Agro-ecology, resource endowment and indigenous knowledge interactions modulate soil fertility in mixed farming systems in central and western Ethiopia
Siteâ€specific soil fertility management requires a fundamental understanding of factors that modulate soil fertility variability in the local context. To verify this assumption, this study hypothesized that soil fertility variability across two regions in Central and Western Ethiopia is determined by interâ€related effects of agroâ€ecological zones and farmers’ resource endowment (‘wealthy’ versus ‘poor’ farmers).
