Economic efficiency of using digestate from biogas plants in Ukraine when growing agricultural crops as a way of achieving the goals of the European Green Deal

Abstract

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.

Evaluation of Ecological Adaptability of Oilseed Radish (<i>Raphanus sativus</i> L. var. <i>oleiformis</i> Pers.) Biopotential Realization in the System of Criteria for Multi-Service Cover Crop

“…It is important to investigate the potential of using varietal green manure under variant technological and calendar-term use against the background of widespread involvement of by-products left after harvesting the main crop (Boselli et al, 2020;Kenjaev and Davronova, 2023). This approach is in line with the defined strategy of the green course and adaptive soil conservation in view of the dynamic processes of soil degradation (dehumidification, over-compaction, loss of agronomically valuable structure (Yadav et al, 2021;Lohosha et al, 2023) and the proportion of moisture-resistant aggregates (Abdulraheem and Tobe, 2022), and increased greenhouse gas emissions (Ansari et al, 2022;Israt and Parimal, 2023)).…”

An advanced European overview of the bioenergy efficiency of using digestate from biogas plants when growing agricultural crops

“…Considering a growing need for environmentally friendly agricultural production, organic fertilizers have become an object of extensive research. Composts, manures and other organic materials are used to improve soil fertility, since they contain natural nutrients and help to support biological life in the soil (Koszel and Lorencowicz 2015;Reuland et al 2021;Kovačević et al 2022;Lohosha et al 2023a).…”

Efficiency of Digestate from Biogas Plants for the Formation of Bio-Organic Technologies in Agriculture

“…Pantsyreva et al, 2023 focuse on bio-organic cultivation technology and the role of digestate while growing legumes. Lohosha, Palamarchuk, Krychkovskyi, 2023 prove that the use of a combination of mineral fertilizers with high rates of bio-organic fertilizer (digestate from biogas plants) when growing crops helps to increase productivity and is of great importance for Ukrainian agriculture. Anaerobic digestate from biogas plants is recognized worldwide for its beneficial fertilizer qualities (Lind et al, 2021).…”
