    Notes: Abstract The von Liebig, Cobb-Douglas, and Quadratic functions were evaluated using Generalized Least Squares on fertilizer response data for crops grown in Ghana and Mali. This was done to determine which model is most likely to overestimate fertilizer use. Model fit varied for crops and soil types. The von Liebig was slightly superior, based on prediction criteria and number of significant variables. The von Liebig functional form also produced the most conservative optimum yield estimates and input levels, while the Cobb-Douglas was most likely to overestimate yield and hence input use, but produced the highest net returns for cotton.
