Specialist in soil improvement and plant growth.

At Den Ouden, we work to create a more livable environment for future generations every day. At Den Ouden GrowSolutions, we actively contribute to this by supporting growers worldwide in building fertile soils and strong, healthy plants. Together, we help ensure sufficient and nutritious food for the future.
A healthy soil contains sufficient organic matter and a rich diversity of micro-organisms. These organisms convert organic material into plant-available nutrients, enabling crops to grow naturally and resiliently. The presence of beneficial micro-organisms also reduces space for pathogens.
At Den Ouden GrowSolutions, we embrace resilient cultivation. Our portfolio includes a wide range of soil improvers, organic fertilisers, and biostimulants that support the interaction between plant and soil throughout all growth stages. This approach not only optimizes results during the growing season but also strengthens soil biology and enhances the long-term sustainability of agricultural systems.
In addition to our own GrowSolutions brand with soil improvers, organic fertilisers, and biostimulants, we offer other brands as well as complete private- or white-label solutions tailored to your needs. We collaborate with dealers, distributors, suppliers, and retailers worldwide.
We manage the entire supply chain: from raw material intake and quality control to packaging, labeling, palletizing, and global shipping. This allows us to maintain control over every step, ensuring consistent quality, traceability, and reliable delivery times.





At our production facility in Helmond, we process an impressive 100,000 tons of raw materials annually. We not only manufacture our own products but also process and package products for our partners.
Our modern packaging lines are running at full capacity. Per hour, we package approximately 30 tons of solid fertilisers into bags up to 25 kg, and 24 tons into big bags of 500 and 1,000 kg. Liquid fertilisers are efficiently filled at a rate of 360 one-liter bottles, 100 twenty-liter jerrycans, and eight large 1,000-liter IBC containers per hour.

At Den Ouden GrowSolutions, quality and sustainability are at the core of everything we do. Our company and products comply with strict quality standards and carry renowned certifications and approvals:
These certifications and approvals demonstrate that we deliver consistent, high-quality products and services, prioritize sustainability, and ensure our products are safe, effective, and environmentally friendly.
In 2023, Ferm O Feed and Plant Health Cure (PHC) joined forces to continue as Den Ouden GrowSolutions.

This merger allows us to offer an integrated portfolio of organic fertilisers and advanced soil biological solutions, enabling growers worldwide to cultivate more efficiently, sustainably, and profitably.
