- Intervention effect Fertilization increased neutral amino acids by an average of 830 μg/kg.
- Intervention effect Fertilization increased basic amino acids by 300 μg/kg.
- Intervention effect Fertilization increased acidic amino acids by 80 μg/kg.
- Intervention effect Mixed fertilizer increased soil microbial C by 79.88%～97.14% relative to chemical fertilizer alone.
- Intervention effect Mixed fertilizer increased soil microbial N by 29.73%～74.96% relative to chemical fertilizer alone.
