The article presents data of research on conservation and improvement of soil fertility using precision farming technologies. The study was carried out under conditions of humid climate (North-West of Russia, Leningrad region). Technologies for differentiated application of nitrogen fertilizers were tested in the fields of the Agrophysical Research Institute. In comparison with high-intensity agricultural technologies, differentiated fertilizer application was used, which was carried out with the help of a solid mineral fertilizer spreader with an on-board computer and GPS Amazon ZA-M 1500. Precision farming technologies had slightly more complex modifications. They were characterized by the introduction of increasingly informative methods of differentiated use of nitrogen fertilizers, which reduced fertilizer doses. New instruments, equipment and technologies were used, including the use of an N-sensor optical instrument, aerial photographic maps and calibration test sites with predefined nitrogen doses.
