Abstract

The paper highlights calculations of bioenergy indicators when growing corn for grain and vegetable crops in Ukraine. The research results indicate the economic benefit of growing these crops for all the variants studied. Our research established that an increase in the bioenergy efficiency of the production of these crops is achieved due to the use of different rates of fertilizer application. The increase in productivity that was obtained as a result of the implementation of farming practices exceeds additional costs associated with the use of fertilizers. This confirms the economic benefit of producing these types of crops due to the enhanced bioenergy efficiency achieved through the optimal application of fertilizer.
The conducted research confirms the high energy efficiency of the bio-organic fertilizer (digestate) and the energy-saving technology of growing crops which were studied. High values of the coefficients of energy efficiency were also observed in the variants with the simultaneous application of mineral fertilizers (N90P90K90) and digestate-based bio-organic fertilizer “Efluent” (55.0 t/ha) on experimental sites of corn grown for grain (3.05–3.07), carrot (1.41–1.45) and red beet (1.97–2.00), but the cost of these variants also appeared to be the highest. Scientific research has used new methods and technologies for the effective processing of livestock waste in order to obtain organic fertilizer, which can be used to improve soil fertility and increase crop yields on the one hand, and biogas production as an energy-efficient process that has significant potential for producing ecologically clean and renewable energy on the other. The proposed approach to achieving energy efficiency helps to increase crop yield without increasing fertilization costs.

Abstract

This article analyzes the perspective of implementing target indicators in the green transition of the agro-industrial complex of Ukraine. It is established that soil degradation has acquired a global dimension, and it has become a serious problem of a socio-economic nature due to the military actions in Ukraine. Analysis of the state of agricultural land was performed based on the following indicators: humus content in the soil, volume of application of organic and mineral fertilizers, pesticides, land area under organic production, etc. The purpose of the study is to assess the impact of implementing waste-free biofuel production technologies at the enterprises of the agro-industrial complex to achieve eco-goals of the European Green Deal. The article outlines target guidelines for achieving eco-goals of the European Green Deal. Further steps necessary to overcome current problems in compliance with the norms of the EU legislation on environmental protection at agricultural enterprises for the sale of agricultural products to European markets are proposed. It has been scientifically proven that the agro-industrial complex of Ukraine has an untapped potential for reducing greenhouse gas emissions through ecological modernization and implementing waste-free production technologies. It is suggested to use biogas plants as a promising means of solving the problems of waste disposal, improving the ecological situation, reducing energy dependence, and increasing soil fertility. The effectiveness of applying organic fertilizer, namely digestate, a by-product of methane fermentation, as biofertilizers at agricultural enterprises has been proven. Recommendations are provided regarding soil regeneration measures in Ukraine in the future.
