Optima Leaf-NPK vital

Back to product overview

Optima Leaf-NPK vital is a liquid NPK leaf fertiliser (6-20-5), high in phosphorus content and enriched with amino acids. The nutrients in Optima Leaf-NPK vital stimulate crop growth, therewith increasing yield and quality.

Optima Leaf-NPK vital contains high levels of phosphate as well as nitrogen, potassium and added amino acids. These components support root growth and improve crop development. Application of Optima Leaf-NPK vital enables the crop to make better use of the fertilisers supplied to the soil, especially under less favourable soil and climate conditions.

Optima Leaf-NPK vital ensures a good start for the crop. It also provides and retains crop colour. It helps to keep crops vital if fertilisation via the roots is not optimal, for example in case of root stress and wet or cold conditions.
