Usage

Powdered superphosphate is a standard 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. On grasslands, apply the fertiliser on the surface, without covering it with soil. Its nutrients will be gradually moved deeper by rainwater.
