✦ Synopsis

Phosphate residues in the soils of some manurial trials at Samaru, northern Nigeria were assessed as L and E values and by the isotopic-dilution factor. They gave significant correlations with yield and P uptake in a pot experiment. The E values, which were useful only when measured in the presence of carrier phosphate, and the I.D.F. values were both better in assessing the availability of residual phosphates t h a n were L values on similar soils.
