The fertilizer experiments reported in this summary were conducted in 16 counties in South Dakota. These experiments were located on representative soil types and were conducted in the major crop areas of the state. The growing season in 1955 was characterized by above normal temperatures and below normal rainfall. At the beginning of the season the subsoil moisture was about normal for most of the state. The effectiveness of the crop season rainfall, however, was reduced by excessive evaporation due to strong winds and high temperatures. Small grains were injured especially by the May drought which placed a ceiling on final yields in most areas. Associated with the dry climatic conditions, however, was the lower incidence of plant diseases which had a beneficial effect on crop quality.
