Influence of carbonised biomass on soil improvement, increase in yield of agricultural crops and mitigation of climate change implications

Abstract

The relevance of the study is conditioned by the need to develop and implement new technological solutions for tillage, which will improve the soil properties. The purpose of this study is to assess the impact of carbonised biomass on the properties and quality of soils, as well as the associated environmental consequences. The tasks addressed by the study were solved with the help of scientific theoretical methods: analysis, systematisation and generalisation of results. The scientific works related to the problem of the influence of carbonised biomass on soil quality were analysed in this paper. An assessment of the effectiveness of its use as an organic ameliorant and its effect on improving the agronomic properties of soils, their fertility, and on the ecological situation has been carried out. It is substantiated that the use of obsolete agricultural technologies during agricultural activities and their violation have a negative impact on soil fertility and increase in greenhouse gases in the atmosphere. It is argued that this could lead to a global food crisis. It has been emphasised that due to the use of biochar as an organic ameliorant the physical and microbiological properties of soils are improved, the availability of nutrients is optimised, and the content of toxic elements is reduced. It is shown that carbonised biomass has a positive effect on yields and also helps to reduce greenhouse gas emissions into the atmosphere. The main current problems that exist in Ukraine regarding the use of soil improvement technology with the help of carbonised biomass are identified. The ways of their solution for the further development of these technologies and their implementation in the agro-industrial sector are proposed. The practical value of the study consists in determining the effectiveness of using carbonised biomass when it is introduced into the soil to improve its quality, increase crop yields, and slow down climate change
