The values plotted in green are estimated responses to lime treatments, where the additional yield (relative to yield with zero lime) is plotted on the y-axis and the amount of lime is plotted on the x-axis. Use the sliders to adjust the assumed farmgate maize and lime prices and observe how the profitability of the lime investments change in response. The goal is to explore how positive agronomic responses to lime may or may not actually be profitable for a farmer.
