Abstract

Biochar (BC) is a carbon-rich material created from biomass pyrolysis. It is an efficient addition for reducing ammonia inhibition due to its large specific surface area, porosity, conductivity, redox characteristics, and functional groups making it favorable for both soil and water remediation. The efficacy of biochar on the N cycle is associated with biochar properties which are mainly affected by feedstock type and pyrolysis condition. The addition of BC to soil affects nitrogen adsorption pathways. Other advantages include improved soil fertility, nutrient immobilization, and slow-release carbon storage. Biochar adsorption of ammonia reduces ammonia (NH₃) and nitrate (NO₃) losses during composting after manure applications and provides a method for creating slow-release fertilizers. Depending on the N source and the properties of the biochar, NH₃ loss reductions vary. Besides improving soil dynamics, BC can also be used in wastewater treatment. Engineered or designer biochar is positioned as a promising material for wastewater treatment due to its enhanced properties and versatility.

期刊介绍： Biodegradation publishes papers, reviews and mini-reviews on the biotransformation, mineralization, detoxification, recycling, amelioration or treatment of chemicals or waste materials by naturally-occurring microbial strains, microbial associations, or recombinant organisms. Coverage spans a range of topics, including Biochemistry of biodegradative pathways; Genetics of biodegradative organisms and development of recombinant biodegrading organisms; Molecular biology-based studies of biodegradative microbial communities; Enhancement of naturally-occurring biodegradative properties and activities. Also featured are novel applications of biodegradation and biotransformation technology, to soil, water, sewage, heavy metals and radionuclides, organohalogens, high-COD wastes, straight-, branched-chain and aromatic hydrocarbons; Coverage extends to design and scale-up of laboratory processes and bioreactor systems. Also offered are papers on economic and legal aspects of biological treatment of waste.
