This could be improved with a tighter crop - I'd like to see the farmer on the tractor a bit better; or from a greater distance - to show more of the landscape.
I'm glad somebody else sees this as something worth capturing with a camera. I ran across almost the identical type scene the other day coming back from work...didn't have time (or a place) to stop and take some photos. You've done well with exposing this considering the mid-day sunlight. Nice clouds working for you as well! :D Good luck in the challenge.
a wonderful agriculture photo. I like the dust kicking up, the colors are good, lighting could be a bit better but its not unbearable. Id even crop the bottom 1/5 out, as I dont think its neccessary.
