Effects of lime on soil basic cations and CEC (mean).

Lime rate (t/ha)	Ca	Mg	K	Na	CEC
	cmol (+)/kg soil

LSD 0.05	5.19	3.05	2.64	2.77	1.9
CV %	0.12	2.38	0.44	3.58	5.99

LSD 0.05: least significant difference at the 5% level; CV: coefficient of variation. Means in a column followed by the same letters are not significantly different at the 5% level of significance.
