Popis:	The potassium (K) status of 22 soil samples from 12 pedons originating in 6 Pacific Island countries has been investigated by several techniques. The total K contents of the soils studied were found to be low to very low. Use of various methods available for measuring exchangeable cations in soils showed exchangeable K to be dependent on factors such as ionic strength and displacement cation of the extracting solution. The proportions of non‐exchangeable K that are plant available were found to be very low for most soils. Data obtained from quantity/intensity measurements suggest that the soils would be responsive to added K.
