Abstract: This study addresses the urgent need for solutions to mitigate the adverse impacts of industrial agriculture exacerbated by climate change. Focusing on soil health improvement as a remedy, particularly through the use of biochar, a soil amendment. The research investigates the influence of different biochar particle sizes on microbial respiration when inoculated with effective microorganisms (EM1). The study hypothesizes that the smallest particle size of biochar will yield the highest microbial response in terms of CO2 flux. The results, obtained through two trials, reveal a nuanced relationship between particle size and microbial activity. Although the 2-4mm particle size consistently exhibited the highest CO2 flux, smaller sizes, such as <2mm, showed increased inoculant retention, potentially leading to waterlogged conditions and decreased microbial activity. Overall, biochar, regardless of particle size, outperformed inoculated soil in promoting microbial activity, affirming its potential as a soil amendment and microbial carrier. The study emphasizes biochar's promise for enhancing soil health, crop productivity, and the sustainability of future food systems, particularly when used in combination with microbial inoculants.
