Itam, et al (2024) Application of biocharBiochar is a carbon-rich material created from biomass decomposition in low-oxygen conditions. It has important applications in environmental remediation, soil improvement, agriculture, carbon sequestration, energy storage, and sustainable materials, promoting efficiency and reducing waste in various contexts while addressing climate change challenges.

The study “Application of Biochar in Soil Remediation: A Decade of Scientometrics and Systematic Review from 2014 to 2024” provides a thorough analysis of biochar’s role in improving soil quality and addressing contamination. Over the past decade, biochar has gained traction as a sustainable amendment for soil remediation, particularly in China, which leads global research efforts.

Biochar’s efficacy stems from its ability to retain nutrients, increase soil pHpH is a measure of how acidic or alkaline a substance is. A pH of 7 is neutral, while lower pH values indicate acidity and higher values indicate alkalinity. Biochars are normally alkaline and can influence soil pH, often increasing it, which can be beneficial More, and enhance microbial activity. The material shows promise in immobilizing pollutants like heavy metals and organic contaminants, improving soil health across varied environments. For instance, biochar-supported nano-scale zero-valent iron (nZVI) has been shown to significantly degrade contaminants, while biochar from animal waste exhibits high biostimulatory properties.

The review highlights that biochar’s effectiveness is contingent on several factors, including the type of biochar, soil characteristics, and pyrolysis conditionsThe conditions under which pyrolysis takes place, such as temperature, heating rate, and residence time, can significantly affect the properties of the biochar produced.   More. Researchers emphasize the need for further studies to validate biochar’s application across different soil types and climatic regions.

While the field has seen significant growth, the study also notes a decline in publication activity in 2024, calling for continued exploration and broader adoption of biochar in sustainable land management and environmental conservation efforts. As biochar demonstrates potential in improving soil health and reducing pollution, future research should focus on its long-term effects and practical applications in diverse agricultural contexts.
