NP(+S+B+Zn)

 

 

Complex mineral fertilizers with trace elements (Boron and Zinc)

It is a concentrated, granular complex mineral fertilizer containing different mass share of nitrogen (N), common phosphates (P2O5), sulfate and elemental sulfur (S), and nutrient trace elements.

The production is suitable for fertilization of all flowers, garden and field crops.
