The application of biochar as a soil amendment has garnered significant interest due to its potential enhance fertility, promote plant growth, and contribute sustainable agriculture. This study investigated how the structural morphological characteristics artisanal biochars from four different brands (AB1, AB2, AB3, AB4), purchased in supermarkets, influence development rice plants sandy soil. Spectroscopic analyses demonstrated that AB4 exhibited highest aromaticity (77%), ensuring stability, whereas AB2 displayed greater aliphaticity (47%). Morphological characterization revealed preserved cellular structure original biomass. studied doses influenced parameters evaluated differently. with aromatic (AB4) promoted an increase root area, length, number bifurcations, well dry fresh nutrient accumulation aerial part was AB1 at dose 10 t ha−1. Chlorophyll fluorescence analysis indicated improved photosynthetic performance treatment, mitigating initial stress optimizing energy use. underscores crop productivity foster agricultural practices.

Mechanisms of Cu2+ Immobilization Using Carbonyl Iron Powder–Biochar Composites for Remediating Acidic Soils from Copper Sulfide Mining Areas

Sustainability, Год журнала: 2025, Номер 17(10), С. 4281 - 4281

Soil heavy metal contamination poses critical challenges to ecological sustainability in mining regions, particularly acidic soils from copper sulfide mines. This study developed a sustainable remediation strategy using carbonyl iron powder–biochar composite (CIP@BC) derived agricultural waste (rice husk) and industrial byproducts. The was synthesized through an energy-efficient mechanical grinding method at 10:1 mass ratio of biochar powder, aligning with circular economy principles. Material characterization revealed CIP particles uniformly embedded within biochar’s porous structure, synergistically enhancing surface functionality redox activity. CIP@BC demonstrated exceptional Cu2+ immobilization capacity (910.5 mg·g−1), achieved chemisorption monolayer adsorption mechanisms. Notably, the process concurrently improved key soil health parameters. incubation trials that 6% application elevated pH 4.27 6.19, reduced total Cu content by 29.43%, decreased DTPA-extractable 67.26%. treatment effectively transformed speciation bioavailable residual fractions. Concurrent improvements electrical conductivity (EC), cation exchange (CEC), organic matter (OM), water (SWC) collectively highlighted composite’s multifunctional potential. bridges environmental land management innovative waste-to-resource approach remediates mine soils. dual contaminant quality restoration provides scalable solution.
