Nova Mag-S


  • Advantages
  • Description
  • Directions for use
  • Agronomical advantages
  • Highly efficient source of Magnesium and Sulphur increasing chlorophyll activity and aminoacids synthesis
  • The product is Nitrogen free, which helps to adjust easily the fertigation program, matching the plants needs for Magnesium and Sulphur
  • Freely soluble and quickly dissolving.
  • Nova Mag-S is one of the magnesium-richest, fully-soluble and non-chloride fertilizers

Nova Mag-S is a high quality product, dedicated to be used in fertigation, completing the plants needs with its nutrients. It contains important nutrients for plant growth–Magnesium is the central part of the chlorophyll molecule, playing a key role in photosynthesis and Sulphur – an indispensable element in aminoacids synthesis.

Directions for use

Nova Mag-S can be applied by fertigation with practically all other soluble fertilizers, but when concentrated stock solutions are prepared, it should not be dissolved with fertilizers containing phosphates, e.g. Nova MAP, Nova PeaK, urea-phosphate or phosphoric acid, nor with calcium fertilizers (e.g. Nova Calcium). Its combination with potassium based fertilizers is limited too. Therefore, it should be dissolved in a separate dissolving tank, e.g. the trace elements.

Recommended dilution rate, for stock solutions = 15 kg / 100 liter water

Agronomical advantages

Nova Mag-S is an excellent source of magnesium for plants. Magnesium is the central atom in the chlorophyll molecule. Therefore, suboptimal availability of magnesium to the crop reduces the photosynthetic capacity of the plants, and hence, their agronomic performances will be impaired. Mg is also related to stimulation of P uptake. Nova Mag-S is optimal for hydroponics growth systems because it does not contain ammoniacal nitrogen. 

Nova Mag-S 0-0-0+16MgO+32SO3 is ICL SF’ Magnesium Sulphate fertilizer providing fully soluble and high purity nutrients, dissolving quickly in water.
