Global Meta-analyses Review of Biochar in Agriculture

Improving soil microbiology and water retention, as well as increasing fertilizer efficiency, are some of the basic issues facing agricultural practices. The productivity of agricultural soils has long been increased by the use of synthetic fertilizers, some of which release greenhouse gases (GHG) into the atmosphere. A nutrient-rich product made from biomass, biochar is becoming more and more popular as a soil supplement to increase crop yields and sequester carbon. Biochar has been shown to be a helpful amendment in recent years for reducing greenhouse gas emissions from the soil to the environment and sequestering carbon. As a result, it may lessen the effects of climate change. According to certain research, adding biochar to agricultural soils boosts crop yields. Increased soil aeration and water-holding capacity, improved microbial activity and plant nutrient status in soil, and changes to some significant soil chemical properties are the mechanisms of biochar. Presenting a critical scientific analysis of the state of the art on how applying biochar affects the characteristics, operations, and functions of soil. The production and processing of biochar are contextualized with broader challenges, such as air pollution and occupational health and safety. The primary goals of this study are to suggest additional research on the use of biochar to soils and offer a solid scientific foundation for policy formation.
