Soil test results

Asked May 24, 2013, 9:03 AM EDT

My soil test number is BDZ23A. It said there is 2067 ppm calcium in the soil. What is optimum, or necessary, to grow vegetables? Why was high nitrogen fertilizer recommeded? Thank you!

Michigan soils are calcium based so it is not unusual to get a soil test result high in calcium. High calcium values have no effect on vegetable crops. Nitrogen recommendation are based on the crop grown. High nitrogen products just mean that less of the fertilizer is required per square foot of planting area. Vegetables require 3-4 pounds of actual nitrogen per 1000/sq.ft per year. The amount distributed depends on the percent nitrogen concentration in the product used.
