Abstract
The study was carried out to detection the characteristics of the soil units in the fields college in Al- Rasheedyia region to reach well management for these soils , as well as this study consist a basic of data for all studies carried out in this location especially in plant production . Detailed survey have been done for these soils, two sites were chosen to representative the soils, then two profiles dugs .The results shows that these soils are recent and weak development , the profile characterized that is from the kind of AC horizon and formed from recent sediment . the texture characterized that loamy in profile 1 and silty loam in profile 2. Sand range from 267.2 – 567.7 gm. Kgm-1 , silt range between 342.5 – 589.5 gm. Kgm-1 ,were the clay range between 89.8 – 241.3 gm. Kgm-1 . Bulk density shows high value , especially the surface soils ,this reverse bad management . Organic matter regarded enough and decreasing with depth ,and range between 21.0 – 5.1 gm . kgm-1 . Electric conductivity value is relatively high, and range from 3.380 – 6.640 Ds . m-1 . Nitrogen is found with enough amount, whereas phosphorus found in very little amount, calcium & magnesium shows relatively high content but with reversible behavior . Sodium content is the higher between the other soluble cations and range between 228 – 772 Me . L-1 .Sulphate exhibit higher content between the other anions and range from 285 to 550 Me. L-1. these soils are classified according to U.S.Soil classification system ( 7th approximation ) in Entisols order , also most of these soils classified in class І in land capability classes ,few part of these soils put under class П .
