METHOD OF SAMPLING FOR ANALYSIS OF SOIL OF MEADOW Russian patent published in 2014 - IPC G01N33/24 

FIELD: agriculture.

SUBSTANCE: method comprises determining the place, frequency, duration of soil sampling from the surface layer of 0-5 cm at areas on the coordinate grid, indicating their numbers and coordinates. The places of soil sampling are centred of the hollows and hillocks with irregular coordinate grid, at each node of the irregular coordinate grid or its part in the middle of the hollow or the hillock the area for soil sampling is created of the symmetrical form with rows of soil sampling points symmetrically located relative to the boundaries of this area. The sampling areas are located at the lower part of the hollow or at the upper part of the hillock on the centres with alignment of centre of the area with the centre of the hollow or the hillock.

EFFECT: method enables to assess quickly and accurately the quality of the surface layer of soil covering on the coastal meadows, within the water protection zone of a small river, and on the uneven surface of hayfields and pastures with hollows and hillocks on meander, central and terrace near flood river floodplains.
