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.
