Summary
A total systems approach to dairy farm nutrient management is vital for the future. This holistic strategy optimizes nutrient flow and utilization across the entire farm system, improving sustainability and economics.
Area of Science:
- Agricultural Science
- Environmental Science
- Animal Science
Background:
- Traditional manure nutrient management focuses on production, collection, storage, and application.
- This limited scope overlooks crucial aspects of farm operations and environmental impact.
Purpose of the Study:
- To advocate for a total systems approach to dairy farm nutrient management.
- To highlight the necessity of optimizing nutrient flow and utilization throughout the entire farm system.
Main Methods:
- Literature review and synthesis of current practices.
- Conceptual framework development for a holistic approach.
Main Results:
- A total systems approach integrates human/animal health, odor/fly control, nutrient handling, feeding, crop management, manure processing, and economics.
- This approach addresses environmental regulation impacts and farm profitability.
Conclusions:
- A total systems approach is essential for the future of the dairy industry.
- Successful implementation requires multidisciplinary expertise including agronomists, dairy scientists, economists, engineers, microbiologists, soil scientists, veterinarians, and regulators.
