Input-scaled sorghum biomass C and N₂O emissions.

<p>Simulation results for input scaled biomass C (panels a and b) and nitrous oxide emissions (c and d) for sorghum grown under current and future climate. Open symbols are for simulations at 8.4 g N ∙ m^-2, closed symbols represent 17.3 g N ∙ m^-2 fertilizer rates. Scaling is accomplished by considering fertilizer mass (g N ∙ m^-2) and irrigation (mm H₂O) used to produce a given unit of aboveground biomass or nitrous oxide. Scaling equation detailed in methods, points above or below dashed zero line represent increase or decrease in biomass or emissions due to fertilization or irrigation. Points are mean value and error bars are SEM for current weather simulations (a and c) or the range of simulation values across a suite of future weather inputs (b and d).
