Litter decay rate response to nitrogen addition and regulatory factors for Chinese grasslands

Key Points

• Litter decay rate significantly increases with nitrogen addition, enhancing nutrient cycling.
• Key evidence shows a 30% increase in decay rates after nitrogen application in tested plots.
• The approach employed involves observational analysis of grassland litter decay under varying nitrogen conditions.
• Supports the role of nitrogen as a crucial factor in regulating litter decomposition processes.
