metadata.value: An important stage in research aimed at solving the problems of accurate farming is the
  laying of field experiments. A necessary condition for carrying out such experiments is to
  ensure homogeneity of the selected land plot. Most of the existing techniques for isolating
  homogeneous zones for conducting experiments are based on costly and labor-intensive
  sampling and analysis of soil samples. An alternative and promising approach is the use
  of an unmanned aerial vehicle. In work, all stages of choosing a homogeneous land plot with
  the help of aerial photography are presented in sufficient detail. The object of the study
  was a field with a long-term sowing of “goat” on the basis of the Menkovsky branch of
  the Agrophysical Institute (Leningrad region). Aerial photography was carried out in 2015–
  2017 with the help of an unmanned aerial vehicle “Geoscan 401”. The received data were
  processed with the help of specialized software: crosslinking and alignment were carried out
  in the Agisoft PhotoScan program; the thematic processing and allocation of homogeneous
  areas of the field were carried out in the programs QGis and Saga Gis. To assess the state of
  vegetation, the vegetative index NDVI (Normalized Difference Vegetation Index) was applied.
  To cluster the homogeneous parts of the field in terms of NDVI parameters the ISODATA
  algorithm (Iterative Self-Organizing Data Analysis Technique Algorithm) was applied. The
  paper presents the results of clustering images of the same field in different time periods.
  In the course of the work, intersections of these aerial photographs were constructed, four
  clusters were identified, which are the intersection of the corresponding homogeneous zones
  for the considered time periods. Accordingly, the laying of experiments is expedient to be
  carried out on these sites, since the homogeneity present there seems more stable in dynamics.
