TL;DR: In this paper, a microcosm study with a water-saturated soil amended with different amounts (0, 2% and 10% (w/w)) of high-temperature biochar was performed.

TL;DR: It is found that biochar addition enhanced microbial nitrous oxide reduction and increased the abundance of microorganisms capable of N2-fixation, suggesting a mechanistic link to the observed reduction in N2O emissions.

TL;DR: In this paper, the authors demonstrate that biochar concentrations of 5 and 10 g L−1 stimulate both the rate and the extent of microbial reduction of the Fe(III) oxyhydroxide mineral ferrihydrite (15 mM) by Shewanella oneidensis MR-1.

TL;DR: This work identifies a complex, nutrient-rich organic coating on co-composted biochar that covers the outer and inner (pore) surfaces of biochar particles using high-resolution spectro(micro)scopy and mass spectrometry, which strengthens biochar-water interactions and thus enhances nutrient retention.

TL;DR: Soil biochar amendment significantly altered the 16S rRNA gene-based community composition and structure and led to the development of distinct functional traits capable of N2O reduction containing typical and atypical nosZ genes related to nos Z genes found in Pseudomonas stutzeri and Pedobacter saltans.
