What Is Soil Mate Opti-Mag?

Opti-Mag is a premium source of liquid Magnesium for soil and plant nutrition which contains forms of Magnesium that deliver the applied nutrient to the plant in a form that is more compatible to the plant's biological processes.

Opti-Mag contains added carbon chelators and advanced fulvic acid extracts, which individually are very useful plant stimulants or microorganism food sources or both. Here again,  as  with  most  of  our  liquid  products, combining significant amounts of these compounds together creates a SYNERGY - where all the components together give a greater result than all of them  would  give  if  applied individually.

The use of Opti-Mag assists plants with formation of the chlorophyll molecule, regulation of Nitrogen within the plant and sucrose transport, energy metabolism as well as numerous biological processes.

 Opti-Mag is exceptionally effective applied via fertigation.
