METHOD OF AGROCHEMICAL INSPECTION OF SOIL Russian patent published in 2016 - IPC G01N33/24 

FIELD: agriculture.

SUBSTANCE: invention relates to agriculture, namely, to agrochemical mapping of soils. To do this, the edge detection is carried out on the results of remote sensing of fields with the subsequent transfer to the land use maps. The edge detection on the results of remote sensing of fields is carried out on multispectral high resolution satellite images with the clustering method based on the difference of light reflection of objects. The detection of elementary plots for the soil sampling with their transfer to nature is carried out based on the difference of light reflection of objects. The image of the objects under study is created in the form of electronic cartograms. The calculation of the ratio of the light intensity of the object under study to the values of long- and short-wave part of the spectrum of solar radiation on the points of soil sampling is carried out by multivariate analysis.

EFFECT: invention enables to apply widely the differentiated system of improvement of soil fertility, which increases productivity of field crops by 20-30%.
