FIELD: agriculture.
SUBSTANCE: method comprises treatment of the upper layer of the substrate of outdoor sports grounds with aqueous reagent solution. The reagent is used as 1% aqueous solution of hydrogen peroxide. Treatment of the upper layer of the substrate of sports grounds with grass surface is carried out by sprinkler irrigation with the cycle of 5 irrigations a day in amount of 20 tons per one irrigation. After treatment with the reagent the organic mass exfoliated on the surface of outdoor sports grounds is removed, a break of two days is maintained in the treatment. Then the cycle of treatment of the grass surface is repeated also by sprinkler irrigation with 1% aqueous solution of hydrogen peroxide and, if necessary, overseeding of seeds of sod-forming grasses is carried out to restore the grass surface of outdoor sports grounds.
EFFECT: method enables to increase the intensity and to reduce the time of formation of grass surface and to simplify the maintenance of grass surface.
