Biochar and Soil Bacteria Working Together to Enhance Carbon Storage in Soil
A study published in Biochar Journal, China by Shenyang Agricultural University reports that the biochar, when modified with minerals and different heating temperatures, can influence soil bacteria and improve carbon storage in agricultural soils. Biochar is made from plant waste and can either increase or reduce carbon loss depending on how it is produced and the type of soil. Researchers found that higher-temperature biochar with vermiculite helped reduce carbon loss in red soils. In paddy soils, all biochar types reduced carbon loss, with mid-temperature biochar showing the strongest effect. The study suggests that designing biochar properly can help reduce CO₂ emissions and support climate-smart farming.

Hydrochar as an effective amendment for enhancing soil aggregation and carbon sequestration
A study published in Biochar Today Journal by Technologies Research and Development Program of China and Research paper by Sun et al shows that hydrochar can significantly improve soil organic carbon (SOC) storage and soil aggregate stability, outperforming traditional amendments like straw and biochar. Hydrochar made from different feedstocks showed varying effects, with Zanthoxylum stalk–derived hydrochar performing the best. It increased soil carbon levels and improved soil structure by enhancing macro-aggregates and stabilizing carbon in organic matter. Microbial activity and carbon type played key roles in how hydrochar affected soil health and carbon sequestration. The study highlights that choosing the right feedstock is important for maximizing hydrochar’s benefits for sustainable agriculture.
