It was observed that soil infiltration rate decreases not only with increasing sprinkler application rate, but also with increasing soil gypsum content. Additionally, the soil infiltration rate decreased rapidly following the first irrigation, and then declined with the successive seven irrigation events. Smaller range (d < 4 mm) of drop sizes range was conjugated with high application rate sprinkler (R3000 red-plate sprinkler), while the wider range (up to 5.5 mm) of drop sizes was produced by the low application rate sprinkler (R3000 orange-plate sprinkler). The high values sprinkler power of the R3000 red-plate sprinkler droplets reflects the actual kinetic energy transferred to the soil surface which resulted in a considerable reduction of infiltration rate for all the studied gypsifereous soils.
