The secrets of soil (aka, why we're not tilling the garden yet)

We just got back the results from our soil sample test, and we're waiting eagerly (I'm eager, the farmers perhaps are not, since they'll do the real work) -- ok, I'm waiting eagerly to till & amend the soil, based on the soil test recommendations.

Here's the problem, though -- the soil is still too darn wet! I'll keep you updated, but this next week looks a wet one as well, so no promises.

Meanwhile, soil. If you want to learn more about it, click here to check out this usenet group with a long discussion on soil for gardening. Meanwhile, some info from that site that might be helpful.

On why working with wet soil is a bad idea:

B.01.07: What is Soil Structure?
Soil structure is the way in which the sand, silt, and clay particles are grouped together. The drainage capacity of the soils and the ability of the soils to make nutrients available to the plant are functions of soil structure.

B.01.15: What is compacted soil and how is it corrected?
Compacted soil is soil with most of the air squeezed out. A good top soil should contain as much as 25% by volume air which is needed to support plant growth and the soil organisms. Tramping around in moist beds is a sure way to compact the soil and is something that is best to avoid. The passage of soil macro-organisms, and particularly earth worms, going back and forth through the soil repair compacted soils. Compacted soils can also be corrected by digging in additional organic material.

Although it may seem overly technical, I think you can never pay too much attention to your soil. It's the bedrock (joke intended) for your garden, and deserves respect.   The link above also has a terrific information on the differences between topsoil, potting soil, the difference between organic amendments and fertilizer, and raised beds.   Enjoy! And stay warm!
