers) to 27.4 tons per hectare (almost 2 times). However, the effectiveness of the use of mineral fertilizers depends on how the sunflower and annual herbs are placed in space. Thus, on all backgrounds of mineral nutrition, the highest yield of green mass was obtained by sowing sunflower and annual herbs in separate strips with strip widths of 180 cm: N85P38K46 - 28.2 tons per hectare; N99P44K54 - 32.9 tons per hectare; N113P51K61 - 34.2 tons per hectare. In the same conditions, both narrowing the bands to 90 cm and expanding to 360 cm reduce the yield of the object of study. Mineral fertilizers also have a great influence on the gross yield of raw fat (an increase of 2.8 times), feed units - from 2,562 to 3,904, crude protein - 1.9 times, exchange energy - 2.4 times. As a result, the payback of each ruble of the cost of mineral fertilizers provides for the production of 1.5 rubles, and the bioenergy coefficient increases to 4.4, versus 2.2 for mixed sowing of sunflower and annual herbs.

The article presents the results reached in our study of the influence of mineral fertilizers and growth regulators on symbiotic capacity of field pea in the conditions of Western Forest-Steppe. Experimental part was carried out during 2016-2018 on the field of the TPC Podilya at the SAEUP, the typical black soil, characterized as deep, low-humus, and heavy gravel on forest-like loams. The results indicate that the productivity of field pea largely depended on the effective interaction of the host plant and nodule bacteria. Application of phosphorus-potassium fertilizers and small doses of nitrogen fertilizers improved the biological fixation of nitrogen. Spray application of growth regulators at the budding-flowering phase continued the functioning of the red pigment of synthesized leghemoglobin in the nodules. The positive effect of mineral fertilizers and growth regulators on the symbiotic potentials of field pea plants was confirmed. The total symbiotic potential characterizes the state of legume-rhizobium symbiosis. The duration of active functioning of nodules on pea roots and their ability to fix biological nitrogen during the growing season define the magnitude of the active symbiotic potential. During the growing season, the total symbiotic potential indicators were the highest for the Chekbek variety and amounted to 13.1 thousand kg*days/ha (after application of N30P30K45 with the Vympel growth regulator). After application of the same combination of mineral fertilizer and growth regulator, the Gotovsky variety demonstrated - 10.6 thousand kg*days/ha, the Fargus variety – 10.0 thousand kg*days/ha.
