Chelated multi-trace-element microgranule

Atrium QS

Atrium QS is a micronutrient cocktail balanced according to plant uptake parameters, in a solid formulation to correct and prevent multiple deficiencies. It comes as a microgranule that dissolves rapidly in water. The combination of EDTA, EDDHSA and HGA chelates or complexes 100% of the metals in the blend.

Six trace elements: Fe 7.0%, Mn 3.3%, Zn 0.6%, Cu 0.3%, B 0.7% and Mo 0.1%
Rapidly dissolving microgranule in water
Stability and solubility guaranteed by the EDTA, EDDHSA and HGA combination, over a pH range of 2 to 12
Fertigation: 1–3 kg/ha every two weeks
Suitable for organic farming (Reg. (EU) 2018/848)
No incompatibility detected with pesticides
