Recommended Use

Applied two to three times, 5-15 kg/ha of EPSO Bortop will cover peak magnesium and sulfur requirements and maintenance requirements for boron in crops requiring boron.
As a rule 2-3 x 5 kg/ha in 2.5-5% concentration (e.g. 5 kg/200 l water).
Spreading the amount over three applications increases efficiency.
Miscible with most crop protection products
First dissolve EPSO Bortop in 1/3 of the water, then add the other ingredients.
For blends, please follow the manufacturer's recommendations.
Test blends for full solubility in small quantities first.

The optimum application rate depends on the nutrient content of the soil, the cropping intensity and the yield expectation. The following recommendations are only guidelines.

Crop	Total quantity (kg/ha) (dosage)	Application period and recommendations
Rapeseed	10-15 (2-3 x 5-7.5 kg/ha in 200 L H₂O)	Fall to bloom; multiple administration
Sugar beet	10-20 (2-3 x 5-10 kg/ha in 200 L H₂O)	To close the row; with fungicide and insecticide treatments; multiple uses
Corn	5-15 (2 x 2.5-7.5 kg/ha in 200 L H₂O)	Until shortly before the row closes or up to a growth-height of 60 cm
