Abstract
Experiments were carried out at Lafayette, Indiana, USA to investigate the relationship between initial P content in the soil sol. and P flux into the root. Panicum miliaceum was sown on 5 soils each of which was adjusted to 6 different available soil P (Cli) contents by application of P and also grown in sol. culture to determine the relationship between P influx and P conc. of the sol. A curvilinear relationship was found between P influx and the relative yield of the Cli contents on each soil. A P influx of more than or equal to 16 pmoles/cm s was needed to obtain 90% of max. yield. However, yield response was not correlated with Cli, indicating that Cli was not a suitable indicator of P availability on these soils. Influx of P on soils with <6 mu M Cli was greater than that which occurred with similar P contents in sol. culture, indicating that P influx was increased by the effect of the root on the soil
