I obtained a copy of "The Intelligent Gardener" and just started reading it. I think I'm in for some studyin'. It did raise a question though. I do some vegetable-growing in pots due to limited space. Normally, I use ProMix, some type of compost, perlite and an organic vegetable fertilizer. What's a cost effective way to get any minerals into the mix? I can see that for me, having several bags of mineral amendments for growing in pots might be a tad overwhelming. Is there a pre-made blend that would work well for that application?
