METHOD FOR CREATING OF LONG-TERM PLANTATIONS OF LICORICE CROP AS MESOHALOPHYTE Russian patent published in 2005 - IPC

FIELD: agriculture, in particular, restoration of fertility of degraded irrigated soil with high level of mineralized ground water by phytoamelioration provided with the use of mesohalophytes.

SUBSTANCE: method involves eliminating weedage, stubble remains and rootstocks from soil surface layer to 3-12 cm depth with the help of mechanical means and extracting soil to furrow depth of 0.15-0.25 m from soil surface; cutting slots with drains at 1.1-1,4 m pitch on field surface or rice check; discharging water by means of drains into adjacent ditch or special channel; mechanically removing weedage, stubble remains and rootstocks by performing rotavation of top layer above slots by providing strips of 0.4-0.6 m width; forming triangular furrow above slot; laying soil-and-humus substrate into open furrow and covering laid substrate with layer of soil, which had been earlier extracted from furrow; covering soil and substrate by means of covering roller; sowing licorice seeds of local ecoforms to 2-3 cm depth at seeding rate of 5-6 kg/hectare in rows; shifting rows from slot mid portion by value exceeding slot width by 6-8 times.

EFFECT: reduced level and mineralization extent of ground water.
