ABSTRACT
ABSTRACT: Furrow fertigation can be an advantageous practice over traditional methods for fertilizer application. Fertigation efficiency and uniformity are tightly related to irrigation water efficiency and uniformity. This work presents a simulation model of furrow fertigation that was calibrated and validated with experimental data. The model predicts water flow and solute transport throughout Saint-Venant and advection-dispersion equations. Values for the three semi-empirical parameters of the model were obtained through a calibration process. The model can reproduce water advance times, flow depths and fertilizer hydrodynamics adequately, particularly for medium and large irrigation discharges.
