Highly effective, liquid complex fertiliser for root and leaf uptake in agriculture and horticulture

Intelligent fertiliser application system adapted to actual needs

FLEX Fertilizer System is a nutrient management system comprising of three series of liquid fertiliser: FLEX Basis for root uptake, FLEX Foliar for leaf uptake, and FLEX Micro for micronutrients.

The system is based on a number of flexible formulas that can be easily adjusted and adapted to the individual farmer’s – needs, so fertiliser is always applied optimally, both in terms of growth and cost. We call this: intelligent fertiliser application.

Our vision for the future is to move as much fertilising over to foliar formulas as possible, as this provides the greatest effect with reduced environmental and climate impact. We can then futureproof the fertilising process to avoid – nutrients leaching into the groundwater and adapt farming to a future where the environment and climate play an increasing role, politically.

We also have solutions that make it possible to recycle e.g. phosphorus from wastewater, – so the nutrient cycle remains intact and future-oriented.

In order to adapt to an increasingly unpredictable climate, we have developed our foliar fertiliser so it works in droughts and remains in liquid form for optimal effectiveness under all conditions. This also provides the chance to fertilise later than would normally be possible and optimise yields right up until harvesting.

Combining our products is easy through FLEXandMATCH. We have made it possible to mix many of our products with each other as well as a large number of pesticides, so you can save trips to the field and thereby optimise the number of applications.

If you choose to produce your own FLEX Fertilizer System fertilisers using a FLEXonFARM unit, you have even more independence and can purchase raw materials wherever they are cheapest, but if you just want to get started quickly, our producers can supply premixed products as FLEXtoGO in drums, pallet tanks or in bulk.
