Summary

The total P contents of soils, analysed after fusion with sodium carbonate, were consistently larger than after digestion with boiling perchloric acid. For 37 soils from southern England, values by fusion analysis (Pf) were related to values after digestion with perchloric acid (Pp) by the following equation:

The recovery of P, applied to six soils as superphosphate, was the same by both methods of analysis.
