A study published in EurekAlert, USA, reported that hydrochar made from wet biomass, can improve soil structure and increase soil carbon storage more effectively than some common organic amendments.
It enhances stable soil aggregates, helping soils retain water, nutrients, and resist erosion while protecting stored carbon.Different feedstocks influence performance: manure-based hydrochar boosts nutrients, while stalk-based types improve carbon retention and stability. The study suggests hydrochar could be a customizable, climate-smart soil amendment for healthier and more resilient croplands.
