Fertilizer Nutrient Costs

AFFIRM fertilizer recommendations are based on expected yield responses of crops from research results and an economic analysis of marginal fertilizer cost to marginal yield returns. To make this economic analysis AFFIRM requires estimates of crop nutrient costs in $ per lb (Figure 7.2.5). A calculator is built into AFFIRM to calculate individual crop nutrient costs based on the cost per tonne of individual fertilizers.
