KOH-modified hydrochar with nitrogen-fixing bacteria alleviates aluminum toxicity and mitigates acidification-driven nitrogen loss in soybean rhizosphere.
An innovative strategy combining KOH-modified hydrochar with nitrogen-fixing microbial aggregates (MGs) is developed and investigated its effects on rhizosphere acidification and nitrogen cycling in soybean, demonstrating that integrated material-microbe strategies offer a sustainable alternative to conventional liming...
