Soiltech - Model Optima Leaf-KS -Potassium / Sulphur Foliar Fertiliser
Optima Leaf-KS is an easy-to-use potassium / sulphur foliar fertiliser specially formulated for immediate and efficient uptake. It contains different forms of potassium, sulphur and a biodegradable effluent to make uptake even more efficient. A foliar fertilisation with Optima Leaf-KS supports crucial processes in the plant, giving better yields with better quality.
Potassium intake is very important to keep crops vital during dry and hot periods. In addition, potassium plays an important role in filling the grains, bulbs, tubers or fruits. Sulphur plays an important role in the formation of proteins and enzymes in the plant. Due to the increasingly clean air, there is less and less freely absorbable sulphur in the soil.
Optima Leaf-KS contains not only various forms of very easily absorbable potassium (K) but also a high level of directly absorbable sulphur (S). The biodegradable wetting agent ensures even better distribution of the droplet on the leaf and therefore even better uptake. Despite potassium and sulphur nutrients given via the soil, a large proportion of leaf analyses show potassium and/or sulphur deficiency during tuber/bulb/fruit growth. Optima Leaf-KS has been specially developed to provide fruits, vegetables and field crops with sufficient potassium and sulphur via a foliar application.
- More effective than fertilisation through the soil.
- Better uptake in more extreme (weather) conditions.
- Contains readily available potassium and sulphur in a high concentration.
- Is quickly and easily absorbed by the crop.
- Improves yield and fruit size (grading).
- Improves quality and preservation (brix content, firmness).
- In perennial crops, increases plant reserves (better winter hardiness).
- Improves crop drought resistance.
- Promotes protein formation. (Sulphur is essential for the plant to form important proteins).
- Low in chlorine.
