Recommended Use

25 kg/ha of epsoMICROTOP covers peak magnesium and sulfur needs as well as maintenance needs for boron and manganese when applied once or twice.
As a rule, apply 25 kg/ha at 5% concentration (5 kg/100 l of water).
Apply in several partial applications when water volumes are low.
In the event of severe deficiency and/or visible deficiency symptoms, apply up to 50 kg/ha, divided into two to four partial applications.
First dissolve epsoMICROTOP 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 a small amount 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.

For boron-sensitive crops, such as cereals, use only after knowing the boron content of the soil or plants.

Crop	Total quantity (kg/ha) (dosage)	Application period and recommendations
Rapeseed	25-50 (3-4 x 5-15 kg/ha in 200 l H₂O)	Fall to bloom; multiple administration

Suitability for Organic Farming

K+S's plant nutrients are extracted from natural underground deposits of crude salt. They were formed many millions of years ago when primeval seas evaporated. Today, the salt layers are covered by several hundred meters of rock. They are mined by K+S and processed above ground into our products.

Due to the natural raw materials and the minimal processing effort required for further processing, many K+S products are ideally suited for organic farming and are approved for organic farming in accordance with EU Regulation 2018/848 and EU Regulation 2021/1165.
