afs-71685	Mäkelä, Aarne; Kotilainen, Kaija	On the water-solubility of plant minerals	1967	17	.pdf	application/pdf	8367	490	69	Calcium sulphate is common in the sap of the cell (water solubility 0.2 %) whereas gypsum crystals are seldom encountered (Baumeister 1958, p. 517). Even such a difficultly soluble Ca- compound as CaS0 4 (water solubility 0.2 %) occurs in plants in water-soluble form with the exception of a few rare cases.	cache/afs-71685.pdf	txt/afs-71685.txt
