afs-5673	ERSTAD, K.-J.; KONOVALOV, N.Y.; PUTRO, J.	Reactivity of silicate liming materials from Northern Europe assessed by Soil Incubation and two pH Stat methods	2000	16	.pdf	application/pdf	8778	462	68	The method was an automatic potentiometric titration, where each sample of liming material was leached for 24 hours in a water suspension, while pH was constantly kept at 5.0 by adding 0.4 M nitric acid (HNO 3 ) into the titration vessel, as soon as the pH of the solution tended to rise. The pro- cedure SUMMARY was used to calculate the conversion factors (convf n ) fraction by fraction applying different methods to determine the re- activity of liming materials.	cache/afs-5673.pdf	txt/afs-5673.txt
