METHOD FOR IMPROVING WATER-PHYSICAL PROPERTIES OF SOIL WITH LIGHT GRANULOMETRIC COMPOSITION Russian patent published in 2001 - IPC

FIELD: agriculture. SUBSTANCE: method involves introducing into soil finely-dispersed material for increasing content of physical clay in soil. Finely-dispersed material is produced by grinding soil adapted to be improved in the field within ball-type mill. While finely-dispersed material is introduced into soil, it is mixed with plow layer of soil. Method allows costs for finding, buying, transportation and introduction of finely-dispersed material to be reduced. Moreover, greater soil fractions are intensively involved into soil formation process. EFFECT: increased efficiency and improved quality of soil.
