Soiltech - Model Optima Leaf-Cu+ -Liquid Foliar Fertiliser
Optima Leaf-Cu+ is a liquid foliar fertiliser based on copper that has been 100% complexed with hepta gluconic acid (HGA). Copper strengthens cells and has a positive effect on sugar and starch production.
Optima Leaf+ Range
Optima Leaf-Cu+ is part of the Optima Leaf range, a line of foliar fertilisers that are efficiently absorbed by the crop. The `+` stands for the presence of supplement trace elements. These prevent one-sided fertilisation and demonstrably increase the effectiveness of the product.
Functions of copper
- Essential in the seed and fruit formation stage.
- Essential for chlorophyll formation and photosynthesis.
- Important for strong, flexible plant cells.
- Positive influence on the starch content, sugar content and flavour of fruit.
Possible causes of copper deficiency in plants
- Low copper levels in the soil.
- Soils with a high organic matter content fix copper which reduces its availability for the crops.
- Too much phosphate and nitrogen in the soil prevent the copper uptake in the crop.
- A high soil pH reduces the availability of copper.
- Delivers copper in an organically complexed form.
- Ensures efficient uptake and translocation of copper.
- Enrichi aux oligo-éléments.
