ARGUMENTATION ABOUT THE INNOVATIVE CHARACTER

Optima Leaf-K is the first and only potassium foliar fertiliser formulated with a plant compound that complexes the potassium. This unique formulation ensures that the potassium is absorbed very efficiently, is extremely gentle on the crop and has excellent miscibility in the tank mix. The result of Optima Leaf-K is higher drought tolerance, higher yields and better tuber quality.
Optima Leaf-K has been developed to provide crops with extra potassium to optimise production and quality during the summer period. Dry soil, spring leaching, or high tuber setting can upset the balance between crop potassium supply and demand. In addition, during the ripening phase, crops take up potassium less easily via the roots, when the crop's need is at its maximum. The result is lagging production and quality and increased sensitivity to drought and heat.


ADDED VALUE FOR THE USER (IN COMMERCIAL TERMS, USER-FRIENDLINESS ...)

Optima Leaf-K is proven effective in several crops. Several trials in potato at PCA, Rusthoeve and SPNA show an average increased yield of more than 8%. Optima Leaf-K is a liquid product, gentle on the crop and does not react with other components in the tank mix.


ADDED VALUE FOR THE FURTHER SUSTAINABILITY AND PROFESSIONALIZATION OF THE POTATO SECTOR

Climate change and decreasing inputs of fertilisers and crop protection products require a more robust cultivation system. By applying 3x 5L Optima Leaf-K, the over-fertilisation of granular potash can be replaced. This saves about 50 kg of pure potassium. For a resilient crop, it is also important that nutrient levels in the leaves are sufficiently high and in the right ratio. Potassium deficiency not only results in reduced yield and quality, but also makes the crop more susceptible to abiotic stress, resulting in reduced resilience.


IS THE INNOVATION A RESULT OF YOUR OWN (INTERNAL) DEVELOPMENT?

yes
