English: The Odd One Out – Alone in a monoculture Until the coming of modern weed killers corn fields would have been been full of poppies and other weeds. I estimate this field has some 15 hectares of wheat and from the footpath running along one side the only weed I could see in the crop was this one lonely poppy forming a tiny red dot. I didn't even sea a single ear of wild oats. Even the headland (the grass area between the crops and the hedge) had a limited number of plant species growing on it.
