The effective precision crop products' production is impossible without modern contact and remote optical control methods of a physiological and phytosanitary condition of crops. At Agrophysical research institute (Russia, St. Petersburg) the technique of definition of homogeneous technological areas is developted by using the means of unmanned aerial vehicles of helicopter (Geoskan-401) and plane (own development) types. Also the test plots which are used as the standards with the known parameters of a physiological and phytosanitary condition of agrocenosis are developed. On their basis the following aerial photographs' decoding is carried out and the cards-tasks (cartographic task) of the differentiated application of chemicalixation means with taking into account the revealed distinctions are formed. For definition of homogeneous contours the programs ERDAS Imagine, Photoshop CS4 Portable are used, technological cards-tasks (cartographic tasks) for the application of fertilizers are generated in a special developed GIS-ARI program's model. This technique is successfully approved in the technology of precision management of plant nutrition and phytosanitary condition of spring wheat's crops in the Northwest of Russia.
