| Sumario: | Recently, biochar has been widely used for versatile applications in agriculture and environment sectors as an efec‑ tive tool to minimise waste and to increase the efciency of circular economy. In the present work, we review the current knowledge about biochar role in N, P and K cycles. Ammonia volatilisation and N2O emission can be reduced by biochar addition. The content of available P can be improved by biochar through enhancement of solubilisation and reduction in P fxation on soil mineral, whilst high extractable K in biochar contributes to K cycle in soil. Liming efect and high CEC are important properties of biochars improving benefcial interactions with N, P and K soil cycle processes. The efectiveness of biochar on N, P and K cycles is associated with biochar properties which are mainly afected by feedstock type and pyrolysis condition |
