100 percent silt is very unusual. I would go with Sandy loam. Knowing all of the central control system and smart controllers I don’t know of any that has a setting for just silt. Where was your soil test done? I’d feel better if cooperative extension service were doing the test. Besides giving you the soil description they will also give pH and recommendations on lime application if the pH is too acidic. I work with a person who has her masters in soil science and will see what she says about a 100 percent silt soil. I am skeptical.
