afs-71673	Kaila, Armi	Potassium status in different particle size fractions of some Finnish soils	1967	12	.pdf	application/pdf	5739	210	63	Yet, thisrelationship is, obviously, not connected only with the texture of the soil, since there are clay soil samples (e.g. Le 1 c and Sa 1 c) 48 in which the potassium contents of the clay and silt fractions are equal, and silt soils (e.g. To 1 a and c) with a higher content of potassium in the clay fraction than in the other ones. In the 30 samples of clay and silt fractions and the 28 samples of fine sand the average potassium content (with the confidence limits at the 95 per cent level) and the corresponding minimum and maximum values are the following: Mean Range <	cache/afs-71673.pdf	txt/afs-71673.txt
