Optimal soil pH for vegetable garden
I just received my MSU soil test results, see results below. My question is, what is the optimal soil pH for things like Broccoli, Brussels sprouts, Cauliflower & Tomatoes? I'm trying to determine if I need to add sulfur or not this fall while I'm adding potash to raise my potassium. Both need to be tilled in before winter.
Phosphorus (P) 593 ppm; Potassium (K) 67 ppm; Magnesium (Mg) 281 ppm; Calcium (Ca) 2187 ppm; CEC 13.448 meq/100 g; Soil type MINERAL , Loamy sand; Soil pH 7.2; Lime index 0; Organic Matter 6.1 %

An ideal soil pH for a vegetable garden is 6.5 which is somewhat acidic. A soil pH of 7.2 is fine. If you needed to adjust the soil pH, that information will come with your recommendation.
If I had the code to your soil test recommendation, I could be more helpful. It is the number directly behind your name on the recommendation.
Thanks for your fast response.
Here is my soil sample number:
"Soil Test (#7LDC55) Report for Larry Hewitt - Garden (crop: Vegetable Garden)"
What is required on your soil test recommendation per 1000 square feet:
Nitrogen- 3-4 lb.
Potassium- 5.3 lb.
This translates into these amounts if you are using traditional fertilizers per 1000 sq. ft.:
N- 46-0-0 = 7 to 9 lb. per season, divided into 3 to 4 applications. In the spring, a week or two before planting use 1 to 2 applications of the 46-0-0 with the full amount of potassium and till into the soil at least 6 inches deep. In 6-8 weeks, use another part of the nitrogen. And in another 6-8 weeks use the last, if you were using 4 applications.
K- 0-0-60 = 9 lb. applied once in the spring (all of it) at the same time the partial nitrogen application is used.
Since all fertilizers are percentages and not 100%, this figures in the correct numbers.
You need 5% organic matter and that's fine at 6.1 %. Your soil pH is fine at 7.2
