METHOD OF PHOTOMETRIC DIAGNOSTICS OF NITROGEN NUTRITION OF PLANTS USING UNMANNED AERIAL VEHICLES (DRONES) Russian patent published in 2018 - IPC G01C11/02 

FIELD: agriculture.

SUBSTANCE: invention relates to agriculture. Method of photometric diagnostics of nitrogen nutrition of plants using unmanned aerial vehicles (UAV) for averaged over the field of application of nitrogen fertilizers with preliminary calibration of photometric N-testers in the plots of standard field experiments with increasing doses of nitrogen is characterized by the fact that diagnostics is carried out in cameral conditions from photographic images of fields from unmanned aerial vehicles equipped with conventional digital video or cameras, with a subsequent assessment of the supply of plants with nitrogen supply by portable N-type testers of the “Yara” type by determining the intensity of the green coloration of certain parts of the image on a paper basis to determine the average dose of nitrogen and issuing recommendations on the doses of nitrogen fertilizers in accordance with the level of supply of plants with nitrogen nutrition and accepted agricultural technology.

EFFECT: technical result consists in reducing the complexity and laboriousness of vegetative crops, as well as increasing the productivity of work.
