Description :
The aim of this study was to analyze the impact of exclosures on soil fertility restoration and examine its variability across age, agro-ecology and landscape position. The study was conducted in the Gubalafto district of North Wello Zone, northern Ethiopian highlands. Vegetation cover was estimated and soil samples were collected from 3 age categories (open sites, 10- and 27-year-old exclosures), 2 agro-ecological zones (mild and cool) and in 3 landscape positions (lower, mid and upper). The samples were analyzed for selected soil physico-chemical properties using standard laboratory procedures. The results were statistically tested using analysis of variance (ANOVA). The results suggest that exclosure implementation and utilization planning should consider soil fertility restoration variation with age, agro-ecology and management conditions of the respective exclosure.
