Bacterial Mobilization of Nutrients From Biochar-Amended Soils.

摘要: Soil amendments with biochar to improve soil fertility and increase carbon stocks have received some high-level attention. Physical chemical analyses of amended soils biochars from various feedstocks are reported, alongside evaluations plant growth promotion capabilities. Fewer studies investigated the microbiota their potential cycling mobilization nutrients in biochar-amended soils. This review is discussing latest findings bacterial contribution mobilizing nitrogen, phosphorus, sulfur contributions promotion. Depending on feedstock, pyrolysis, type, cover, changes community structure were observed for a majority using amplicon sequencing or genetic fingerprinting methods. Prokaryotic nitrification largely depends availability ammonium can vary considerably under amendment. However, denitrification di-nitrogen particular, nitrous oxide reductase activity commonly enhanced, resulting reduced emissions. Likewise, fixation appears be regularly enhanced. A paucity suggests that phosphorus enhanced as well. most only tested extracellular sulfatase phosphatase activity. Further research needed reveal details nutrient capabilities this particular case sulfur.
