Biochar application is a promising strategy for the remediation of contaminated soil, while ensuring sustainable waste management. heavy metal (HM)-contaminated soil primarily depends on properties biochar, and HM. The optimum conditions HM immobilization in biochar-amended soils are site-specific vary among studies. Therefore, generalized approach to predict efficiency required. This study employs machine learning (ML) approaches biochar soils. nitrogen content (0.3–25.9%) rate (0.5–10%) were two most significant features affecting immobilization. Causal analysis showed that empirical categories efficiency, order importance, > experimental properties. this presents new insights into effects can help determine enhanced

Formation of soil organic carbon pool is regulated by the structure of dissolved organic matter and microbial carbon pump efficacy: A decadal study comparing different carbon management strategies

Global Change Biology, Journal Year: 2023, Volume and Issue: 29(18), P. 5445 - 5459

Published: July 9, 2023

To achieve long-term increases in soil organic carbon (SOC) storage, it is essential to understand the effects of management strategies on SOC formation pathways, particularly through changes microbial necromass (MNC) and dissolved (DOC). Using a 14-year field study, we demonstrate that both biochar maize straw lifted ceiling, but different pathways. Biochar, while raising DOC content, decreased substrate degradability by increasing aromaticity. This resulted suppressed abundance enzyme activity, which lowered respiration, weakened vivo turnover ex modification for MNC production (i.e., low pump "efficacy"), led lower efficiency decomposing MNC, ultimately resulting net accumulation MNC. In contrast, incorporation increased content aromaticity DOC. The enhanced nutrient such as total nitrogen phosphorous, stimulated population thereby boosting respiration enhancing "efficacy" production. C added plots were estimated 27.3-54.5 41.4 Mg ha-1 , respectively. Our results demonstrated was more efficient lifting stock via exogenous stable input stabilization, although latter showed "efficacy". Meanwhile, significantly promoted also mineralization, smaller increase (by 50%) compared 53%-102%). address decadal-scale application pool soil, understanding causal mechanisms can allow practices maximize content.
