OBTAINING STABLE GRAIN YIELDS IN SIBERIA AND KAZAKHSTAN

article examines the relationship between year-to-year variability in average grain yields, moisture conditions, and the quasi-two-year precipitation cycle for a number of oblasts in West Siberia and northern Kazakhstan. The potential for obtaining stable grain yields for the region as a whole is based to a considerable degree on differences in atmospheric moisture in June and July between northern Kazakhstan, on the one hand, and in West Siberia, on the other: a harvest shortfall in some oblasts may be compensated by abundant harvests in others (translated by Jay K.
