Soil application:

The general dose for single application varies between 3 – 10 kg/ha/application. Timing and dosage depends on the crop involved.
For continuous fertigation, the recommended concentration in feed solutions varies from
0.3 to 1,5 g/l (0.03 to 0.15 %). The standard recommendation for most cropping conditions is 1 g/l of water.


Foliar application:

Apply 2 – 5 kg/ha/application with a maximum concentration of 0,5% (5 grams per liter).
Always use in sufficient water volume to guarantee full coverage of the foliage.


Crop specific recommendations can be given upon request and according to specific soil, crop and climate conditions.
