Implication

Field experiment shows that straw return enhances nitrogen use efficiency in maize, suggesting significant benefits for soil fertility.

Key Points

  • Straw return significantly increases soil carbon and nitrogen fractions while improving maize yield and nitrogen use efficiency.
  • Under deep plowing with straw return, maize yield increased by 17.28%, while nitrogen use efficiency rose by 18.24%.
  • Three-year split-plot experiment evaluated varying nitrogen inputs and their impact on soil health and crop performance.
  • These findings support sustainable practices that can maintain soil quality while enhancing agricultural productivity.
