Soil Fertility Status as Influenced by Slope Gradient and Land Use Types in Southern Ethiopia

Table 4

Interaction effect of land use and slope gradient on selected chemical properties of soils at Azit subwatershed.

Soil property	Land use	Slope gradient			LSD (0.05)	CV (%)
		US	MS	LS
		10–15%	5–10%	2–5%
OC	Cultivated	1.50^a	1.67^ac	2.77^a	0.20	5.30
	Grazing	2.43^b	2.50^b	2.73^a
	Eucalyptus	1.63^ac	1.73^c	2.40^b

Means within columns followed by the same letter are not significantly different from each other at . CV = coefficient of variance, LSD = list significant difference, OC = organic carbon, US = upper slope, MS = middle slope, LS = lower slope.
