afs-71725	Sillanpää, Mikko; Lakanen, Esko	Trace element contents of plants as a function of readily soluble soil trace elements	1969	8	.pdf	application/pdf	3322	258	58	Comparisons of soluble major nutrients ofsoils with those absorbed by plants have supported the use of this method in evaluating the availability of major nutrients in acid soils (Keränen, Barkoff and Jokinen 1963, Takanen 1963). In general, the availability of soil Mn is largely dependent on soil pH. In acid soils, like the soils in this study, the available amounts of Mn generally far exceed the require- ments of plants.	cache/afs-71725.pdf	txt/afs-71725.txt
