Providing magnesium for plants begins with annual applications of rich, organic compost. And many plants will suffer excess deposits of salt in the soil. Although magnesium (Mg) is one of the most important nutrients, involved in many enzyme activities and the structural stabilization of tissues, its importance as a macronutrient ion has been overlooked in recent decades by botanists and agriculturists, who did not regard Mg deficiency (MGD) in plants as a severe health problem.
