Biochar application to soils can regulate soil phosphorus availability: a review

Abstract Phosphorus (P) is essential for basic natural processes and can limit the productivity of entire ecosystems. However, agricultural lands worldwide currently suffer from P deficiency. The application of P fertilizers is not only poorly utilized, but also results in the gradual accumulation of P. Biochar, a substance produced by the pyrolysis of biomass under low oxygen levels, is frequently used as a soil amendment. It provides P in a form that is readily available for plant uptake, and thus addresses both short- and long-term soil P deficiencies. In this paper, we systematically reviewed relevant studies on “biochar and soil” or “biochar and soil P” published in the past decade (2013–2023). A…
