Extract

A comparison of four methods for the determination of the exchangeable hydrogen content of soils was carried out on 157 soils, from twenty-one profiles and representative of four soil types.

The methods employed were those of: (1) Hardy & Lewis, (2) Mehlich, (3) Bradfield & Allison, (4) Schofield.

The best agreement was obtained between methods (2) and (3) which are also the simplest to apply.

A positive correlation was found between low values given by method (1) and the organic matter content of the soil.
