Biochar & carbon allocation in the soil: sorb, protect, repeat ♻️🌱

📰 A new research by Weng et al. 2022 (Nature Communications) assessed the capacity and mechanisms by which biochar builds new biogenic soil organic carbon (SOC) reserves.

📊 Researchers confirmed that biochar application of Eucalyptus saligna can contribute to reduced mineralization of native SOC by 18% in the subtropical pasture.

⚙️ Authors provide a brilliant description of the formation of protected SOC aggregates:

1) 🌱 Biochar sorbs root-derived carbon onto its surface, protecting the rhizodeposits from immediate microbial consumption.

2) 🦠 Microbial necromass also adsorbs to biochar being retained in similar protective interfaces.

3) ♻️ The process repeats, to develop a new, protected SOC over time.
