Your CEC is good. (Cation Exchange Capacity). Anything over 12 is considered adequate--mine at my house is about 12, sandy infertile soil.
Sulfur coat, poly coat, Or MESA slow release is a good idea. 50 percent of the nitrogen as slow release is good, 70 percent is better. You can use a "bridge" product that combines slow release with organic fert if you like.
You should be in good shape if you are growing a grass suited to your climate, and a top variety that is disease resistant. Irrigation helpful. Tall fescue is your likely choice. More experienced people can help you there, but tall fescue can get brown patch disease if fertilized in hot weather.

I don't understand about the Calcium Magnesium ratio.
