Biochar is the solid material formed from the thermal conversion of biomass feedstocks under oxygen-limited conditions. Biochar is known for its highly developed porous structures, rich functional groups diversified inorganic nutrients, and high carbon stability. The use of biochar composite as a soil amendment has great potential due to its numerous beneficial qualities in the domains of agriculture and environmental remediation. Recently, there has been a growing recognition of the significance of soil health in the sustainable utilization of crucial soil resources and the resolution of soil limits. This recognition has sparked a global shift in traditional soil usage and management practices towards more sustainable strategies. Thus, the use of engineered biochar composites has attracted considerable attention in recent years. Our study reveals four distinct and important issues that require focused attention in future research initiatives. This presents a visual depiction of a particular notion or phenomenon. An important observation in the field is the remarkable simplicity with which biochar composites can be synthesized.
