blowing by wind the top, the layer of soil together
with the poseyannymi seeds, and sometimes also with the shoots.
Is observed with the high dry winds, Vol. n. of dusty, or black,
storms. Especially strongly it is manifested on the atomized,
unstructured soils. With v. p. the part of the seeds can remain
in the soil, but they prove to be moved or biased into the heaps, as a
result is observed either the total loss of sowings or the nonuniform
distribution of shoots. Root system bares in the developed
shoots with v. p. and plants perish. V. p. most frequently
occurs in spring in the fields, zaseyannykh by spring cultures after
steam working in the previous year, and also in autumn - on the shoots
of winter crops, vyseyannykh on the clean vapors. Most
frequently v. p. is observed in the steppe regions; in THE USSR
- into Zap. of Siberia, North Kazakhstan, Bashkirya, Stavropol and
Krasnodar edges. Measures of the fight: landing tree
belts, application of correct crop rotations and of regular system of
working soil, irrigation and by other All-Union science and research
institute of grain economy for the steppe regions are developed the
methods of the nonwaste working of the soil, with which on the surface
of soil it remains to 90% of stubble, which reliably protects soil
from the blowing.
