Biochar – a sustainable soil conditioner for improving soil health, crop production and environment under changing climate: a review

Frontiers in Soil Science, Journal Year: 2024, Volume and Issue: 4

Published: May 7, 2024

Land degradation and climate change, two intricately intertwined phenomena, demand appropriate management solutions to effectively tackle the escalating issues of food nutritional security. In this context, realm agriculture confronts formidable challenges in its pursuit soil resource reclamation, improving water quality, mitigating maintaining natural resources for posterity. Central these aspirations is preservation an optimum organic matter, serving as a linchpin threshold crucial protecting physical, chemical, biological integrity soil, while simultaneously sustaining agricultural productivity. To address multifaceted challenges, introduction diverse amendments has emerged strategy. Noteworthy among application biochar, which functions conditioner capable bolstering health, impact securing global Biochar carbon-enriched substance produced through pyrolysis assorted biomass waste. It larger surface area, higher cation exchange capacity, extended carbon storage capability. The strategic integration biochar production subsequent engenders array benefits, encompassing amelioration physical properties, augmented retention availability nutrients, enhancement activity, resulting yields societal benefits curtailment atmosphere greenhouse gas emissions. Additionally, demonstrates efficacy environmental restoration by medium extraction elimination heavy metals, often pervade aquatic ecosystems matrices. This review addressed need production, characterization, possibility restoration, crop yield fluctuations owing change.

Enhancing plant N uptake with biochar-based fertilizers: limitation of sorption and prospects

Plant and Soil, Journal Year: 2022, Volume and Issue: 475(1-2), P. 213 - 236

Published: March 24, 2022

Abstract Background Biochar-based fertilizer products (BCF) have been reported to increase both crop yield and N-use efficiency. Such positive effects are often assumed result from the slow-release of N adsorbed on BCF structures. However, a careful review literature suggests that actual mechanisms remain uncertain, which hampers development efficient products. Scope Here, we aim at reviewing responsible for enhanced uptake by plants, evaluate potential further improvement. We capacity biochar structures adsorb release forms, properties supporting this effect, methods proposed enhance effect. Conclusions Current show insufficient sorption retention forms support production BCFs high enough concentration. Substantial appear require conventional coating technology. Sorption can be improved through activation additives, but currently not extent needed concentrated BCFs. Positive commercial containing small amount pyrolysis-derived biostimulants. Our highlights three prospects improving retention: 1) NH 3 gas specifically activated biochar, 2) synergies between clay porosities, might provide economical enhancement, 3) physical loading solid within biochar. Beyond proof concept, quantitative nutrient studies ascertain future deliver expected use

Nitrogen availability in biochar-based fertilizers depending on activation treatment and nitrogen source

Waste Management, Journal Year: 2023, Volume and Issue: 158, P. 76 - 83

Published: Jan. 13, 2023

Different activation and N-doping treatments were used to produce biochar-based fertilizers (BBFs) with increased N concentration slow release. Pristine biochars produced by pyrolysis of olive tree pruning feedstock at low high temperatures (400 800 °C). These activated either ultrasonication, or oxidation hydrogen peroxide (H2O2) nitric acid (HNO3) increase their retention potential. Subsequently enriched urea ammonium sulfate. The low-temperature HNO3 was the most effective treatment leading new surface carboxylic groups that facilitated later enrichment N. When treated urea, BBFs reached 7.0 N%, whereas H2O2 only allowed an up 2.0 N%. use as external source efficient for incorporating Urea had a water-soluble fraction represented 14.5 % total hydrolyzable fraction, composed amides simple heterocycles originated treatments, nitro generated from activation, 60 This study relates chemical forms in potential availability soil. presence water-soluble, non-hydrolyzable implied these may supply would be progressively available plants, acting slow-release fertilizers.

Lignin-impregnated biochar assisted with microwave irradiation for CO2 capture: adsorption performance and mechanism

Biochar, Journal Year: 2024, Volume and Issue: 6(1)

Published: March 8, 2024

Abstract Bamboo biochar was modified by lignin impregnation and microwave irradiation to enhance its performance for CO 2 capture. The pore structure of lignin-impregnated significantly affected the ratio. maximum specific surface area 377.32 m g −1 micropore volume 0.163 cm 3 were observed on with an ratio 1:20 (mass biochar). Lignin increased adsorption capacity up 134.46 mg . Correlation analysis confirmed crucial role biochar’s in adsorption. Avrami model fitted capture curves well. calculation activation energy suggested that process dominated physical mechanism assisted partial chemical mechanism. Meanwhile, Langmuir isotherm indicated transformed larger pores into more uniform micropores, thereby making closer monolayer Both high reusability (89.79–99.06%) after 10 successive cycles excellent selectivity competitive is outstanding adsorbent Graphical
