Grebneobrazovatel is made by GR-4 according to the license of one of the leading European equipment manufacturers - Baselier (APH Group, Holland).
It should be noted that the cross-sectional area of the crest formed by a lancet paw of a standard cultivator-okuchnika makes 0,042-0,046 sq.m that is twice less than the area of the crest made by a grebneobrazovatel of GR-4.
Incorrectly created crest can lead to undesirable consequences - to its destruction under the influence of atmospheric factors. It will lead to a vylezaniye of tubers from the soil (potatoes gain green color and, as a result, completely loses the commodity value).
Thanks to processing of the soil grebneobrazovately GR-4 the landing tuber is in the middle of a big and friable crest which soil and air conditions in the best way promote development of powerful root system of potatoes, an active stolonoobrazovaniye and a klubnenakopleniye. In such high-volume crests of a plant are almost not subject to influence of bad weather conditions (a drought, remoistening) that guarantees annual receiving steady harvests. In these conditions even the excessive soil moisture collecting in row-spacings at the basis of the crests which are not able to influence negatively formation of a harvest.
