I'm new to gardening but have been reading "The Intelligent Gardener by Steve Solomon and it covers what you're talking about here. He has his own target levels that are designed for nutrient density, but the book breaks down exactly what to add based on a Logan's lab soil test. There's worksheets for different types of soil. "Acid-soil worksheet" "calcareous soil worksheet", etc. It's largely about balancing the nutrients in the soil. He only uses organic amendments though. Here's a really great website that has tons of info.

Good luck with your garden.
