I have a book by Steve Solomon called, "The Intelligent Gardener- growing nutrient dense food". For years he had declining health. He was only eating food from his own organic garden in Oregon sin poor soil. He added a lot of organic matter and compost etc, but still his soil wasn't nutrient dense.
He explains how to read a soil test in detail, and by it, give your soil what it needs so that it is balanced. He gives a history of nutrition around the world and how what they are determined their health.
That was a lot of rambling. Hope it makes sense. The author started Territorial Seed Company.
