الملخص EN

The study was carried out at Soil Research Center in the province of Daraa during 2011 in order to study some physical and moisture characteristics for cinnamon soil, which occupies (48000 km²), equivalent to 26% of the area of the Syrian Arab Republic and represents the cultivation of growing field crops with a rainfall ranges between 150- 300 mm.

The results showed that the mechanical analysis for soil referred that its texture is clay with a good ability to retain water, the field capacity rated between (30-38.85)%.

The studied soil has high value of available water (38.93mm) and useful water (25.69mm) in the surface layer.

The highest value of permanent wilting point and hygroscopic moisture was reached in the final depth in studied profile soil, It was also distinguished a high total porosity ranged between 51.78 and 55.59% with a good air porosity amounted to 9.38 - 15.47 % in different depths and with the decline to 5.51 % in the depth 30 - 45cm.
