NPK Gold®Twin High-K is a granulated NPK complex fertilizer with ISODUR® & CROTODUR® slow-release nitrogen, with an emphasis on potassium, magnesium and trace elements.
NPK GOLD®Twin High-K is a slow-release fertilizer with a very high potassium and magnesium content for an adapted nutrient supply of soil low in magnesium and potassium. Due to the high potassium and magnesium percentages, this formula can also be used on surfaces with a low nitrogen requirement. NPK GOLD®Twin High-K promotes healthy growth and generally makes the plants more resistant. The complete set of trace elements – iron, boron, copper, manganese and zinc – ensures optimal growth especially under these conditions.
