The term "precision farming" means carefully tailoring soil and crop management to fit the different conditions found in each field. Precision farming is sometimes called "prescription farming", "site specific farming" or "variable rate technology." It focuses on the use of three technologies - remote sensing, geographic information systems (GIS) and global positioning systems (GPS).
Precision Farming has literally taken "agriculture into the space age."
Farmers have services available to them that involve satellites collecting data, transmitting location information, or providing data from a variety of sources. Farmers can analyze this satellite information or they can rely on companies to do this service for them for a fee. The real value for the farmer is that he can adjust seeding rates, plan more accurate crop protection programs, perform more timely tillage and know the yield variation within a field. As the cost of this technology comes down the cost effectiveness of
production will improve.
