Amstel Agro Purple:

For better looking and stronger flowers and plants


Amstel Agro Purple gives your flowers and plants a deeper leaf colour, fuller flowers and a longer vase life. In addition, the crop is more resistant to diseases, pests and drought and therefore requires less crop protection agents.

Amstel Agro Purple is a mineral fertiliser based on easily absorbable orthosilicic acid. Amstel Agro Purple further contains the important micro-nutrients boron, zinc and molybdenum.

The effect of Amstel Agro Purple

Amstel Agro Purple ensures a larger and stronger root system of your crop and larger, firmer leaves. This allows the plant to absorb more micro-nutrients and convert more sunlight into energy. The crop thus becomes stronger, healthier and more productive. Consequently, stress factors such as diseases, insects and drought have less effect on the crop.
