A crop draws each nutrient in a different amount, at a different moment in its season. Three grades, built to that shape rather than to what the market already buys.
One per segment. Each is a compound built around the stage where the crop's demand actually peaks — not a general-purpose bag asked to cover everything.
Not nitrogen. Every crop where whole-season uptake has been measured removes more potash than nitrogen, and markedly less phosphate than either — the same order, without exception across the crops reviewed. These grades are weighted to that order.
Demand is not flat across a season. It climbs into the reproductive and filling stages — long after a single dressing at sowing has been applied and taken up. That is why each grade is designed around two applications, positioned by growth stage.
The physical requirement differs by segment before any ratio is chosen.
Granular, soil-applied, spread with existing equipment. Sulphur and zinc carried in the prill.
Rules out anything needing fertigation the field does not haveChloride-free. A sulphate base rather than a chloride one, on agronomic and salinity grounds alike.
Rules out muriate-based potash where chloride sensitivity is realFully water-soluble, clean through drip and fertigation lines at injection strength.
Rules out granular product, and anything that drops out of solutionAll three grades are in development. Initial trials are running at VAN's own R&D centre, and no trial result or yield figure is reported on this page.
Chemistry matched to the crop and its stage, rather than to the shape of the bag on the shelf. If you grow one of these crops, VAN already publishes a dose and a growth stage for 28 of them today. If you are a brand, distributor or manufacturer, the conversation starts with a dossier.
