Say what? If you don't know where you are you have no way of knowing where to go. I wouldn't be caught dead without a soil and well water lab analysis to use a guide. Here's my go to lab which has similar results as the TX A&M lab. They're much faster and are certified.
https://www.wardlab.com/services/soil-analysis/They also offer soil health tests. Having said that I put in a few years of cover crops to build soil health, do a biological soil "plow", add humus, add N, etc. Takes years of successive plantings to do much good in my calcareous clay loam. Elbon rye and legumes of hairy vetch and Madrid yellow sweet clover, the latter popping up all the time in my RootBuilder pots and still growing wild out in the field after 15 years.
TX A&M nailed my soil nutrients. Since then I use mainly N as an additive and have bumper crops. I do the best of both worlds by using conventional and organic practices. There is value in both. Also found plenty of quackery to go around with the organic and natural "lifestyle" lemmngs over the years. You just have to be smart and not get carried away by what is a cult with many gardeners.
Nothing wrong with hydroponics either. Plant doesn't care where it gets its 13 essential elements so long as they come at the right time and in the right amounts. Dyna-Gro foods comes to mind which I've used for years.
Rogue hairy vetch flowering 15 years later.
Elbon rye. I cut it at 6' tall after it seeded.
Volunteer sweet clover (legume) in the greenhouse. How it gets there is beyond me.
