Efficient Nutrient Use of Slurry – a Cost Saving Approach

Why It Matters

By matching slurry nutrients to soil test data with GPS‑guided equipment, farms cut fertilizer and fuel expenses while boosting yields, delivering immediate financial and sustainability benefits.

Key Takeaways

• Soil testing guides precise slurry placement, cutting fertilizer waste.
• GPS‑guided auto‑steer and flow meters deliver exact application rates.
• 3,000 gallons per acre applied consistently improves nutrient distribution.
• Managing slurry viscosity prevents line clogs and equipment downtime.
• Targeted P and K application reduces diesel use and operational costs.

Summary

Efficient nutrient use of slurry is the focus, highlighting how rising fertilizer and diesel prices drive farms to adopt precision technologies. Over the past four years, more than 200,000 soil samples have been analyzed by Chagas, allowing nutrients—especially phosphorus and potassium—to be matched to field needs.

The video showcases contractor Jonathan Catter demonstrating a tractor equipped with a flow meter and GPS auto‑steer. The system applies slurry at a calibrated 3,000 gallons per acre, eliminating guesswork and ensuring uniform distribution. Managing slurry viscosity and water content prevents line clogs and equipment downtime.

Catter notes that thin slurry avoids silage contamination and that collected dirty water is routed underground for rapid drainage. He emphasizes that precise application, guided by soil test results, maximizes nutrient efficiency while reducing fuel consumption.

For growers, adopting these tools translates into lower input costs, higher crop yields, and a smaller environmental footprint, making precision slurry management a strategic advantage.

Original Description

As fertiliser prices increase significantly, it is more important than ever that farmers get the best value from their organic manures on farm. In this video, Climate Advisor with the Signpost Advisory Programme Gary Fisher joins local contractor Jonathan Catterson to discuss how proper slurry management on farms can improve nutrient use efficiency and save costs for farmers.
