“…In 2021, silage maize occupied only 214 thousand hectares, although it is effectively used as a substrate for a biogas plant (Statistical Yearbook, 2021). M. Doyeni et al (2021) point out that in European countries, growing silage maize for biogas plants is a widespread practice and has proven to be effective. Ukraine, which has significant agricultural resources, also has the potential to successfully develop a biogas sector.…”

Given the growing area of maize cultivation in Ukraine and globally, research into the possibilities of using silage as a component of biogas plants to produce biogas as an alternative fuel and digestate as a bio-organic fertiliser is of high relevance and production necessity. The purpose of this study was to investigate the chemical composition of green mass of maize and its changes depending on the growing season for its use in biogas production. Field, laboratory, laboratory-field, and statistical research methods were used in the study. The findings of this study showed that the quality of maize silage depends on soil and climatic conditions, elements of growing technology, genetic characteristics of a particular hybrid, its maturity group, harvesting time, etc. The genetic characteristics of the hybrid had the greatest influence on the dry matter content, specifically, the mid-early hybrid Amaros stood out in terms of dry matter content on 10-14 August 2020 (26.61%). The highest crude fibre content was observed in the hybrid P9170 – 6.32% and 26.86%, respectively, in natural and absolutely dry matter. This hybrid belongs to the mid-season ripeness group. The shift in the harvesting time of the green mass of the maize hybrids under study also affected the characteristics of the chemical composition and the carbohydrate-lignin complex of the green mass of the maize hybrids under study. The yield of green mass of maize hybrids substantially depended on the maturity group of maize hybrids and was highest in the mid-season maize hybrids Burito – 78.1 t/ha and P9170 – 73.1 t/ha, while in the group of mid-early hybrids it was 55.3 t/ha and 68.9 t/ha in Amaros and P9071. Hybrids with a long growing season have higher green mass yields and dry matter yields per unit area. The findings can be used by farms that grow silage maize and have the opportunity to use the vegetative mass as a component of biogas plants for biogas production and digestate production

“…The samples were taken from each plot at intervals of approximately 1 month to cover the period of cover crops establishment for 2022, and each treatment had three replicates. The collected gas samples were analyzed using the gas chromatography technique with slight modifications [26,27]. By using the base area of the static chamber, within-chamber air temperature (T), air pressure (P), the constant R (0.0821 L•atm/mol•K), and chamber volume (V), the flux calculations of CO 2 , N 2 O and CH 4 were calculated according to the subsequent ideal gas law [27,28].…”

Soil treatments have a significant influence on the agricultural and environmental productivity of agricultural practices. Arable lands are one of the sources of greenhouse gas emissions (GHG) that are influenced by the chemical and physical properties of the soil and are an essential contributor to climate change. We aim to evaluate the long-term management of agricultural practices, such as different tillage systems, cover crops, and glyphosate, on GHG emissions and soil physical properties. The field trial involved three tillage systems (conventional tillage (CT), reduced tillage (RT), and no-tillage (NT)), along with variations in cover cropping (with and without cover crops) and glyphosate application (with and without glyphosate). These treatments were implemented during the cultivation of oilseed rape in 2022 as part of a cropping sequence consisting of five crops: winter wheat; winter oilseed rape; spring wheat; spring barley; and field pea. Greenhouse gas emissions (carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O)) were directly measured using a closed static chamber system. Through the examination of these management techniques, the soil’s physical properties over the studied period were assessed for their impact on GHG fluxes. The findings of the study reveal that N2O emissions were relatively low during the first month of measurement, with significant differences (p < 0.05) observed in the interaction between cover crop and glyphosate treatments. Additionally, N2O emissions were notably elevated in the reduced (0.079 µg m−2 h−1) and conventional tillage (0.097 µg m−2 h−1) treatments at the second month of measurement. Regarding CH4, increased emissions were observed in the reduced tillage and cover crop treatments. CO2 emissions exhibited variability across all of the investigated treatments. Notably, GHG fluxes spiked at the second measurement, signifying the maximum uptake of nutrients by the main plants during the growth phase. Greenhouse gas emissions leveled off across all of the treatments following the harvest, marking the end of the cultivation period. The influence of the deployed techniques varied across the determined physical parameters of the soil. The incorporation of cover crops contributed to improved water content and, further, to electrical conductivity. Glyphosate use showed no direct impact on physical properties of the soil while the different tillage treatments had varying effects on the distribution of the physical properties of the soil with respect to the degree of disturbance or tillage-induced changes. Additionally, GHG emissions were strongly correlated with precipitation at one week and two weeks before sampling, except for CO2, which showed a weaker correlation at two weeks before GHG sampling. The findings indicate that reduced and conventional tillage methods might adversely affect greenhouse gas emissions and plant functionality, particularly concerning nutrient release and uptake, especially in temperate climate conditions.

“…To cope with these challenges, organic farming and adaptive and environmentally friendly technologies are being implemented. The use of digestates for soil fertilization is an important issue regarding this problem (Odlare et al 2011;Abubaker et al 2015;Doyeni et al 2021b;Nkoa 2014;Іrandoust 2016;Arthurson 2009;Gell et al 2011).…”

This paper presents calculations of the economic indicators of the researched elements of the cultivation technology of corn for grain and vegetable crops in Ukraine, which indicate that the cultivation of these crops is cost-effective in all variants of the experiment. The research has established that the increase in the economic efficiency of the production of these crops when applying different rates of fertilizers is achieved due to a more significant positive effect of the increase in productivity compared to additional costs associated with the use of these farming practices, while additional costs caused by the use of fertilizers are paid off many times over. It has been proven that the use of mineral fertilizers and their combination with high rates of bio-organic fertilizer (digestate) when growing agricultural crops helps to increase productivity. There have been further developed theoretical and practical provisions regarding the ecological problem of livestock waste disposal, 162 in particular those of pig farms, and agricultural farms, i.e. the provision of organic fertilizers to ensure the yield increase as well as improvement in the quality of agricultural and vegetable crops, so as to make it possible to obtain high-quality products of plant and vegetable production during livestock waste disposal. The proposed approach to the economic assessment of technologies for growing corn for grain and red beet depending on the fertilization system makes it possible to increase the level of productivity of agricultural and vegetable crops with the effective use of bio-organic fertilizers in the modern conditions of sharp increases in the costs of mineral fertilizers.
