Biochar impacts soil microbial community composition and nitrogen cycling in an acidic soil planted with rape
This was a pot trial, carried out in a greenhouse in Institute of Urban Environment with soil collected from a vegetable production ceter located in He county, Anhui Province, to study the effect of biochar on soil bacterial community composition and nitrogen cycling.There are four treatments in the pot trial of biochar amendment: addition of 5%(w/w) rice straw with rape (BP), addition of 5% (w/w) rice straw biochar without rape (B), untreated soil with rape (CP), untreated soil without rape (C).
