Abstract

In recent years it has been shown, through the use of commercial ion-exchange material, that plants are able to utilize nitrate ions incorporated in soil or nutrient culture in an adsorbed state (Schlenkler, 1940, 1942; Converse, Gammon and Sayre, 1943; Graham and Albrecht, 1943; Jenny, 1946; Arnon and Grossenbacher, 1947; Hunter, 1948). In view of the apparent adsorptive power of pumice (Veller and Arutyunyan, 1933), it was of interest to determine whether this material could be utilized in plant nutrition studies to supply nitrogen as adsorbed nitrate. Although preliminary experimentation showed that the nitrate fixing capacity of pumice was very low, it did not indicate what portion of this nitrate was available for plant absorption. It was for this reason that this investigation was undertaken.
