► 6M HCl acid hydrolysable forms of N in biochar were investigated. ► Influence of pyrolysis temperature on these forms also investigated. ► C and N cycling in biochar from different pyrolysis temperatures were studied. ► Modified C/N ratio for estimating net N mineralisation in biochar was proposed...
