The study uses interval regression to investigate factors affecting farmers’ willingness to pay for soil testing services in Northern Haiti. The model reveals that factors such as the type of crops grown, group membership, farmers’ educational level, access to credit, gender, contact with extension services or any institution, type of soils, income level, participation in soil testing program and farm size affect the amount to be paid for soil testing services. These results imply that the training module on soil testing and financial support in form of subsidies or access to credit should be provided to farmers.
