原文摘要 | This chapter describes the research performed in New Zealand on (i) pyrolysis engineering (feedstocks, scale of pyrolysis, reaction design), (ii) biochar characterization (carbon sequestration value, fertilizer value), (iii) biochar carbon stability, (iv) biochar influence on N dynamics in soil–plant systems, (v) other uses of biochar in New Zealand (e.g., soilless agriculture and remediation of sheep dip sites), and (vi) environmental impact and barriers to adoption. We propose some priority research areas, which will mainly involve specific case studies where biochar may confer some advantages (e.g., vineyards and orchards) and some general science questions that should help attain a better understanding of the impact of biochar on specific soil processes. |
