Stability of Material from Hydrothermal Humification of Biomass in Soil

Abstract:

hydrothermal humification (HTH) is a novel way to treat biomass in order to produce soil conditioner or organic fertilizer. The incubations were performed in about 200mL pots which were either filled with mixtures HTH material and soil (1:3, wt:wt).The several studies were carried out to investigate how HTH materials derived from lawn-grass, pine-branch, and pine-needle interact with existing organic matter in soils. Compared with natural soil, C/N and lignin residue changes of incubated materials were analyzed during incubation. The results show that although the C/N and lignin residue decreased across incubation, HTH addition hadn’t a significant effect on activity of microorganism, indicating a more efficient stability of HTH in soil.
