Our sister company Euroliquids, conveniently located in the port of Rotterdam, is the largest liquid fertilizer factory in Northern Europe. This is where we produce our high quality liquid fertilizers and work on developing innovative new recipes.

Producing high quality

The factory is completely automated and has a well-equipped laboratory. Combined with the experienced staff it enables us to formulate and produce high quality and innovative products, with a long shelf life. The production facility is certified (ISO 9001:2015) and its staff has over 30 years of experience in producing liquid fertilizers.

From the start, Euroliquids is a producer of liquids for the high-tech Dutch hydroponic sector. This demanding market requires highly pure products with limited detrimental elements. We take the benefit of this experience to develop new formulas for foliar application and fertigation in open field. At Van Iperen, we are very active in these growing markets since more than 10 years.

Being located in the port of Rotterdam, the plant is ideally situated to ship our products all over the world.

Innovative liquid fertilizers

Woman working in the lab at Euroliquids

Our laboratory at Euroliquids supports us in the formulation of innovative products. Our chemists are experienced to create new recipes based upon the needs of the market.

Special attention is paid to the stability over time. Therefore all our new liquid products are confronted to a challenge test, analyzing the stability of the formulas up to a temperature of 50°C. By doing so, a stable product within a large temperature window can be guaranteed. Different parameters are monitored like crystallization temperature, pH, gasification and biological activity.

The focus on shelf life and therewith the challenge test is especially important when combing mineral fertilizers with organic biostimulants, like in our FoliaStim® and Iperen IPE® range.

Customized packaging

In addition to delivering high quality products, we also care about the packaging. Our liquid products can be packed in an extended range of cans and bottles varying from 1 liter up to 1.000 liters. Special attention is given to the selection of the cans as well as the full color labels. We do not only offer a nice label design, our Document Management team also adapts it to the local restrictions. This enables you to differentiate on the shelves.

Our FoliaStim® range

FoliaStim® Ultimate Liquid

Van Iperen FoliaStim® Ultimate Liquid is a pure and highly concentrated liquid NPK fertilizer, formulated with 15% seaweed, mineral nutrients and EDTA chelates. Our product is a stable solution and is recommended during phenological stages with high stress levels and nutrition needs, such as intensive vegetative growth, and high production phases. The synergy between our seaweed extract and the balanced NPK and chelated micronutrients content in our formula provides adequate readily available nutrients at critical stages, improving the plant performance and providing the support needed to optimize yields. The presence of high quality seaweed supports the uptake and the transportation of nutrients and increases resistance against abiotic stress.

Nitrofol Liquid 18 - 0 - 0 + 6(SO₃) + SW

Van Iperen Nitrofol Liquid | 18 - 0 - 0 + 6(SO₃) + SW is a highly concentrated Nitrogen formula with the biostimulant effect of the Ascophyllum nodosum extract. This solution has been specifically developed to increase protein quantity and quality in cereals. Nitrogen and Sulphur are key nourishing elements for cereals and their NUE is strongly influenced by their relative ratio. The suitable Nitrogen-Sulphur ratio of Nitrofol Liquid | 18 - 0 - 0 + 6(SO₃) + SW boosts the protein formation in particular when applied in the last part of the growing season. The Ascophyllum nodosum extract acts as a biostimulant reducing and preventing stress effects on the crop and at the same time acts as a wetting agent ensuring a longer and more efficient nutrient uptake. Nitrofol Liquid | 18 - 0 - 0 + 6(SO₃) + SW can be applied via foliar application with no risk of leaf burning for any application preferably at the end of the day or eventually very early in the morning.
