Diagnostics and Characterization of Micro morphological Features of some Soil Series in Baiji City, Central Iraq

Three pedons were selected representing the soil series of study area in Baiji city, which are Khadraniya, Al-Sharqat, and Manjour soils series, calcareous gypsiferous soils, to diagnose some micro-morphological Features horizons. Pedons morphologically described, disturbed undisturbed samples collected from each horizon. The presence (calcic) (gypsic) horizons has been diagnostic by morphological field results, ccumulation lime gypsum matrix as vertical gypsic threads beards aggregates under gravel crystals size coarse sand, well nodules intertwined within structure units that reflects influence parent material primary sedimentation sources .The results characteristics represented distinct shapes, including lenticular, spindle Enhedral subhedral, fine granules filling pores, pores vughs chamber, spongy granular structure, iron coating form Encases crystals.
