I'm not anti-artificial fertilizer, per se, but I do prefer to use my own organic chicken run compost. Like you, I have tried to live by the motto of feeding the soil and the soil will feed the plants. I think most artificial fertilizers feed the plants and do not help the soil at all.
Also, over the years, I have gone to less and less tilling as I have heard that it disrupts all the good living organisms in the soil that we want to encourage. Having said that, the first few years I attempted gardening here at the lake, I was tilling in as much organic material I could throw on the sandy soil garden. I think you have to have a good healthy base soil before the no till method makes sense.
