Table 8

Main effects of land use and soil depth on some chemical properties of the soils.

Land use types	pH (H2O)	EC (ms/cm)	OM (%)	TN (%)	Av. P (mg/kg)	Ex. K (cmolc/kg)	CEC (cmolc/kg)
Natural forest	6.5^a	0.10^a	11.0^a	0.32^a	10.1^a	2.2	40.4
Eucalyptus plantation	6.0^b	0.06^b	4.4^b	0.18^b	5.9^b	1.8	39.7
Grazing	6.4^a	0.04^c	2.5^c	0.11^c	4.9^b	1.2	37.2
Cultivated	6.5^a	0.02^d	0.8^d	0.06^d	7.6^ab	1.5	38.1
LSD (0.05)	0.21	0.01	1.02	0.04	3.45	NS	2.60
CV (%)	2.7	19.2	17.5	18.2	38.9	33.6	5.4
Soil depth
0–20 cm	6.3	0.07^a	5.6^a	0.18^a	7.5	1.7	38.9
20–40 cm	6.4	0.04^b	3.8^b	0.15^b	6.8	1.6	38.8
LSD (0.05)	NS	0.01	0.72	0.03	NS	NS	NS
CV (%)	2.7	19.2	17.5	18.2	38.9	33.6	5.4

The main effect means within a column followed by the same letter are not significantly different from each other at . NS = not significant; CV = coefficient of variation; LSD = least significant difference.
