Experiment reveals biochar enhances nitrogen and phosphorus transformations in agricultural soil, suggesting improved microbial diversity.

Biochar amendment significantly enhances nitrogen and phosphorus transformations in agricultural soil, promoting nutrient availability.
The strongest effect on enzyme activities was observed with 1% biochar, which also improved microbial community diversity.
Observational analysis under rain-out shelters revealed varying impacts on microbial communities and nitrogen content with different biochar rates.
These findings indicate the potential of biochar as a soil amendment to address nutrient limitations in continuous cropping systems.

Li et al. (2025) studied this question.
