A method of increasing crop productivity, including in the areas of risk farming, based on sowing time optimization, noted for the seeds being placed in the wet overmoistened and / or slurry-type soil, perhaps under the rain, right after the rain or immediately after the snow cover melting, the sowing unit traveling speed being 1-60 km h, provided that a technological transport vehicle capable of operating under pressure on soil of 0,4kgf cm2 or less up to zero, for example, "Bars UTES 271" on the elastic tyre covers or the air-cushion device is used as a sowing unit power device. In this case the seeds are placed just under the overmoistened soil layer with the depth of penetration being from 0,2 to 15 cm.
