Description
Five grassland site types are distinguished: Chestnut soils are covered with natural forb or grass steppes producing 0.1 to 1.0 t DM/ha at less than 300 mm annual precipitation. They should be exclusively used for winter grazing. At higher precipitations, these soils will tum into permafrost soils. They bear mountain herbage vegetation as forest substitute associations. Productivity amounts to 4 t/ha. Mowing and/or grazing are possible. Fertilization seems to be profitable. Between grass steppes and mountain herbage lands we find extended meadow steppes located on shallow chemozems. Old, intensively grazed pastures in the lowlands have become depleted in nutrients. Nitrogen fertilization increased the yields to several times the original level. Site-adapted pasture plant ecotypes provide good initial material for grass breeding in Mongolia.
