Soiltech - Model Optima Leaf-K -Potassium Foliar Fertiliser
Optima Leaf-K is a direct available potassium foliar fertiliser. Problems with potassium uptake are often related to the pH value of the soil. A high pH inhibits potassium uptake by the roots. And in drought conditions, potassium is not released into the soil, which prevents it from being absorbed. Foliar fertilisation using Optima Leaf-K offers a solution by supplying this important nutrient to the crop.
Optima Leaf-K contains a pH-neutral, very readily available form of potassium. Crops benefit from a supplement of potassium at cold soil temperatures, during drought conditions and at the end of the growing cycle when the crop is bulking tubers, bulbs, grains and fruits. Optima Leaf-K has been specially developed to supply (arable) crops with sufficient potassium through a foliar application in periods with a high potassium demand.
Optima Leaf Range
Optima Leaf-K is part of the Optima Leaf range, a line of organically complexed foliar fertilisers that are very efficiently absorbed by the crop.
- Contains a high concentration of directly available potassium.
- Boosts the yield and size of bulbs, tubers, grains and fruits.
- Improves quality and storage life (brix content, firmness).
- Increases the plant`s reserves (better hardiness).
- Better potassium absorption in dry conditions.
- Improves the drought resistance of the crop.
- Much more effective than adding potassium fertilisers via the soil.
- Very low chloride content.
