METHOD OF RECOVERY LEVELLING FOR FIELD WITH MELIORATION SYSTEM Russian patent published in 2008 - IPC A01B79/02 

FIELD: agriculture.

SUBSTANCE: for recovery of a rice levee melioration system it is plowed to the plough-layer. Then the levee is flooded by portions to cover the plowed depth, followed by rotatilling of water-saturated soil till complete hydration and forming of thixotropic mass, and air feed into the tillage tool operation zone. Further, during sedimentation, settled water is gradually discharged to a channel. At the last run of rotatillage machine, a microbiological preparation is infused together with air into operation zone of the tool. The preparation is a complex of microorganisms adapted to the conditions propagating destruction and mineralisation of organic complexes produced during hydration of water-saturated plough-layer. For example, an EM-1 Vostok microorganic complex can be used. This technology allows decrease of recovery period, improve leveling quality and eliminate plant residues without the use of pesticide and fertilisers.

EFFECT: faster recovery of a field with melioration system with improved leveling and harmless destruction of plant residues.
