Description	English: From space this 1,200 hundred-plus acres farm in north-west Minnesota looks like a patchwork quilt. Fields change hue with the season and with the alternating plots of organic wheat, soybeans, corn, alfalfa, flax, or hay. Made with infra-red light, this false colour image provides a wealth of information about crop conditions. To the untrained eye, this false-colour image appears a hodge-podge of colours without any apparent purpose. But farmers are now trained to see yellows where crops are infested, shades of red indicating crop health, black where flooding occurs, and brown where unwanted pesticides land on chemical-free crops.
