The global impact of water and soil contamination has become a serious issue that affects the world all living beings. In this sense, multiple treatment alternatives have been developed at different scales to improve quality. Among them, biochar suitable alternative for environmental remediation due its high efficiency low cost, raw material used production comes from residual biomass. A is carbonaceous with interesting physicochemical properties (e.g., surface area, porosity, functional groups), which can be prepared by synthesis methods using agricultural wastes (branches banana rachis, cocoa shells, cane bagasse, among others) as feedstock. This state-of-the-art review based on general description remediation. Biochar’s production, synthesis, uses also analyzed. addition, work shows some thus several applications, like removing heavy metals, oil, dyes, other toxic pollutants.

Biochar and organic fertilizer drive the bacterial community to improve the productivity and quality of Sophora tonkinensis in cadmium-contaminated soil

Frontiers in Microbiology, Journal Year: 2024, Volume and Issue: 14

Published: Jan. 8, 2024

Excessive Cd accumulation in soil reduces the production of numerous plants, such as Sophora tonkinensis Gagnep., which is an important and widely cultivated medicinal plant whose roots rhizomes are used traditional Chinese medicine. Applying a mixture biochar organic fertilizers improved overall health Cd-contaminated increased yield quality . However, underlying mechanism between this mixed fertilization improvement remains uncovered. This study investigated effect fertilizer application (BO, to ratio 1:2) on growth soil. BO significantly reduced total content (TCd) rhizosphere water content, nutrient levels, enzyme activities Additionally, α diversity bacterial community had been after treatment. Soil pH, carbon dissolved were main reasons for fluctuation dominant species. Further investigation demonstrated that abundance variable microorganisms, including Acidobacteria, Proteobacteria, Bacteroidetes, Firmicutes, Chloroflexi, Gemmatimonadetes, Patescibacteria, Armatimonadetes, Subgroups_ 6, Bacillus Bacillus_ Acidiceler , was also changed All these alterations could contribute reduction and, thus, increase biomass secondary metabolites (matrine oxymatrine) Our research co-application has potential enhance productivity plants by regulating microorganisms

Biochar Addition Reduces the Effect of High Nitrogen on Soil–Microbial Stoichiometric Imbalance in Abandoned Grassland on the Loess Plateau of China

Ecology and Evolution, Journal Year: 2025, Volume and Issue: 15(2)

Published: Jan. 30, 2025

ABSTRACT Progressively higher atmospheric nitrogen (N) deposition increasingly affects soil ecosystems' elemental cycling and stability. Biochar (BC) amendment has emerged as a possible means of preserving system Nevertheless, the pattern soil–microbial nutrient stability in response to BC after high N ecologically sensitive regions remains uncertain. Therefore, we investigated effects (9 g N·m −2 ·a −1 ), (0, 20, 40 t·ha combinations treatments on organic carbon (SOC), total (TN), phosphorus (TP), microbial biomass (MBC), (MBN), (MBP), entropy ( q MB stoichiometric imbalance (C imb :N :P ). We found that addition decreased topsoil (0–20 cm) TP, C:N, MBN , C values increased TN, C:P, N:P, MBP values. However, 0–40 cm MBC Meanwhile, additions attenuated BC's promotion nutrients. observed mixture SOC TP content, promoted accumulation subsoil (20–40 cm), compared additions. The impact P elements varied significantly between different depths. In addition, redundancy analysis identified MBC, MBN, C:P pivotal factors affecting alterations imbalance. Overall, adding reduced negative impacts systems Loess Plateau, suggesting new approach for managing fragile areas.
