Usage

The highest efficiency is achieved by applying the fertiliser before sowing and mixing it with the soil at a depth of 10–20 cm.

The fertiliser does not contain ingredients that limit seed germination, which means that the plants can be sown 2–4 days after fertilising.

On grasslands, the fertiliser should be applied to the surface and spread once in early spring, using the dose intended for the entire growing season.

When used with vegetable crops, the fertiliser should be sown when the site is being prepared for cultivation.
