Biochar amendment alters the partitioning of nitrate reduction by significantly enhancing DNRA in a paddy field

2022

Highlights Biochar amendment significantly increased DNRA rate in the paddy soil. Increased DNRA rate was due to enhanced C availability and enriched DNRA bacteria. Biochar amendment shifted more nitrate partitioning toward DNRA process. Potential of straw-derived biochar in alleviating N loss was superior to straw itself.
