I used red clover/sweetclover plowed down to help break up my clay. If the soil's too wet they won't grow that well. You could grow corn, soybeans, wheat or oats in the drier areas. Clay is difficult; if you try to work it when it's too wet you break down the soil structure, if it's too dry it's like concrte. There's only a small period of time when you it works well. Fall plowing also helped me get some of the first crops in. Now after 18 years, my soil has turned a nice brown/black colour instead of the red that I started with.

You may want to plant shrubs like Dogwood and trees like willow/poplar in the wetter areas.
