<span>Grains, as a whole, remain an
important part of the Russian economy. The types of grains produced,
however, vary with changes in demand and environmental conditions. Some
grains, such as oats, supported Russia economically in the past, but
grow in much smaller quantities. While grains export in highest
quantities from Russia, legumes follow close behind. Hardy and resilient
legumes, including potatoes and beets, prove ideally suited for
Russia's cold climates and sub-par soils. Potatoes thrive at Russia's
northernmost locations, primarily regions between 50 and 60 degrees
latitude. Russian potatoes provide citizens with food and nutrients, and
support vodka production as well. </span>
