Willingness to pay for excreta pellet fertilizer: Empirical evidence from Ghana

JOHN K. M. Kuwornu, Alfred B. Narh JNR, Irene S. Egyir, Edvard E. Onumah, Solomie Gebrezgabher


This study examined farmers’ willingness to pay for excreta pellet fertilizer in Ghana. Primary data was obtained from 461 farmers in 10 districts in the Western and Greater Accra regions of Ghana through randomized questionnaire administration. The contingent valuation method was used in eliciting the farmers’ willingness to pay decisions (WTP) and maximum amount they are willing to pay. The Tobit regression model results revealed that being a household head, unit cost of current fertilizer used, and farm size positively influenced the willingness to pay amount whereas previous use of organic fertilizer influenced the willingness to pay amount negatively.
