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.
