I've heard about the ability to see what soil needs from the weeds that come from it, but only in brief segments and paragraphs. I've never come across anything in-depth about it so I'm starting to look for some more info.
Most people on this forum have probably heard something along these lines. The idea is a "weed" will pull up nutrients from below the soil level and bring it to the top so that it can feed the soil. There are other components of this, but that's one of the basic things I've heard.
Does anyone know of any books that are useful for this kind of identifying?

Aside from being nutrient accumulators, it's really useful knowing what weeds like what conditions. For example, dock and ranunculus thrive in acidic, waterlogged, compacted, anaerobic soil. My place is alkaline, dry and sandy and the only way those plants have arrived is in horse manure.
Further up bthe valley, where the soil turns to clay, they're everywhere.
Here's a thread on the Australian Permaculture Institute (PRI) forum that might help:
one thing to remember is if you are bringing in products from off site, you may get plants growing that aren't really indicators of YOUR property, but the property you are bringing your products from..such as mulch, manure, hay, etc..
Bloom where you are planted.
Great graphs on this in the edible landscaping book by Kourkis .
Very straightforward book, not rambly. a little older, but a good read for us sciencey types. lots of fruit tree tables too. Works well with the HP Books for Fruit trees of the West, and HP book on Trellises and Espeliers. More i look at espeliers, the more i like. Good food, and takes up so much less space, while putting shade where you want it.
