Extract

1. The application of the zinc uranyl acetate method to the determination of exchangeable sodium in soils is discussed.

2. Using this method of determination, good agreement was found between the exchangeable sodium extracted by 0·5 N acetic acid and that extracted by N ammonium chloride.

3. The procedure for estimating sodium in acetic acid extracts is described, and the results for a number of typical non-saline Welsh soils are given.
