Magnesium sulfate (or Epsom salt) is used to correct magnesium deficiency which can be common in the hydroponic production of vegetable crops. It is perfect for use as a part of a hydroponic nutrient solution because it is an inexpensive, highly soluble and naturally occurring.
- EPSO Top® is a quick acting magnesium and sulphur fertilizer for foliar application. The nutrients are fully water-soluble and are present in the sulphate form (MgSO4 × 7 H2O).
- EPSO Top® dissolves rapidly and without residue in water and is therefore perfectly suited to foliar application with a sprayer and also for fertigation through irrigation systems.
- EPSO Top® can be used as a supplement to soil application in particular if magnesium deficiency is observed and during periods of peak demand.
- EPSO Top® is approved according to regulation (EC) 834/2007 and (EC) 889/2008 for use in organic farming systems.
