Agroclimatic studies in the Soviet Union, initiated in the 1920's, were built upon preceding works of Russian meteorological pioneers. During the Soviet period, indices have been refined to relate plant responses to specific climatic factors, and methods have been devised to derive desired indices from standard climatic data. Agricultural appraisals have been made of the climate over the entire territory of the Soviet Union, and maps have been constructed to show agroclimatic regions. Agroclimatic analogs have been developed for many crops and methods of agrometeorological prognosis have been perfected.
