Abstract:

Biochar can improve soil structure and properties when applied as a soil amendment. The biochar-based fertilizers made by mixing biochar with nutrients has the advantages of delayed nutrient release and reduced nutrient leaching, which is an environmentally friendly fertilizer with great application potential in agriculture. Studies have shown that the application of biochar and biochar-based fertilizers can effectively improve the physical and chemical properties of soil, increase the abundance of soil microorganisms, and promote plant growth. In the present study, the research progress of biochar and biochar-based fertilizers in agriculture in terms of their effects on soil physical and chemical properties, soil microbial communities, plant growth and nutrient uptake was reviewed, and prospects for the application of biochar and biochar-based fertilizers in agriculture were proposed.

Key words: biochar, biochar-based fertilizer, soil quality, plant growth, research progress
