Joe, I agree that remineralizing soil for crop production is extremely important. Since moving heavy materials is expensive, one should do research as to what material can give the most lasting benefit per pound-mile. I don't necessarily agree about the magical qualities of "weeds" (any plant not intentionally cultivated). Most of the plants we think of as weeds are plants that thrive in a mineral balance different from that of most crop plants, IOW, they thrive in the conditions that they find. Or, to put it more accurately, the weeds that are thriving in a certain situation tell a lot about that soil and circumstance. I greatly commend to you Charles Walter's book, "Weeds, control without poisons", for much more along those lines. Around here, the weeds that normally thrive in unamended situations are adapted to acidic sandy to gravelly soils that are high in phosphate and low in calcium. As one changes that balance with amendments the suite of weeds changes dramatically, ultimately, if one gets the balance into the range optimum for crops, ending with the suite of the so-called "fertility" weeds. What I do find very intriguing is the idea that any weed is automatically working to correct the imbalances found in situ. So for example, deep-rooted weeds like the docks that thrive in acidic soils with relatively high phosphate and relatively low calcium are slowly bringing the leached calcium from the subsoil to the top aerobic zone of soil. Or at least that is a supposition, I don't know if any serious study has gone into it. It's a very attractive idea.

I've just reported another one of those spam posts. I'm sure they will be gone, soon. I wish we had a "flag this post" button like many other forum sites.

Thanks weedy. For the life of me, I didn't remember where to contact GW at. I looked all over the (top of the) page for it one time, and gave up. I wonder how many are like me and get so used to the words at the bottom, we don't actually read them. Maybe it would be good if they put the link at the top somewhere (or, like CL, in the side-bar of every post so we can just click it to mark it as spam).

Jasdip, Garden Web is owned by super company NBC Universal. They don't close down for a holiday. The moderators sure have been asleep at the wheel, though, to allow all of that spam stay for so long, though. Extremely annoying, isn't it?
