“…From related literature, evidence on farmers' soil management decisions suggests many farmer characteristics of interest in this study (Waithaka et al, 2007;Shiferaw et al, 2009;Parvan, 2011;Chikowo et al, 2014;Borges et al, 2015;Abebe and Debebe, 2019;Mellon-Badi et al, 2020). Kassie et al (2013) group these factors into: 1) farmer characteristics, including age, gender, educational attainment in the household, participation in non-farm work, organic fertiliser experience and risk attitude score, 2) social capital factors, including contact with extension agents, farmers' group membership, access to organic fertiliser policy and training opportunities, and 3) physical resource characteristics such as livestock, carting equipment, plot size and total landholding.…”
