Three decades of green manure rotations sustain soil nitrogen supply by microbial functional restructuring under reduced mineral fertilization

Key Points

• Soil nitrogen supply benefits from three decades of green manure rotations, enhancing soil health.
• Analysis reveals significant microbial function restructuring and improved nitrogen supply with reduced mineral fertilization.
• Long-term assessment showed how green manure practices influence microbial roles in soil ecosystems over 30 years.
• Findings indicate important implications for sustainable agriculture practices, requiring further exploration in varied conditions.
