The beautiful green hills of Palouse are one of the largest producers of wheat in the country, producing 153.2 million bushels. The abundant rainfall, fertile volcanic soils and moderate climate help, but it certainly didn't get to this scale by practicing organic farming.
Here we see a crop duster on one of its many runs spraying insecticides on a field of wheat, getting dwarfed by the vast rolling landscape all around.
