Usage

The highest efficiency is achieved with pre-sowing fertilisation. After application, the fertiliser should be mixed with the soil at a depth of 10–20 cm. The fertiliser can also be used before pre-sowing ploughing. When growing sugar beets, avoid using large doses of the fertiliser immediately before sowing. On sites intended for beets, any adjustments to the soil content that require a large dose of the nutrient should be made in autumn. On plantations of winter crops, the fertiliser can be applied as a top dressing before the start of spring plant growth.

On permanent grasslands, fertilisation is best done in early spring. If it is necessary to introduce a large amount of potassium into the soil, a part of the dose should be applied after harvesting the first crop or after grazing.
