Extract

1. Palestine Pan, “Nasas”, is found in the coastal plain among red sandy soils and its presence is shown by one or more impermeable layers in the depth.

2. Red sandy soil in which “Nasas” is present is an unstable soil system which is liable to the process of degradation.

3. Observations made on red sandy soil in relation to relief show the transportation of colloidal clay, A1(OH)3 and Fe(OH)3, along the slope and into the depth.

4. The ratio of A1(OH)3 to Fe(OH)3 shows a relatively large downward transportation of A1(OH)3. This increase of A1(OH)3 in the lower layers of the soil is the chief factor in the formation of the impermeable layers.
