Weed detection methods and weed spatial variability mapping with the aid of sensory technique

No small facilities are spent on the weed control for each year. Many projects and papers point at patches weed infestation. The weed control based on the weed recognition and herbicides variable application could represent a large economic saving for the farmers and also reduce amount of herbicide in the environment. Presently, variable application is seldom practiced. Potential of remote sensing and sensors as a toot for detecting and quantifying of weeds is based on several principles and levels, from aerial pictures to ground sensors platform. The main aim of this article is overview of basic principles of weed detection and weed mapping. Developing trends of weed spatial variability mapping have been also described.
