| Abstract: | The amount of K and Na in HCI-extract of soils has been determined by various methods, using the flame photometer, and specific reagents, but none of these methods are fully satisfactory from a view point of cost or accuracy; Poul Porter et al.1) have pointed out the large errors that have frequently occured in tlamephotometry. |
