The fertilizer experiments reported in this summary were performed on representative soil types in the major crop areas of the state. The growing season in 1956 was characterized by the occurrence of drought in the spring and early summer. The drought associated with high temperatures, in early June seriously reduced small grain yields. The above normal rainfall in the early part of August was very favorable for the development of the corn crop, the southeast corner of the state did not receive these rains and the drought continued through the summer.
