Utilizing Corn Stover Resources for Sustainable Agriculture

Strategic Insights

— 1 min read

Researchers at Zhengzhou University have published a groundbreaking study on the comprehensive evaluation of agricultural residues corn stover silage. This innovative research aims to optimize the resource utilization of corn stover, a typical agricultural waste, to promote ecological and economic benefits. The study, funded by the Qinghai Province Key R&D And Transformation Plan of China and the Independent Selection of Basic Research Business Expenses, Qinghai Academy of Animal Science And Veterinary Medicine, suggests that the addition of specific microorganisms and plant materials to corn stover can enhance its fermentation quality and aerobic stability.

Key Takeaways:

  • The researchers investigated the impact of additives on the fermentation quality and aerobic stability of corn stover silage (CSS) and found that the separate addition of * *Artemisia argyi* * (AA) or * *Lentilactobacillus* * (L.) * *buchneri* * (LB) in CS effectively improved the silage quality and aerobic stability.
  • The study revealed that LB exhibited the lowest pH value of 3.72 at 90 d of fermentation, while the NH [ [3] ] -N content was 0.07 g/kg DM during the anaerobic fermentation stage and 0.19 g/kg DM during the aerobic exposure stage.
  • The addition of AA upregulated carbohydrate metabolism and lipid metabolism during the ensiling process, and their relative abundances remained high during aerobic exposure.
  • Utilizing CS resources as feed to provide fiber and nutrients for ruminants can reduce the pressure on forage demand and meet the development needs of 'grain-saving' animal husbandry.
  • This research is conducive to solving the contradictions of 'human-animal competition for food' and 'human animal competition for land'.

Statistics:

  • The pH value of 3.72 at 90 d of fermentation was observed when LB was added to the CS.
  • The NH [ [3] ] -N content during the anaerobic fermentation stage was 0.07 g/kg DM, while it was 0.19 g/kg DM during the aerobic exposure stage.
  • The study showed that the addition of AA upregulated carbohydrate metabolism and lipid metabolism during the ensiling process.
