Magnesium is absorbed by the roots of the plant as magnesium ion (Mg2+). The magnesium ion plays an important role in the development chlorophyll, which gives the leaves of plants their healthy green colour. Also, magnesium is indispensable for the process in which amino acids are converted into proteins. With a good intake, the magnesium content in a plant can rise to 3%. Due to the natural origin, the nutrient content may vary.
