2017-2-3  The decrease in evaporation from the sandy loam part occurred in two steps in this example. The first gradual decrease occurred as the surface of the sandy loam was dried out and the residual water content was reached (Figure 6). During this time, the finer silt material continued to evaporate at a high rate and did not dry out.
