Grasslands in the Soviet Union amount to about 370 million hectares, of which some 70 million are devoted to hay, the remaining 300 million being grazed. That the wide range of climate and soil types should be reflected in the variety of grassland problems is inevitable. The present article reviews the contributions of the Timiryazev Agricultural Academy and discusses many of the problems related to the use of fertilizers on grassland in the Soviet Union.
