Summary

Exact equations to predict the leached fraction of fertilizer applied at the soil surface with irrigation water have been derived from solutions of the equation of hydrodynamic dispersion. These exact equations are compared with an approximate equation derived by Pandey (1979) for the same problem; his equation sometimes gives rise to considerable errors.
