Abstract

Barley (Hordeum vulgare) and rye (Lolium multiflorum) plant were grown in phosphate-treated soiland in an equilibrium nutrient solution which circulated continuously through soil potsand sand pots. The plants in soils always grew better and accumulated more phosphorus than the plants in sand. Plant physiological tests showed that the sand plants did not measureably deplete the circulating solution; therefore, the cause of this two-phase effect must have resided in the soil.
