Biochar Applications for Sustainable Agriculture and Environmental Management
AI summary Read the abstract
This review examines the applications of biochar in sustainable agriculture and environmental management, covering its use as a soil amendment to address emerging pollutants such as microplastics and pharmaceutical waste, reduce salinity and drought stress, and sequester carbon. The review synthesizes research on how biochar feedstock type and thermal conversion technique influence its physicochemical properties and effects on soil microbial communities and nutrient cycling.
Application of biochar in agriculture is a tried-and-true technology and established technique to solve several sustainability-related issues in the field of agriculture. Biochar for environmentally friendly farming practices and usage of biochar to manage soil sustainably has been recommended. The biodegradable biomass is the most typically utilized feedstock for biochar production. Benefits and drawbacks of using bio-based waste substrates to restore deteriorated soil when "emerging pollutants" such microplastics and pharmaceutical waste are involved are covered. The causes of soil deterioration and the advantages of biochar for the atmosphere and soil benefits for less emissions and carbon neutrality has been reviewed. Depending on various sources of feedstock and conversion techniques, biochar, and other byproducts of the thermal conversion of biomass are discussed. For environmentally friendly farming and sustainable agriculture, the biogeochemical cycling of nutrients is greatly influenced by soil microorganisms. The addition of biochar to soil in agroecosystems affects the soil biota and physicochemical characteristics. The interaction of the soil microbial population with the dynamics of the soil's organic matter is known as soil carbon sequestration. An annotated summary of research results is tabulated for the effects of biochar on the detoxification of potentially toxic elements in soil, the reduction of salinity in various crop fields, the reduction of drought in croplands, and other uses of biochar for long-term soil sustainability.

Advances and prospects of biochar in improving soil fertility, biochemical quality, and environmental applications
AI summary Read the abstract
This review examines how biochar, a charcoal-like material made from organic waste, can improve soil health and clean up pollutants including microplastics. Biochar's ability to absorb and trap contaminants makes it a promising tool for reducing microplastic pollution in agricultural soil. The findings suggest biochar could help limit the amount of microplastics that enter the food chain through crops grown in contaminated soil.
Biochar as an Environment-Friendly Alternative for Multiple Applications
AI summary Read the abstract
This review summarizes how biochar, a charcoal-like material made from plant waste, can be used for carbon storage, improving soil health, and reducing greenhouse gas emissions. Notably, biochar shows potential for reducing microplastic and heavy metal contamination in soil by binding these pollutants and preventing them from being absorbed by crops. This makes biochar a promising tool for protecting food safety in agricultural soils contaminated with microplastics.
Biochar as a Climate-Smart Approach for Soil Health Improvement and Nano-/Microplastic Mitigation in Sustainable Agriculture: A Review
AI summary Read the abstract
Tiny plastic particles are building up in farm soils, potentially getting absorbed by crops we eat—but this review of existing research suggests that biochar (a charcoal-like material made from organic waste) can act like a sponge to trap these plastics in soil before they reach our food. It also improves soil quality and helps fight climate change, though scientists still need more research to understand its limits, especially in certain soil types.
