jprice, I'm with you for the most part. If you have a little more than a general knowledge of plants, and what it takes to grow them, you can read soil test results and make the appropriate application of a known fertilizer/amendment based on your soil type and other growing conditions, including the requirements of the particular crop you are growing. Many folks begin growing 'stuff' for various reasons, hops are a prime example. Most of the folks growing them are most likely brewers. That doesn't necessarily mean that they all have green thumbs. Fortunately, I think the organic option has probably saved many hop plants from being unwittingly 'toasted' due to the minimal amounts of the big three (N,P,K) that they generally contain. That's a good thing in my opinion.
Both organic and commercially produced products have their pluses and minuses and I do agree that many of the organic products probably tug at the heartstrings of many, but I've also seen 46-0-0 catch a lawn on fire once so I guess it's great to live in a country where you can hug a tree and watch the fire department at your neighbor's house while drinking a homebrew? Happy Belated Independence Day!!
