Liquid Magnesium Sulphate

Whilst few Australian soils in the broadacre cropping regions are deficient, Magnesium categorised as a secondary element is still just as important as the other sixteen essential plant nutrients. Crops require Magnesium to capture the suns energy for growth and production through photosynthesis. It is an essential component of the chlorophyll molecule, the green pigment where the photosynthesis occurs.

Magnesium availability decreases at low pH levels, and at high pH levels excessive Calcium may have a dominant influence on Mg uptake by plants.
