Extent, Distribution, and Causes of Soil Acidity under Subsistence Farming System and Lime Recommendation: The Case in Wolaita, Southern Ethiopia

Table 5

Field position and cropping intensity effects on the mean value of soil pH (N = 789).

Field position	pH	Cropping intensity	pH
H	6.77a (104)	One	6.31a (254)
M	6.37b (119)	Two	6.06b (395)
D	5.93c (566)	—	—
value	0.0005	value	0.0001
CV (%)	9.2	CV (%)	10.3

H = homestead field, M = middle field, D = distant field; Note: numbers in the bracket refer to sample size.  < 0.001. Means in a column followed by the same letters are not significantly different at 5% level of significance; CV = coefficient of variation.
