Effects of modified biochar and fertilizer application on soil nitrification and acidification in subtropical regions of China

Key Points

• Increased biochar application leads to reduced soil acidification and enhanced nitrification rates in subtropical regions.
• Soil samples showed a 20% increase in nitrification with biochar compared to traditional fertilizer alone.
• Analysis across subtropical regions demonstrates variations in soil chemistry due to biochar and fertilizer combinations.
• These findings underscore the importance of localized soil management practices for agricultural sustainability.
