Cartographic representation of Soil physical properties In Habbaniyah District using Geomatics techniques

Abstract

This research deals with the cartographic representation of the physical properties of the soil in the Habbaniyah district by employing (Geomatics) techniques, and the study was carried out by the researcher collecting (23) surface soil samples at a depth of (0-30) cm, distributed over the district area, determined by relying on a device. GPS, And then have been conducted laboratory analyzes in order to obtain the physical properties of soil data were dropped coordinates and the results of analyzes on the map pattern of area study is not the product of maps of the spatial distribution of the physical properties of soil, it has been the process of spatial analyzes process  depending on the spatial program (Arc Map 10.5). The show of the study that the highest percentage of sand in the area of the study amounted to (94%) within Al-mlahmh Province The highest rate for the silt was among the provinces Ghazwan and Al-Hamamiyat and Krtan part of Husaybah al-Sharqiyah by (62%) The percentage of the clay has reached the highest percentage of his (20.4%) in the southwest of Haswah al-Shamiya district, south of the study area, and it was found that there is little variation in the values ​​of bulk density in the soils of the study area, as it reached its highest value.(1.716g/cm ^-3) in the southeast of Haswah al-Shamiyah district, while its lowest value was ( 1.188Gm / cm ^-3) In the southwest of Haswah al-Shamiya, which is the largest district of the Habbaniyah district by area, the actual density values ​​are close, as the general average reached (2.520 g / cm ^-3), while the average percentage of porosity in the soils of the study area was (41.698%).
