Researchers have found that hydrochar, created from wet biomass through hydrothermal carbonization, enhances soil structure and carbon storage more effectively than traditional organic amendments. The study highlights how different feedstocks, such as maize straw and pig manure, can be used to target specific agricultural goals like nutrient supply or long term carbon retention. By increasing the proportion of stable soil macroaggregates, hydrochar helps protect organic carbon from rapid decomposition. This process offers a scalable way to transform livestock and crop residues into tools for climate smart soil management and improved cropland resilience.
