Soil Management Knowledge Transfer in Tanzania’s Southern Agricultural Growth Corridor: Actors, Methods and Challenges

Abstract

Soil management technology is essential for sustainable agricultural production systems, social and economic development for farmers. This paper follows an ethnographic research method to investigate soil management technology knowledge among actors in the southern agriculture growth corridor in Mbeya. The key informant interview,52 in-depth Interview, 2 focus group discussions, and observation data collection methods were used, and a thematic data analysis technique was employed to analyze data to understand the knowledge dynamic in agriculture. The study found that farmers use agroecology soil management technology (mulch application, planting of trees to add fertility and reduce erosion, crop rotation, intercropping, manure application, leaving crop and house/kitchen waste, minimal tillage), conventional soil management technology (soil testing, use of fertilizer and lime) and mix of the two. The study area used demonstration plots, farmer field school, training, agriculture shows, farm and home visits, mass media, and farmers' field days. knowledge is transmitted by farmers, researchers, and extension agents from both the government and private sectors all these method makes adoption easier and faster for farmers. The study recommends increase in efforts to promote relevant soil management practices to the targeted groups in a coordinated way. Extension agents should capitalize on the farmers-to-farmer learning approach by creating e-lead farmers, empowering them, and closely working with them.
