Abstract
Biochar might have a synergistic interaction with fertilizers and can be used to produce biochar-based fertilizers (BBF) of enhanced efficiency. There are different routes to produce such BBF, such as direct pyrolysis of nutrient-rich feedstock, impregnation of biochar with nutrients, co-pyrolysis of nutrient-enriched feedstock, reuse of nutrient-loaded biochar after adsorption, and activated nutrient-loaded biochar. Here, we explore the routes to produce BBF and the mechanisms of nutrient release from these novel materials. We also evaluate the use of biochar in the process of co-composting and its use as a soil amendment, the use of biochar in growing media, and discuss biochar-based foliar sprays and liquid fertilizers. Finally, we make recommendations for product development and point out future research needs.
