Precision Agriculture covers a research area with the goal to optimize agricultural production system in both time and spatial dimension.
In practice, PA changes the way a farmer works:
. Yield are not only harvested but also mapped
. Soil sensing gives information on soil status
. Tree/crop sensing for tree/crop growth information
. Fertilizer/pesticide apply according to local demand
. Use new technique like DGPS/GIS, EM method,
   ultrasonic sensors, remote sensing, NIRs, multispectral
   and hyperspctral images, yield monitors  and varibale
   rate spreaders/sprayers
. Information technology supports decision making.
