In recent years, the intersection of biocharBiochar is a carbon-rich material created from biomass decomposition in low-oxygen conditions. It has important applications in environmental remediation, soil improvement, agriculture, carbon sequestration, energy storage, and sustainable materials, promoting efficiency and reducing waste in various contexts while addressing climate change challenges. More (BC) and humic substances (HSs) has emerged as a promising avenue for sustainable agriculture and environmental management. This research, conducted as part of the Innovative PhD program in Environmental Sustainability and Wellbeing at the University of Ferrara, Italy, under the supervision of Prof. Dr. Silvia Rita Stazi, and coordinated by Prof. Dr. Paola Spinozzi, explores the transformative potential of aged biochar.

Biochar aged or combined with humic substances: fabrication and implications for sustainable agriculture and environment-a review

This first paper focuses on the fabrication and implications of BC aged or combined with HSs, highlighting their critical role in enhancing soil health, fertility, and overall environmental sustainability. The study employs a novel technique to investigate the aging process of BC with HSs, revealing that aged biochar surpasses its fresh counterpart in improving nutrient pools, pollutant removal, and plant performance. Understanding the intricate relationship between BC aging and HSs is deemed crucial for optimizing their impact on agro-environmental systems.

Research Trend of Aging Biochar for Agro-environmental Applications: a Bibliometric Data Analysis and Visualization of the Last Decade (2011–2023)

This second paper employs a bibliometric analysis to scrutinize the research trends of aged-biochar for sustainable agro-environmental applications over the last decade. With 165 high-quality publications between 2011 and 2023, the analysis identifies key research frontiers, including biochar production from diverse biomassBiomass is a complex biological organic or non-organic solid product derived from living or recently living organism and available naturally. Various types of wastes such as animal manure, waste paper, sludge and many industrial wastes are also treated as biomass because like natural biomass these More resources, the influence of (a)biotic factors on aging, and the multifaceted effects on global climate change, soil nutrient dynamics, and plant growth. Despite notable progress, the study underscores the need for continued attention and exploration to fully harness the potential of aged biochar.

These papers collectively underscore the transformative power of aged biochar in promoting sustainable agriculture, environmental sustainability, wellbeing, and a circular bioeconomy. The innovative techniques and data-driven analyses presented pave the way for future research and applications, emphasizing the importance of ongoing exploration in this promising field.
