2.4. Data processing and analysis
Data collected was subjected to descriptive analysis of simple proportions using the SPSS Version 12 statistics software. The main tools of analysis were descriptive statistics including frequency distribution for all variables. Uniformity between respondents in the different communities was determined using two-way Chi-square ( χ2) test of homogeneity analysis (Gomez and Gomez, 1984). Statistical significant differences in soil physico-chemical properties between fertile andinfertile plots were analyzed using one-way analysis of variance (ANOVA). The assumption of normality was assessed using Shapiro– Wilk tests. Where the tests indicated significant differences among land-use types, means were contrasted with post-hoc Tukey HSD tests at pb 0.05. All the analyses were done using a statistical software package (Statistix 8.0., 2001 ).
