Calcium-enriched water-soluble NPK, high in potash

Idron Ca NPK 10-5-23 + OE

Idron Ca NPK 10-5-23 + TE is a potash-rich water-soluble NPK fertiliser enriched with calcium, for fertigation of all crops and for hydroponics, at the ripening-inducer stage. Its nitrogen is entirely nitrate and its trace elements are partly EDTA-chelated. Like the whole Idron range, it is low in chlorine (L.C.C.) and dissolves without sedimentation or clogging of emitters.

  • 10-5-23 formula enriched with calcium (8% CaO), a ripening inducer
  • Entirely nitrate nitrogen (10%), with 23% K₂O, 5% P₂O₅ and 2% MgO
  • EDTA-chelated trace elements (iron, manganese, zinc, copper) plus boron and molybdenum
  • Low chlorine content (L.C.C.)
  • Acidic solution: pH 3.31 at 1% and conductivity of 1020 µS/cm at 1‰
  • Suitable for hydroponics and fertigation, without sedimentation or clogging of emitters
