Very nice introduction to companion planting. I teach the 5 components of companion planting; spacial, botanical, biological, nutrient cycling, succession and rotation. I have more info on my blog; ;frankholzman.blogspot.com and in my book, Radical Regenerative Gardening and Farming.

One of the most important things I did was apply dolomite and limestone to my soils, I already do the square foot garden in raised beds full of rabbit compost, but plants lose minerals through successive harvests, and calcium should be 68% of the soil minerals, and magnesium should be 12-20% of soil minerals for optimal growth, Dolomite is Ca/Mg and limestone is Ca/60 minerals. Joel Wallach advocates spreading wood ashes on the garden but forgot to mention, to do this AFTER you leach out the lye (which you can then use to make liquid soap>) I learned this the hard way as I killed a tree. But wood ashes are likely to have more of the minerals we so need. But in his books, Rare Earths Forbidden Cures, and Epigenetics, and Immortality, he has a huge listing of the 60 minerals, what research has shown some of them to do, and what rocks had the best amounts, ---limestone was one of the top rocks. Now it wouldn't be too helpful for us, but the microbes in a good compost help the plants to uptake these minerals in their roots, and their availability allow the plants to make a better quality protein, more vitamins, the minerals in the crop of course and help them make hormones that resist insects and the ability to resist disease.
