Carbon Mineralization Dynamics of Organic Materials and Their Usage in the Restoration of Degraded Tropical Tea-Growing Soil

Understanding carbon mineralization dynamics of organic amendments is essential to restore degraded lands. This study focused on the restoration potentials tea-growing soils using materials available in tea ecosystems. The Selangor-Briah soil series association (Typic Endoaquepts) consisted a high- (soil A) and low-carbon B) were incubated with different released dioxide (CO2) measured. Two kinetic models applied depict process. Soil health parameters including microbial biomass nitrogen, dehydrogenase catalase activities determined assess potentials. parallel first-order model fitted well for all amendments. Gliricidia markedly enhanced net cumulative CO2 flux both soils. Charged biochar, waste improved by 79–84% A 82–93% B, respectively. Microbial quotients nitrogen increased over 50 70% amended soils, Dehydrogenase activity was significantly accelerated 80% compost, charged biochar waste. remarkably 141%. biomass, activities, positively correlated (r > 0.452) one another. studied showed greater potential improving quality, while raw compost enrich recalcitrant C pool ensuring long term. Even though sequesters carbon, it has be nutrients achieve goals.
