The study focuses on utilizing M×g biomass and its processed products (biochar, ash) to restore soil fertility, sequester carbon, reduce greenhouse gas emissions, and enhance ecosystem resilience. The work involves evaluating the effectiveness of phytotechnologies in remediating soils contaminated with heavy metals and organic pollutants, as well as their contribution to climate change adaptation on territories previously used for military purposes. popup.description2 Object of research: The restoration processes of soils damaged by military actions using by-products from the processing of the energy crop Miscanthus x giganteus (M×g) biomass—biochar and ash. Goal: To develop science-based recommendations for implementing M×g-based phytotechnology for the ecological regeneration of military lands in Ukraine and climate change mitigation. Methods: Physico-chemical analysis of soils and by-products (X-ray fluorescence, CHNS/O elemental analysis), controlled vegetation experiments, field monitoring, spectrophotometry, fluorometry, statistical analysis. Results and novelty: A comprehensive study of the impact of biochar and ash on the "soil-plant" system was conducted. It was found that ash at low application rates (1–3%) improves soil fertility, while high rates (5–7%) cause nutrient imbalances. For the first time, a comparative analysis of commercial biochars revealed their opposite effects on nitrogen dynamics: biochar from biomass waste (IDL type) at a 3% rate stimulated maize growth, whereas wood-derived biochar (INT type) inhibited growth due to nitrate adsorption. Biochar from Miscanthus produced at 600°C showed high stability and sorption capacity, which was confirmed by a patent. In field conditions on military lands (Vorzel), biochar application improved M×g growth and soil fauna structure. Effectiveness and application area: A technology and recommendations for the sustainable restoration of damaged lands have been developed. The technology can be implemented in the agro-industrial complex, in programs of the Ministry of Defence of Ukraine, and local self-government bodies to enhance environmental and food security.
