Determinants of integrated soil fertility management technologies adoption by smallholder farmers in the Chinyanja Triangle of Southern Africa
Integrated Soil Fertility Management (ISFM) technologies have proven to be viable options for improving land productivity and increasing yield. However, adoption of the set of complementary technologies that are required in ISFM is quite variable and studies of adoption focus on single technologies. This study of 10 technologies shows that farmers in Chinyanja Triangle use up to eight and cluster analysis revealed 3 groups. The clustering of nutrient dense technologies of inorganic fertiliser, compost and animal manure indicates that they are used by farmers facing similar constraints. Analysis of the determinants of adopting more than one ISFM technology using a pooled and random effects ordered probit model shows that farmers' adopting a set of technologies have fragmented pieces of land, more literate household members, more farming experience, headed by males. Non-adoption has been associated with ownership of large parcels of land and large family sizes. These results are instrumental in identifying factors that influence adoption of a set of ISFM technologies in the Chinyanja triangle and could be of use in research and development initiatives.
