is it important to get the clods and rocks out?
I'm in the process of converting a section of yard into a place to plant veggies next year. I did a small section of it (maybe 1/6 of the available space) which took me several hours of hard work. I dug up maybe 5 inches of grass, red clay, and rocks. I seperated most of the rocks out and broke up all the clods (which are almost as hard as rocks). I intend to mix in some composted manure and top soil and cover it with newspaper,then let it sit til next spring. My question is...how nessacary is it to break up all the clods and remove the rocks? It seems to me they would impede root growth. I don't mind doing the hard work as long as it is beneficial!

IME, clay only becomes cloddy if worked when it is not dry. If it is allowed to dry completely, you should have a clod larger than a big pebble.
As far as this winter goes, if you are far enough north for any solid freezes (4-6" deep) any clods you create this year will melt by next spring. Another good amendment would be crimson clover. Inexpensive, fixes nitrogen, makes a great winter cover crop, can be mowed and then turned under in the spring, adding lots of organic material to the soil.
I always remove large rocks and even smaller ones (golf ball or larger) when I find them. A few rocks never seem to bother plants.

You don't have to have perfect soil the first year. I have/had big clay clods and rocks, and no tiller. Most big plants will grow fine in with the big (apple sized) clods and rocks. They send roots into cracks in the clods and help break them up. Things like onions, garlic, lettuce etc might have problems in rough soil. I spade turn the garden spring and fall and let the clay clods dry in the sun for a few days and then whack them with a shovel to shatter them. Rocks dry out faster than the soil so can be easily seen on top a few days after turning. I have paved the walk ways around the plots with the rocks take from my soil, and after three years of picking, the rocks are down to saltine cracker size and there is more soil than clods.

I can second that...wordwiz wrote:IME, clay only becomes cloddy if worked when it is not dry. If it is allowed to dry completely, you should have a clod larger than a big pebble.

I tilled up a garden spot for the first time this year.... added in a couple 4 x 6 x 4 trailor loads of horse manure (from stables) Ground got very nice, and I am excited about the planst it is producing.
I did (one time till my soil when it was too wet, and it codded up, and then got "hard as a rock". When it dried out I tilled it again to help solve the problem. So if you live where there is a lot of caly soil (like I do in GA).. never till the ground if it is wet.
My Dad has a garden behind his house... he's been planting it in the same place now for about 10 years... his soil is fine a pebbles. So easy to till, and hoe out weeds.
I'm talking clay, not clay soil. Here it shows up as a layer below the topsoil, and can start from just under the sod to about 9" deep. Dry clay has to be chipped out, moist clay needs to be sliced out. Clods are either dry enough to shatter with a sharp blow or have to be sliced up into smaller clods. Sometimes a big clod will separate into pieces if some roots penetrate the right way.
