  • Downloads
  • Select MagPhos is high in magnesium 
  • Ideal for crops in the development stage with a high magnesium need 
  • Alternative for MKP and magnesium nitrate 
  • Close to a complex fertilizer 
  • Alternative source of magnesium 
  • Low in chloride and does not contain sulphates 
  • Very soluble and dissolves completely

Product benefits:

  • Magnesium plays an important role in the formation of chlorophyll and photosynthesis.  Magnesium crop deficiency can be induced by low concentrations of this nutrient in the soil or by elevated concentrations of competng cations like potassium or calcium.
  • Select MagPhos is fully soluble and can be diluted up to 400 gram / liter (at 20°C) without problems.  Select MagPhos is low in chloride and does not contain sulphates. In situations where an acidifying fertilizer is needed and in situations where high amounts of sulphates need to be avoided Select MagPhos is a great fertilizer to use.
  • Select MagPhos is nitrogen free which gives this product a benefit over the use of magnesium nitrate. It allows free and full control over which N-source to use to fulfill the nutrition program.
  • Select MagPhos can replace MKP (Mono Potassium Phosphate (0-52-34) and magnesium nitrate in a fertigation plan. 0,94 Select MagPhos + 0,42 potassium nitrate is +/- the same amount of nutrients compared to 1 MKP and 0,5 magnesium nitrate. In situations where magnesium nitrate is not available, Select MagPhos is a great alternative to give the crop the nutrients it needs.
  • Examples of crops that that need relevant amounts of magnesium in general are: cucumber, tomato, leek and banana.
