Soil Calcium to Magnesium Ratios—Should You Be Concerned

Exchangeable calcium and magnesium are attracted to negatively charged sites on clay and organic matter in soil where they are not easily leached from the soil but are available to plants. Currently, almost all soil testing laboratories in the United States use the test for exchangeable calcium and magnesium.

Nov 01, 2016 Calcium and magnesium are two of the three secondary nutrients required by plants, the third being sulfur. They are secondary in as far as quantities required for growth, not importance of function. Simply put, calcium and magnesium are necessary for plant growth and development and are easy to fix in the case of a deficiency.

Magnesium in plants and soil

Magnesium is in a form most easily uptaken by plants when the soil pH is between 7.5 and 9 but provided the pH is between 6.5 and 9.5 most plants should be able to uptake adequate amounts (as long as the soil contains sufficient magnesium). Plants that require a pH outside this range (such as azaleas and blueberries) may require more magnesium
