Abstract
Abstract Soil acidification poses a significant challenge to soil health worldwide, and biochar emerges as a promising remedy. Nonetheless, a comprehensive evaluation of the impact of biochar on soil pH change is lacking, leaving considerable uncertainty regarding its efficacy across different environmental and management contexts. Here, we conducted a meta-analysis of 232 global studies to elucidate the impact of biochar on soil pH and identify key variables influencing its effectiveness. Our findings revealed that biochar application significantly increased soil pH by an average of 5.59%, but it decreased soil pH under certain circumstances. The raw material and pyrolysis temperature of biochar determine its…
