  2. Precision agriculture - Wikipedia

    en.wikipedia.org/wiki/Precision_agriculture

    Precision agriculture uses many tools, but some of the basics include tractors, combines, sprayers, planters, and diggers, which are all considered auto-guidance systems. The small devices on the equipment that use GIS (geographic information system) are what makes precision agriculture what it is; the GIS system can be thought of as the ...

  3. Information and communications technology in agriculture

    en.wikipedia.org/wiki/Information_and...

    Geographic information systems, or GiS, are extensively used in agriculture, especially in precision farming.Land is mapped digitally, and pertinent geodetic data such as topography and contours are combined with other statistical data for easier analysis of the soil.

  4. Variable rate application - Wikipedia

    en.wikipedia.org/wiki/Variable_Rate_Application

    Variable rate application can be either map based or sensor based. Map based VRA is pre-planned, and applications are based on VRA prescription maps that an agronomist or advisor prepares based on data sources. Prescription maps can be created using electromagnetic induction, which is considered to be cost-effective, and non-destructive. [4]

    en.wikipedia.org/wiki/StarFire_(navigation_system)

    StarFire is a wide-area differential GPS developed by John Deere's NavCom and precision farming groups. StarFire broadcasts additional "correction information" over satellite L-band frequencies around the world, allowing a StarFire-equipped receiver to produce position measurements accurate to well under one meter, with typical accuracy over a 24-hour period being under 4.5 cm. StarFire is ...

    Its products and technology are used in agricultural, marine, surveying, GIS mapping, and machine control markets. [2] Founded in 2013, it was created after Beijing UniStrong Science & Technology acquired Hemisphere GPS, which was subsequently renamed AgJunction. [3]

  7. Precision viticulture - Wikipedia

    en.wikipedia.org/wiki/Precision_viticulture

    Precision agriculture emphasizes "doing the right thing, in the right place, at the right time", and is practical for viticulture because of high local variability of conditions within vineyards, and because of responsiveness to intensive management in terms of increased grape yield and quality.
