Optima Leaf NPK+ is a liquid NPK leaf fertiliser (8-17-9) enriched with trace elements, amino acids, fulvic acids and seaweed extract. The nutrients in Optima Leaf NPK+ improve growth and reduce susceptibility to abiotic stress.

Optima Leaf NPK+ includes high levels of phosphate and seaweed extracts, two components that act synergistically on root growth and activity. Application of Optima Leaf NPK+ enables the crop to make better use of the fertilisers supplied to the soil, even under less favourable soil and climate conditions.

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