Precision agriculture is a farming management strategy based on observing, measuring and responding to temporal and spatial variability to improve agriculture production sustainability. it is used in both crop and livestock production. The significance of all this technology is to enhance farming so that, there will be more productivity, which will intend led to more profitability.Precision agriculture has also been enabled by unmanned aerial vehicles that are relatively inexpensive and can be operated by novice pilots. These agriculture drones can be equipped with multispectral or RGB cameras to capture many images of a field that can be stitched together using photogrammetric methods to create orthophotos. Geolocating a field enables the farmer to overlay information gathered from analysis of soils and residual nitrogen, and information on previous crops and soil resistivity.Remote sensing technologies provide a diagnostic tool that has at least two important functions as well as many other uses in site-specific management of crops. Remote sensing can be used to measure reflectance of light energy from crop canopy, which may be useful in detecting plant stress while there is still time to correct the problem. Yield monitors are an essential component of many site specific management strategies. Yield maps, the visual and numerical product of yield monitors, encourage creative investigation and can provide reliable answers to carefully performed on-farm experiments.
