INFO 8: Uses of Satellites in Agriculture

[ibnuasad]

Countries have also used satellites to improve agriculture. Satellites are now being used to distinguish crops from weeds, and healthy plants from sick ones with the help of infra-red vision. Satellite based navigation, such as GPS(Global Positioning System) which was developed by the military, also assists in the process. With this, farmers can keep track of precisely what they're putting as they plant, fertilize and spray. A farmer now also has the ability to take account of such differences as different kinds of soil, varying in acidity, organic content, and nitrogen levels( all meriting different treatment). Also, differences of drainage and treatment can be determined. All this improves yield and prevents the waste of valuable chemicals. American, Russian, British and French concerns are already selling satellites or access to these satellites to farmers and corporations. This practice is well established in America, where over a dozen companies sell receivers and navigation equipment. The most noted is the John Deere "Green Star". It is an array of GPS(Global Positioning System) navigation, crop mapping and monitoring gadgetry.

See? I told you satellites were used for much more than just TV and Internet. There are many scientific uses for satellite. Without being too specific, frequency is the most common, which is why satellite can make everything go faster.
