excessive phosphorous, magnesium and calcium
Our vegetable garden in Annapolis has had no real production the past 2 summers. I had the soil tested by the Univ. of Delaware. The results showed that we have an excessive amount of phosphorous, magnesium and calcium. What do we do to mitigate these? When should it be done? Thanks
You did not mention the pH of your soil. Vegetables grow best in a pH of 6.2 - 6.8. If you are adding organic matter on a regular basis this can tend to raise the pH of the soil. The excessive nutrients are not a problem and you do not need to add more.
You can send us photos of your soil test results.
