Abstract

A root bioassay of soil P availability, based on the amount of ³²P‐labelled phosphorus taken up in 15 min from a solution in the laboratory, has been tested on seedlings of winter wheat (Triticum aestivum L) and spring barley (Hordeum vulgare L). The seedlings were taken in spring from six different fertiliser plots, selected to give an extreme range of P availability, from the Broadbalk and Hoosfield experiments at Rothamsted. The results showed a negative relationship between the rate of phosphorus uptake and (a) the phosphorus contents of plants, and (b) Olsen's bicarbonate extractable phosphorus of the soils. This pattern is consistent with the results previously obtained when determining the phosphorus status of trees and grasses. This rapid bioassay procedure may therefore be applicable to agricultural crops.
