Excessive Magnesium and Calcium - Vegetable and Flower Gardens #862327

Asked March 23, 2024, 3:36 PM EDT

Recently, we had our garden soil tested by the University of Delaware's labs, and the report came back showing excessive levels of Magnesium (243 index value) and Calcium (329 index value) where an index value of 100 was the cusp of being considered excessive. I assume this means these are much higher than normal levels of these nutrients, but I am not sure of anything. The report did have a few recommendations for soil amendments, which were mainly the application of Nitrogen fertilizers that were low in nutrients which we already had excessive quantities of. I was wondering if: A) The excessive nutrient contents listed above were generally a huge issue for vegetable and flower beds. B) If there is a way to directly amend the excessive nutrients. Thanks!

You can refer to our page on Understand your Soil Test Results.  Excessive nutrients of those elements are not an issue and you can't remove them anyways. They won't hinder any vegetable or flower growth. More so monitor the organic content and pH level. It will depend on what flowers you are trying to grow.
