Why choose NPK+S EKO?
NPK+S EKO combines nutrients with organic matter. It is an organic nitrogen fertilizer in granulated form, providing gradual and long-lasting plant nutrition. Thanks to the combination of fast- and slow-release forms of nitrogen, the product gives plants immediate growth support and even nutrition over several weeks.
Around 50% of the nitrogen is released within the first 14 days, while the remainder is released gradually, ensuring balanced fertilization and limiting nutrient losses. The product is intended for use in all types of crops.
The product can also be used on sites intended for stubble catch crops and cover crops. Properly selected cover crops support nutrient management, reduce nutrient losses and provide valuable organic matter.

Frequently asked questions
Practical answers about this product. Match rate and timing to the soil test, crop and current product label.
How does the extended nitrogen release mechanism in NPK+S EKO work?
NPK+S EKO combines ammonium and organic nitrogen. The product information states that around 50% of its nitrogen is released within the first 14 days and the remainder gradually over the following weeks; actual release varies with moisture, temperature, soil and biological activity.
What is the advantage of combining ammonium nitrogen and organic nitrogen?
The combination provides a readily available ammonium fraction alongside organic nitrogen that is released more gradually. NPK+S EKO lists 8% ammonium nitrogen and 4% organic nitrogen, supporting an early supply with continued nutrition rather than promising one identical response in every soil.
Can NPK+S EKO be applied using seed-placed applicators on precision drills?
Yes, the Bluebird application information lists NPK+S EKO for seed-placed applicators on precision drills. Use the equipment manufacturer's guidance and the current product label to set placement and rate for the crop.
Why is a chloride-free NPK fertilizer safer for sensitive crops and soil microflora?
A chloride-free formula avoids adding chloride from this fertilizer, which can be important for chloride-sensitive crops and management plans that limit chloride. NPK+S EKO also supplies organic matter and sulfur; 'safer' is not a guarantee for every crop or soil and the full program must be checked.
