Importance of Magnesium in plant growth
- Magnesium is an essential plant nutrient. It is an important
constituent of chlorophyll, and has an essential role in the translocation
of starch within the plant.
- Magnesium has a crucial role in protein synthesis and enzyme
systems, and is closely associated with copper and zinc.
Deficiency symptoms include:
- Yellowing within the veins and outer leaves, more commonly
in older growth.
- Leaves may be abnormally thin and brittle, severely deficient
plants tend to take on a purplish colour on leaf tips and margins.
- Trees with magnesium deficiency are more prone to pest and disease
infection, and in some cases drop their leaves prematurely.
Benefits of using Magnesium Sulphate
• Magnesium Sulphate is a cost effective method of preventing
and correcting magnesium deficiency in a variety of plants.
• Magnesium Sulphate is a highly soluble crystal that can
be used in hydroponics fertigation and foliar spraying.
