Interpretive Summary: Biochar, a product of the pyrolysis of organic materials, is enriched with carbon and intended for application as a soil amendment, playing a key role in enhancing soil quality and carbon sequestration. Cotton byproduct-derived biochar has several advantages, including increased crop yields and reduced fertilizer requirements, soil carbon sequestration and soil remediation due to its high carbon content. Research findings indicate that combining cotton byproduct-derived modified biochar with an acrylate-based hydrogel through free radical polymerization creates a composite material featuring chitosan and ethylenediaminetetraacetic acid. This review focuses on the recent research activities of cotton byproduct-derived biochar and its impact on soil remediation and carbon sequestration. Inaddtion, the future research directions regarding cotton byproduct-derived biochar in soil environments are discussed. The knowledge and insights derived from this review would provide a sound scientific basis for promoting soil ecological restoration and carbon fixation.

Technical Abstract: Biochar can improve soil health and fix CO2 by improving soil microenvironment, thus impacting the global carbon cycle and the change of soil ecological environment. Recent studies show that cotton byproduct-derived biochar is a potential effective amendment for soil improvement so that it could play an important role in agricultural and environmental conservation. In this work, research topics on cotton byproduct-derived biochar in soil in last decade or so are systematically reviewed for better understanding of the progresses of cotton byproduct-derived biochar in (i) the morphologic and physicochemical characterization, (ii) latest research hotspots and trends, (iii) the roles in soil reclamation, and (iv) relevant carbon sequestration mechanisms. Finally, the future research directives regarding cotton byproduct-derived biochar in soil environments are discussed. Insight derived from this work would provide scientific basis for promoting more applications of cotton byproduct-derived biochar in soil ecological restoration and carbon fixation.
