Terra GranaLogo Design Contest

We are a small farm specializing in white corn. Our corn is sold to Mexican bakeries who make fresh tortillas with the corn. Terra Grana is Latin for "grains of the earth." We are looking into branching into other areas of agriculture, possibly including chickens, turkeys, and vegetables. Corn therefore might be a part of the logo (either the ear or the kernel), but I'd like to find a way to work other aspects of the business into the image. I am inclined to think that a more abstract image may work better than the grossly-overdone barn, ear of corn, tractor, etc. However, the image needs to connect w/ the audience. The buyers work with us because of the quality of the grain produced, the regular sterilization of the grain holding areas, and the efforts to avoid genetic cross-contamination. We want to communicate the quality of the grain (minimal foreign matter; whole, uncracked kernels; no mold) while appearing to sell something that will taste great.

Gold, green, blue, yellow, brown, orange. However, I am open to other concepts. Strangely, I have no preconceived notions about what this should look like.

I like the logos at adm.com, monsanto.com, and less so pioneer.com. Not crazy about agrigold.com 's logo though.
