Carbon sequestration potential of hydrothermal carbonization char (hydrochar) in two contrasting soils; results of a 1-year field study

Soil amendment with hydrochar produced by hydrothermal carbonization of biomass is suggested as a simple, cheap, and effective method for increasing soil C. We traced C derived from corn silage hydrochar (δ¹³C of −13 ‰) added to “coarse” and “fine” textured soils (δ¹³C of −27 ‰ for native soil C (SO...

Zusammenfassung:Soil amendment with hydrochar produced by hydrothermal carbonization of biomass is suggested as a simple, cheap, and effective method for increasing soil C. We traced C derived from corn silage hydrochar (δ¹³C of −13 ‰) added to “coarse” and “fine” textured soils (δ¹³C of −27 ‰ for native soil C (SOC)) over two cropping seasons. Respiration rates increased in both soils (p
