Product description

NPK fertilizer (Ca-Mg-S) 5-6-10 (2-5-25)


  • Nitrogen (N),
  • Phosphorus (P),
  • Potassium (K)
  • Calcium (CaO)
  • Magnesium (Mg),
  • Sulfur (S),
  • Bor (B),
  • Copper (Cu),
  • Iron (Fe),
  • Manganese (Mn),
  • Molybdenum (Mo),
  • Zinc (Zn).



The fertilizer is intended for acidification of the soil, necessary for the proper growth of a large group of plants, e.g. conifers, blueberries, rhododendrons, azaleas, hydrangeas, heather plants, ferns, conifers and deciduous trees, hedges, currants, gooseberries, fruit trees, root vegetables , tomatoes, peppers, onions, cucurbits, brassica, strawberries and wild strawberries. The high sulfur content guarantees the effectiveness of the treatment. The fertilizer can also be used to eliminate iron chlorosis caused by iron deficiency or too high pH of the substrate, blocking the absorption of this element.

We use the fertilizer if the substrate is not acidic enough, i.e. it has:

pH above 4 - blueberries, rhododendrons, azaleas, heathers, heathers, ferns;

pH above 5 - conifers;

pH above 5.5 - hydrangeas;

pH above 6 - currants;

pH above 6.5 - strawberries and wild strawberries;

pH above 7 - root vegetables, tomatoes and peppers, hedges, ornamental deciduous trees and shrubs, fruit trees, gooseberries;

pH above 7.5 - celery, red beet, onion;

pH above 8 - pumpkin, cruciferous.


Recommended doses:

20-50 g of fertilizer (maximum annual dose) / 1m2 of soil in 3 divided doses in the case of fertilizing blueberries, rhododendrons, azaleas, heathers, heathers and ferns.

100-200 g of fertilizer (maximum annual dose) / 1m2 of soil in 2-3 divided doses (depending on the needs) when fertilizing other plants.

The fertilizer is applied every month - twice during intensive plant vegetation. Feeding should be discontinued in mid-August at the latest. After spreading the fertilizer, mix it with the substrate and water it abundantly.

The higher of the recommended doses is used for fertilizing soils poor in nutrients, the lower for fertile soils.
