Use of Citrate of Magnesia

Asked April 18, 2014, 5:55 PM EDT

I have seen trace minerals that are important to plants including magnesium. Have couple of bottles of Citrate of Magnesia that was obtained for medical use. Was wondering if it would be helpful to plants and if so which might be particularly helped by use of magnesium.

Don't let the similarity in their names fool you. Despite sharing every letter but one, magnesium citrate and magnesium nitrate are drastically different substances. While magnesium citrate is a common type of magnesium supplement often used as a laxative, magnesium nitrate is a toxic substance with agricultural, commercial and industrial uses. . If you plan to use magnesium nitrate, observe all handling and storage precautions.I hope this helps answer your question and thank you for using Ask an Expert.
