A healthy soil and improved crop yield—that’s every grower’s goal. With a reliable fertiliser of consistent, high quality, you can make the difference. 

At Den Ouden GrowSolutions, we choose a controlled production process. The result? A pellet of consistent quality. In this three-part series, we take you through the processing of the FertiSoil 4-3-3 pellet. In this second part we look at the basics: how do we select the raw materials?

Careful selection of raw materials upon arrival

The quality of FertiSoil 4-3-3 is largely determined by the composition and origin of its raw material—in this case, poultry manure. That’s why at Den Ouden GrowSolutions, we apply strict selection criteria. Every incoming shipment is inspected for composition, nitrogen, phosphate, potassium, and dry matter content. This ensures that only raw materials with an optimal balance of organic matter and nutrients are included in the process.

Additionally, we only work with suppliers who comply with national regulations, including legislation on antibiotic use. This not only contributes to the safety of our fertiliser but also enhances transparency across the entire supply chain.

Less transport, lower CO₂ emissions

In addition to quality, sustainability plays an increasingly important role in our production process. By sourcing raw materials as locally as possible, we reduce transport distances and minimize CO₂ emissions. This helps shrink our ecological footprint without increasing the cost of fertiliser production.

Animal welfare matters

Animal welfare is a key priority for us. We only collaborate with suppliers who handle their animals responsibly. Our partners meet strict standards and undergo annual inspections covering various aspects such as housing, stable systems, animal feed, medication use, animal health, and hygiene. This allows us to confidently state that FertiSoil 4-3-3 is not only beneficial for the soil but also for the supply chain behind it.

Moisture content, shelf life, and ease of use

FertiSoil 4-3-3 must not only be nutritious for the soil but also easy to use. That’s why we maintain a low moisture content—never exceeding 12%. Wetter organic products tend to ferment and clump together. By keeping moisture levels low, FertiSoil 4-3-3 remains long-lasting and easy to apply.

Beyond composition and shelf life, the physical form of FertiSoil 4-3-3 is also important. Our product consists of firm, uniform granules with minimal dust formation during transport, storage, and spreading. This ensures FertiSoil is simple and clean to use.

Smart packaging: quality all the way to the field

To maintain the quality of FertiSoil 4-3-3, we package the product in special polyethylene bags with micro-perforations. This allows for ventilation, preventing unwanted moisture buildup and preserving the product’s structure.

Why FertiSoil 4-3-3 adds value

Choosing FertiSoil 4-3-3 means investing in healthy soil, strong and resilient crops, and higher yields. Thanks to our strict selection criteria, sustainable supply chain, innovative packaging techniques, and 65% organic matter content, FertiSoil 4-3-3 is a reliable and responsible choice for the future of your farm.
