Adoption and impact of fertiliser trees on heterogeneous farmer classified soil types in the Chongwe district of Zambia

ABSTRACTAdoption of fertiliser trees in Zambia remains very low while efforts to understand the farmers’ decision-making process in embracing sustainable agricultural practices still eludes research. One area not vigorously pursued in understanding the farmers’ adoption process is the role that farmer classification of on-farm soils plays in adoption and impact of sustainable technologies such as the fertiliser trees. Therefore, the objective of this study was to estimate adoption rates and impact of fertiliser trees on heterogeneous soil types according to farmers’ classifications. Using data randomly collected from 324 households in the 2011 farming season in Chongwe district of Zambia, it was found that farmers were able to classify the dominant soils on their farms into sandy, clay, sand loamy and loamy soils. Most of the farmers (60%) who perceived their soils to be sandy also indicated facing soil fertility challenges. Perception of being on sandy soils was significantly associated with adoption of ...
