Complex fertilisers
Fertiliser type – B.1.1 NPK (Mg,S,B,Zn) 12-12-17 (+1,2+14+0,02+0,02)
Chlorine-free wholesome granulated complex fertiliser NPK (Mg,S,B,Zn) 12-12-17 (+1,2+14+0,02+0,02), intended for ornamental deciduous trees. All nutrients are contained in a granule, which ensures uniform distribution of the fertiliser as well as maximum absorption of the components by the plant. The fertiliser includes all the main nutrients required for ornamental deciduous trees both at the start of vegetation and in later phases of growth. It is enriched with boron (B) to ensure optimal growth of the trees plants as well as abundant, bright-coloured and long-lasting blossoming. The fertiliser does not contain chlorides, which means that it is suitable for all plants that are sensitive to chlorine.
