Getting Started Precision farming teaches farmers to base their decisions on harvested information; it is the leading edge of farm management technology today, and begins with the collection of accurate field data. Highly varying yields within a field indicate that the current farming practices may not be providing the best possible growing conditions everywhere in the field. Therefore, the more information you have about your field, the more factors you can control in order to make better decisions about the factors you can’t control. The process of associating data with geographic coordinates is known as georeferencing. The most common georeferencing method for recording the location of sites within a field is through the use of satellites collectively known as the Global Positioning System (GPS). GPS satellites transmit longitude, latitude and altitude signals necessary to pinpoint exact locations on Earth. A mounted receiver on the tractor or combine calculates the machine’s position in the field, allowing the farmer to coordinate exact field locations with field activities. Field equipment (both machines and implements) can be equipped with sensors which measure values such as average yield, average moisture, seeding rates, tillage depths, and pesticide rates. This data is matched to the corresponding longitude, latitude, and altitude which is gathered by the GPS receiver affixed to the top of the combine or tractor cab. All the gathered information is then taken to a personal computer where it is processed into text reports and visual maps. Farmers can now see exactly where the best - and worst - areas of their fields are, which helps them to farm smarter by making better decisions. In addition, the farmer’s pocket notebook will be replaced with expansive crop recordkeeping, making it easier to provide the necessary information to the Environmental Protection Agency (EPA). The primary goals of precision farming are maximizing profits by applying the right amount of inputs in the places needed to sustain a high crop yield, and enhancing environmental stewardship. 13
