Precision Farming in Minnesota

NASA (Jesse Allen); USGS; Link:

This false colour image shows farms alongside the Buffalo River in the US state Minnesota. Among other things, the term “precision farming” refers to the monitoring of plant health with the help of satellite images. Due to the depiction in the infrared spectrum, the farmers are provided with a lot of information about their fields.
Yellow areas indicate cultures that have been attacked by vermin, shades of red stand for healthy vegetation and black signals that there is too much water in the ground. What is more, weeds and hail damage can be detected by means of remote sensing as well.
