observed usually in spring, it is thinner in winter, with the
prolonged thaws, when water from the melted snow in the lowered places
on the weakly-water-permeable soils submerges plants. The
flooded by water, badly tempered from the autumn plants for lack of
oxygen in 7 10 days turn yellow (disintegration of chlorophyll), they
accumulate in the cells ethyl alcohol, which causes poisoning, and in
two weeks perish. To warn v. r. is possible by sowing steady it

sowings, by the application of ridge sowings and by other agro-tech.
