Biochar, a carbon-rich material created from pyrolyzed biomass, is being used to combat soil degradation and heavy metal contamination in tea plantations. By stabilizing soil pH and improving nutrient retention, it reduces the need for chemical fertilizers and helps sequester carbon in the ground. Research shows that biochar improves root growth and leaf biomass while immobilizing toxic metals like lead and cadmium. This process not only enhances crop yields and tea quality but also creates a more resilient agricultural system against climate stress.
