I am also very interested in the biology of the soil. Because if that is right, the plants will be ok. I don't like putting harsh chemicals on my plants or soil. And I've seen enough evidence that soil health is very important.

Speaking of which, when turning what subs as a compost bin (more like a pile), I noticed an unusually large number of grubworms the other day. I want earthworms, not grubworms. Anybody have any good ideas on an organic (but inexpensive) solution for getting rid of them while preserving the earthworms?
