METHOD OF PRODUCTION OF SUSTAINABLE GRASS CANOPY FOR LAWNS Russian patent published in 2014 - IPC A01G1/00 A01N33/02 A01G7/06 A01N59/00 A01N65/00 

FIELD: agriculture.

SUBSTANCE: method comprises the use of biologically active additive which is used as a composition comprising a mixture in equal parts by volume of aqueous solutions of the following: a hydrogen peroxide at a concentration of 1·10^-3-3·10^-3 M (3.4·10^-2-10.2·10^-2 g/l), urea at a concentration of 1.5-2.5 g/l, oxidised corn starch at a concentration of 4.5-6.0 g/l. At that the seeds before sowing are soaked in the composition and the topsoil is moistened by it once with the depth of 2-3 cm at the initial stage of vegetation. For soaking of seeds before sowing, the 1 litre of composition per 30 g of seeds is taken. In case of adverse environmental conditions the additional processing with the said composition of aboveground plant surfaces is carried out at a rate of 400-500 l/ha.

EFFECT: method accelerates the growth of underground and aboveground parts of plants and provides grass canopy the high resistance to stressful situations.
