This paper reports on a bioeconomic modeling exercise that analyzes the dynamic effects of fertilizer use and employs the results to answer fertilizer policy questions. Using data from the Senegalese Peanut Basin, the model (1) simulates yield and soil nutrient impacts of selected cropping practices, and (2) integrates the simulated yield and soil nutrient outcomes into a multi-period linear programming model (LPM) that takes into account current and future input/output prices, and farm household resources and objectives. The model results are used to address two important questions facing Senegalese policymakers: (1) Are recent price, credit and capital transfer policies in Senegal likely to encourage farmers to increase fertilizer use over time? And (2) Will the optimal cropping practices identified by the LPM have a positive impact on the soil macro-nutrient stocks of N and P as well as on farm income?
