A method for cultivating the soil after seedling emergence includes the beginning of executing the work, when plant rows had appeared or at full seedling emergence thereof, duration of the work is 2 days ( 1 day), a width of a protective zone on each side of a row is 60 mm ( 20 mm), the amount of undercut and covered plants is 0% (+5 %), controlling weeds in interrow spacings is 100% (-4%), in the protective area of the rows is 55 % ( 15 %); soil dispersion: the amount of clods of above 20 mm in a diameter is 5% ( 5 %). The loosening of the soil in the area of rows and area of interrow spacings is carried out for the optimum depth avoiding damaging the root systems of the plants. The loosening of the soil in the area of rows and the area of interrow spacings is determined depending on the depth of placing the seed sown. The necessary amount (according to the weight) of agrotechnically useful particles of the soil of a diameter d up to 10 mm in the surface loosened soil layer is determined depending on the depth of loosening thereof in the area of rows.
