Abstract
This study was set to examine factors influencing agroforestry upscaling, inter-plot natural fertilizer transfer and inter-plot income flow in Arsamma watershed. A semi-structured questionnaire was used to gather necessary information. Contingency table, chi-square, Phi and Cramer's V were used to analyze the data. Access to seedlings was the most important determinant of agroforestry upscaling; and farmers' production orientation, farm size and wealth status ranked, respectively, second, third and fourth. Inter-plot natural fertilizer transfer was primarily influenced by participation in agricultural extension. Wealth status and livestock size ranked, respectively, second and third in influencing inter-plot natural fertilizer transfer. The study indicated a geographic concept of spatial land-use integration for soil fertility management and key factors influencing agroforestry-based land-use integration. Agroforestry-centered diversified small-scale agricultural commercialization, tree-crop-livestock integration, agricultural extension services promotion and multi-purpose tree species supply are the way out to upscale agroforestry and agroforestry-based spatial land-use integration.
