METHOD FOR SOIL SAMPLING FOR AGROCHEMICAL ANALYSIS ON DISTANCES ALONG SMALL RIVER AND TRANSVERSLY FROM WATER LINE Russian patent published in 2017 - IPC A01G23/00 G01N33/24 

FIELD: ecology.

SUBSTANCE: surveyed territory as a grid for soil sampling is determined on the side of a small river within the water protection zone near agricultural landings, soil sampling points of the grid are located in places without significant anthropogenic or technogenic impact, and soil sampling sites are taken as dots on the coastal relief of natural origin, then the point of the first measurement site intersection with the water line of the small river water surface is taken as the origin of the coordinate grid, the first soil sampling points at all measurement sites are located beyond the small river coastline from the water line. At least three measurement sites along the river are located irregularly, and soil sampling points at each measurement site are regularly located at a constant distance between them, soil sampling is performed approximately in the summer runoff low of the small river, on an uneven grid along the river due to different lengths between the water line and the first sampling points on the measurement sites along the course of the small river flow, the distance between the corresponding points on the measurement sites is measured on the map, after measurements with respect to the grid for all soil sampling points according to agrochemical analysis of soil samples, two-factor statistical modeling of the chemical content is carried out depending on the distance along the grid along the river and the distance from the water line to the soil sampling points evenly located along the sites.

EFFECT: improvement of the method.
