Field tests were conducted to obtain irrigation evaluation and solute transport data. The data were used to calibrate and validate an advection-dispersion model for furrow irrigation. The empirical infiltration equation and roughness parameters were

A cross-section-averaged advection-dispersion equation ADE model was developed to simulate the transport of fertilizer in furrow irrigation. The advection and dispersion processes were solved separately at each time step by implementing a method of c

Fertigation using surface irrigation is a cost-effective and simple method of applying fertilizer across the field. The primary objective of this study was to compare different strategies for timing injection of bromide and its fate when injected int
