Summary: This review explores the use of biochar as an effective additive for improving low-fertility soils and promoting plant growth. It discusses the methods and conditions for biochar production, as well as the effects of pyrolysis temperature, feedstock type, and retention time on the properties of biochar. The review also highlights the various ways in which biochar can enhance soil physical and chemical properties, improve plant nutrient uptake and growth, reduce greenhouse gas emissions, minimize plant diseases, and facilitate the remediation of heavy metal-contaminated soils. The possible mechanisms for biochar-induced soil and plant improvement are described, and the challenges associated with biochar utilization are discussed.

Summary: Biochar has gained attention as an integrated solution for agricultural waste recycling, soil improvement, carbon sequestration, and greenhouse gas reduction. However, the environmental benefits of biochar are hindered by its limited use in soil management, due to a lack of understanding and promotion. This review article discusses biochar applications in agricultural soil systems, focusing on carbon-neutral strategies and the importance of effective agricultural management for carbon sequestration.

Summary: Biochar plays a useful role in agriculture by improving soil structure, nutrient availability, water retention, and reducing the negative impact of pesticides and heavy metals. Careful consideration of parameters such as biochar origin, pyrolysis temperature, soil type, and application rate is important for maximizing biochar's efficiency and preventing adverse effects on the agricultural environment.

Summary: In this study, biochar was prepared using waste dander and CaSa(4) was generated on its surface to enhance soil carbon sequestration ability. The results showed that the application of Ca-BC reduced soil organic carbon mineralization rate, increased soil moisture content and organic carbon content. Bioinformatics analysis also revealed a shift in bacterial phyla with the application of Ca-BC.

Summary: Biochar is a promising carbonaceous material with abundant functional groups and mesoporous structure, showing potential in improving soil fertility, retaining nutrients, enhancing microbial activity, and immobilizing contaminants. The dissolved organic matter (DOM) from biochar plays a key role in soil matrix, microbial community, and fate of contaminants, with both positive and negative effects that are influenced by various factors such as the nature of biochar-derived DOM and environmental conditions. Understanding the long-term stability and interactions of biochar-derived DOM is critical for minimizing the ecological and environmental risks of biochar application.

Summary: Biochar, characterized by Fourier-transform infrared spectroscopy, scanning electron microscopy with energy dispersive X-ray (SEM-EDX), and X-ray diffraction analytical techniques, was found to significantly decrease the disease index of eggplants infected with bacterial wilt. The increase in chlorophyll content and biochemicals such as phenolics, flavonoids, and peroxidases induced by biochar contributed to the resistance response against the disease. Additionally, biochar also affected the levels of NPK in eggplants.

Summary: The increase in mineral and ash-rich waste biomass generation in emerging economies poses critical environmental problems and bottlenecks the solid waste and wastewater treatment systems. Transforming these waste biomasses to biochar through pyrolysis can be a sustainable method for their disposal and resource recovery. However, the limited organic content and possibly contaminated nature of the waste biomasses may restrict the applicability of the biochar. This study investigates the physicochemical properties and carbon sequestration potential of biochar derived from the co-pyrolysis of sewage sludge with other waste biomasses, and explores its potential benefits in soil improvement and heavy metal reduction.

Summary: The study developed an Fe/Al (hydr)oxides modified biochar (FA-BC) to reduce P leaching in calcareous soils, demonstrating its higher efficiency in P adsorption compared to raw biochar. The application of FA-BC significantly decreased total P leaching, while maintaining adequate levels of bioavailable P in the soil. Chemical sequestration tests and analyses further showed the transformation of labile Ca-P fractions into stabilized Fe/Al-P complexes, highlighting the superior P retention ability of FA-BC amended soils.

Summary: The increasing rates of waste generation due to population growth, urbanization, and consumption patterns have raised concerns about waste management on a global scale. Lignocellulosic biomass is a significant portion of agricultural, agro-industrial, and municipal waste. Butanol, a biofuel with compatibility to existing fuel infrastructure, lower volatility, and higher energy density, has emerged as a promising alternative. This review highlights the sustainable management of lignocellulosic biomass waste and the utilization of clostridia as a microbial catalyst for the production of butanol, with a focus on recent advancements in strain development and future prospects.
