Get zinc where it’s needed quickly
Optima Leaf-Zn+ is a liquid foliar fertiliser based on zinc that has been 100% complexed with hepta gluconic acid (HGA).
Zinc is important for the production of auxins - plant hormones which govern leaf size. Leaf size determines the efficiency of photosynthesis so, in this context, zinc is one of the most important trace elements.
Benefits of Optima Leaf-Zn+
Delivers zinc in an organically complexed form.
Ensures efficient uptake and translocation of minerals.
Product approved for organic agriculture and horticulture in compliance with regulations EC 2018-848 & EC 2021-1165.

When to apply
Apply Optima Leaf‑Zn+ during leaf development, as soon as the crop is actively growing and there is a need for zinc. Specifically:
From the first (true) leaves right through to the crop’s active growth phase. Particularly useful in cases of (impending) zinc deficiency, for example on:
- Soils with a high pH;
- Light/sandy soils;
- Plots with high phosphate or calcium levels (which inhibit zinc uptake).
Functions of zinc
- An essential element for many plant processes.
- Important element for root growth.
- Plays an important role in the formation and activity of chlorophyll.
