LUBOFOS ® 12

EU FERTILISING PRODUCT ● GRANULATED ● COMPLEX MACRONUTRIENT FERTILISER
PK (Ca, Mg, S) 12-20 (21-3-8)

  • for all types of field crops, particularly for soils low in potassium and magnesium
  • due to the high content of potassium relative to phosphorus, the product is recommended for root crops
  • due to the magnesium, which is necessary for the animals, it is recommended for growing cereals and grasslands
  • very good spreading properties
  • the micronutrients in the fertiliser improve the absorption of other nutrients

Usage

The highest efficiency is achieved by applying the fertiliser before sowing and mixing it with the soil at a depth of 10–15 cm during pre-sowing tillage. The fertiliser is suitable for all soils, regardless of their compactness and pH.

On grasslands, it is advisable to divide the dose into two parts and apply the first fertiliser dose in early spring and the second dose after harvesting the first cut or after the second grazing.
