    • How biochar works, and when it doesn't: A review of mechanisms controlling soil and plant responses to biochar 

      Joseph, Stephen; Cowie, Annette L.; Van Zwieten, Lukas; Bolan, Nanthi; Budai, Alice Erzebet; Buss, Wolfram; Cayuela, Maria Luz; Graber, Ellen R.; Ippolito, James A.; Kuzyakov, Yakov; Luo, Yu; Ok, Yong Sik; Palansooriya, Kumuduni N.; Shepherd, Jessica; Stephens, Scott; Weng, Zhe (Han); Lehmann, Johannes (Peer reviewed; Journal article, 2021-07-27)
      We synthesized 20 years of research to explain the interrelated processes that determine soil and plant responses to biochar. The properties of biochar and its effects within agricultural ecosystems largely depend on ...
