METHOD OF SEPARATION STRUCTURAL UNITS OF SOIL Russian patent published in 2013 - IPC G01N33/24 

FIELD: agriculture.

SUBSTANCE: method includes separation of air-dry aggregates. The separated aggregates are destroyed to the size smaller than 0.25 mm, moistened, dried, the self-collected structural units are separated from the structureless particles by circulating shaking (1.5 hours, 25 rpm), followed by sieving on a sieve of 0.25 mm and separation of water-resistant aggregates.

EFFECT: method enables to separate from the total soil mass the part which is the most active in terms of structure formation - the components capable to form spontaneously the aggregates after wetting-drying, enables to estimate the direction of aggregate formation processes in soil.
