Water-retaining roughnesses (holes, non-continuous furrows, micro-lagoons) come into being on the field surface at its tillage.They prevent a backflow, an erosion on slope lands and improve moisture content the soil.However, in the last decades such methods of a soil tillage are not used and the equipment for them are not manufactured.The author offered a new method of 1958 impala continental kit soil tillge with strips interchange (subsoil tilled and with the vegetable remains which are covered by the soil) in which cutout spherical disks form water-retaining non-continuous furrows.For this purpose harrows with two-disk and three-disk sections were developed.

Two-disk sections in a front row contain needle disks and one spherical, and in a back row - needle and cutout spherical ones, forming a stank in a furrow.Three-disk sections in a front row contain needle disks, and in a back row - two needle and cutout spherical ones.A furrow part limited to its stanks is 4-5 times longer than a stank.A nonmoldboard loosened strip is wider than a strip with the covered vegetable remains and a non-continuous furrow.However, the general width does not exceed 0.

4 m.In case of conservation tillage by a harrow with two-disk sections with spaces between disks 180 and 250 mm and 10 cm deep spherical disk non-continuous furrows can save up 216 and 155 cub.m of water per 1 hectare, and with three-disk at the same spaces - 144 and 103.7 cub.m respectively.

At a disk approach angle of 20 degrees and 14 cm deep disks the j??kaapin raikastin capacity of furrows increases by 1.6 times.
