摘要

This study presents a comprehensive scientometric analysis of the use of biochar in plant growing media between 2011 and 2024. Bibliometric analysis tools (VOSviewer and Bibliometrix) were applied to map patterns of scientific collaboration, authors, institutions, and global thematic trends based on publications retrieved from the Web of Science platform. The analysis comprised 973 publications and revealed exponential growth in scientific output, with a strong positive linear trend from 2020 to 2024 (R² = 0.95) and a peak of 169 publications in 2024. China led global production and impact with 297 articles and 11,407 citations, followed by the United States with 122 articles and 4,197 citations, while the Chinese Academy of Sciences ranked as the most relevant institution with 28 publications and 1,097 citations. The most frequent terms were “biochar” (537 occurrences), “soil” (200), “compost” (163), and “growth” (162), reinforcing the role of biochar in improving substrate properties, promoting plant development, and supporting sustainable alternatives to peat. Biochar represents a promising solution for formulating sustainable growing substrates, although the standardization of production methods and the understanding of its interactions with plants and microorganisms remain challenges for future research.
