Usage

Granulated superphosphate is a typical pre-sowing fertiliser for all types of crops and all types of soil. It should be mixed with the soil to a depth of 10–20 cm. It can be spread before pre-sowing and winter ploughing. On grasslands, apply the fertiliser on the surface, without covering it with soil. Its nutrients will be gradually moved deeper by rainwater.
