afs-71587	Sillanpää, Mikko	Trace elements in Finnish soils as related to soil texture and organic matter content	1962	7	.pdf	application/pdf	2880	186	63	Organic soils have often been found to be low in total trace elements, while relatively high concentrations, of some trace elements may occur in mineral top- soils rich in organic matter (4, 8, 17, 22). The total contents of many trace elements are generally low in Finnish peat soils, and particularly in Sphagnum peats, (20, 21); most of the Cu-deficiency cases, for example, are found in organic soils (18, 19).	cache/afs-71587.pdf	txt/afs-71587.txt
