Continuous loosening of the soil can be carried out, using rotational batteries. Thus it is possible to carry out at the same time small loosening of the soil in row-spacings (4-6 cm) paws razors (. This work is carried out in a phase of well developed fork - the first couple of leaves.

Thus it is necessary to consider that in the course of vegetation of 10-15% of plants for various reasons drops out (degree of a natural izrezhivaniye). Besides, at the mechanized formation it is possible to increase density by 5-10% still.

The unit is conducted on sledoukazatel or the cracks formed when sowing on the center of row-spacings between the 7-8th or 8-9th rows. In the absence of sledoukazatel crops process across or on a field diagonal. Speed of the movement of units - 7-12 km/h.

For destruction of a soil crust to harrow after rainfall more effectively. If sprouts of beet grew into a soil crust or rest against it, processing of the soil should be carried out rotational working bodies (rotational RB-5 batteries, with which equip USMK-5 cultivators,

The first loosening of the soil of row-spacings (sharovka) is carried out on depth of 3-4 cm at designation of rows of beet in a fork phase - the beginning of formation of the first couple of real leaves with a speed no more than 4-5 km/h. At high-quality performance of work the protective zone makes 7-8 cm.

After completion of works on formation of density of standing of plants when beet has 2-3 couples real leaves, loosening of the soil in row-spacings on depth of 6-8 cm is carried out by the same unit. If necessary top dressing is carried out by liquid or dry fertilizers.

It is necessary to watch that working bodies of prorezhivatel and cultivators were not buried to the soil more than at 3-4 cm. At bigger deepening the part of root system remains, and plants again get accustomed. With a smaller depth, especially friable soil, plants "are smoothed down" and remain viable.

The last processing of the soil in row-spacings is carried out in 2-3 weeks prior to cleaning, in the second half of August - the beginning of September, on depth of 10-12 cm - to 1-2 receptions. It promotes the intensive growth of a root crop, accumulation in it of sugar and considerably improves quality of work of beet-harvesting complexes.

In the beginning clean plantations of early crops, with physiologically more mature plants at which leaves turn yellow and die off. Beet of later crops with well developed green leaves is cleaned later.
