Farmers have traditionally used manure as a fertilizer and soil amendment. While it offers numerous benefits, improper application can lead to nutrient runoff and environmental pollution.
Low-disturbance manure application (LDMA) provides a sustainable solution that protects water quality and improves soil health.
LDMA involves injecting manure into the soil using specialized equipment. This method mimics the benefits of tillage without its negative effects, reducing odor and minimizing runoff.
A recent demonstration at a Wisconsin dairy farm showcased the effectiveness of LDMA. The farmers used a modified vertical-till machine with a hose line to distribute liquid manure. The machine creates shallow slots in the soil, allowing for better absorption and reducing the risk of runoff.
LDMA offers several advantages:
- Improved nutrient absorption: Manure is injected directly into the soil, promoting efficient nutrient uptake.
- Reduced nutrient runoff: Minimizes the risk of pollution from surface runoff.
- Enhanced cover crop establishment: Creates favorable conditions for cover crop growth.
- Reduced odor: Reduces unpleasant odors associated with traditional manure spreading.
- Improved soil health: Promotes better soil structure and microbial activity.
By adopting LDMA, farmers can contribute to a more sustainable agricultural system while protecting the environment. This practice is gaining popularity as it aligns with the growing emphasis on sustainable farming practices and water quality conservation.
