Abstract

Large areas of irrigated farmland in southwestern Idaho and southeastern Oregon contain scattered small areas of nonproductive, salt-affected soil. The peculiar spots are areas of naturally occurring solonetzic soil, containing excessive amounts of adsorbed sodium and soluble salts. Because of the clayey nature of the tilled soils and the persistent wetness and slick condition of the affected soils following rains or irrigations, the soil areas are commonly referred to as "slick spots." In the irrigated croplands the slick spots appear as areas of very sparse and stunted plant growth in otherwise productive lands. The poor plant growth is attributed to the unfavorable physical condition and extremely low rate of water infiltration during irrigations. The low water infiltration capacity results from the deteriorated soil structure caused by the high exchangeable sodium, particularly in the shallow clayey subsoil or B horizons of the soil.
