I had the soil tested last year by the MSU Extension for my 48 square foot vegetable garden. I added the items that were low (nitrogen-phosphorus-potassium- 3-0-3). Then I planted tomatoes, cucumbers, lettuce, basil & peppers. Is there any need to have the soil tested again this year? Is nitrogen needed every year? Thank you.

You will not need to test your soil every year. We recommend re-testing in three years.
Nitrogen should be applied annually in the amount recommended in the report.
