Overview

Analysis reveals cotton straw return enhances soil carbon in top and deep layers, suggesting improved soil health.

Key Points

  • Long-term cotton straw return significantly increased soil organic carbon (SOC) by up to 252.7% across soil profiles.
  • The study found SOC in topsoil increased initially but plateaued after 5-10 years, while deep soil showed significant improvements.
  • Assessment involved soil profiles up to 200 cm, utilizing control and varying durations of straw return treatments for analysis.
  • These findings highlight the need to explore deep soil carbon dynamics for better soil management practices.
