Amino Acid Chelates
Express® MAGNESIUM
Premium magnesium amino acid chelate.
- pH 5.1
- SG 1.25
Premium magnesium amino acid chelate.
Key Benefits:
- Helps to correct and prevent magnesium deficiency.
- Suitable for foliar, in-furrow and fertigated applications.
- Small molecule, readily absorbed by the leaf via stomata and tissue.

Express® MAGNESIUM is used in a wide range of crops to correct and prevent magnesium deficiency. For horticultural, broadacre and viticulture production where magnesium deficiency may occur, Express® MAGNESIUM can be applied via foliar, in-furrow or fertigation.
Magnesium is a vital macro nutrient for chlorophyll production, which leads to increased photosynthesis and assists with the mobilisation and utilisation of iron and phosphorus. Magnesium is also important for seed formation and the formation of fats and oils, and is an essential activator for many plant enzymes.
The most effective way to apply Express® MAGNESIUM is via foliar application; however, it is suitable for in-furrow and fertigated applications as well as chelates minimise reactions in the soil solution, resulting in available nutrients for a longer period.
Magnesium deficiency:
Occurring in mostly sandy soils with low pH, magnesium deficiency in plants can also lead to grass tetany (magnesium deficiency in animals). Magnesium availability can also be reduced by cold conditions and applications of potassium. Crops particularly susceptible to magnesium deficiency include vines, fruit trees and vegetables.
Magnesium deficiency symptoms include:
- Symptoms appear first in old leaves (highly mobile).
- Weak plants.
- Curling of leaves upward along margins.
- Interveinal chlorosis through the middle of older leaves.
