Abstract
Refined physiochemical characteristics and sustainable nature make engineered biochar a perfect choice to tackle different agricultural issues in the present circumstances. Multifaceted functional groups with stable C-matrix can serve as a superior carrier for essential nutrients, thereby revamping nutrient use efficiency (NUE). Apart from NUE, engineered biochar�s are excellent as an alternative to fight against climate change and sequester atmospheric carbon-di-oxide (CO2). It improves soil aeration and prevents the formation of methane (CH4). Also, researchers reported a high C:N ratio in modified biochar combat nitrous oxide emission by (N2O) curtailing greenhouse gas (GHG) emission. But, due to constraints from production technology and the environmental applications point of view scientists have tried different avenues like co-composting, co-pyrolysis or introducing polymers for making biochar-based slow-release fertilizer (BSRF), but loopholes are still there. However, long-term on-field evaluation, production feasibility and sustainability need to be studied extensively besides manufacturing and characterizing these biochar-based products. Therefore, in this present chapter, an endeavor has been made to summarize important aspects of engineered biochar�s like production technology and physiochemical properties. Also, a detailed discussion has been made regarding the application of engineered biochar to improve nutrient use efficacy and combat climate change. Therefore, in a nutshell for sustainable agriculture and climate change mitigation, engineered biochars are potent options in years to come. � 2024 by Elsevier Inc.
