EU FERTILISING PRODUCT ● POWDERED ● STRAIGHT SOLID INORGANIC MACRONUTRIENT FERTILISER
P 17.5

  • for pre-sowing use for all types of crops
  • for all soils regardless of chemical composition
  • also for use on grasslands, where it performs better than granulated fertilisers
  • contains highly soluble forms of phosphorus
  • yield-forming effect thanks to the high sulphur content, activated throughout the plant vegetation period

Application

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.
