Abstract
The present study concerned with physical and chemical properties of water, sediments and soils for many locations of Thi-Qar marshes during July-August (2004). pH, conductivity, total hardness, turbidity, ions concentration of Cl-, Ca++, Mg++, K+, Na+, HCO3- for water were estimated the results were as follow: (7.4-7.8), (1.22-12.25 mmohs/cm), (211.2-2475) mg/l, (3.8-28.0) mg/l, (67.2-943) mg/l, (57.6-530.1) mg/l, (14.88-461.6) mg/l, (0.7-11.9) mg/l, (140-655) mg/l, and (3.3-1.6) mg/l respectively. The bulk density, particle density, total organic carbon (TOC %), soil texture, pH conductivity and ions concentration of Cl-, Ca++, Mg++, K+, Na+, HCO3-, the percentage of (NH4+) for sediments were measured. The results were as follow: (1.04-1.25) g/cm3, (2.35-2.70) gm/cm3, (0.62-0.85%), silty loam, sandy loam, clay loam, (7.6-7.8), (3-8.2) mmho/cm, (171.5-686.2) mg/l, (172.8-403.4) mg/l, (39.6-430.4) mg/l, (2-8.9) mg/l, (575-855) mg/l, (6.12-9.3) mg/l, (0.05-0.08%) respectively. The bulk density, the particle density, total organic matter, texture, pH, conductivity, ions Cl-, Ca++, Mg++, K+, Na+, HCO3-, NH4+ % for soils were measured. The results obtained were as follow: (1.05-1.25 g/cm3), (2.4-2.6 g/cm3), (0.98-1.54 %), sandy loam, silty loam, silty loam, silty loam, (7.4-7.8), (7.2–9) mmhos/cm, (171.5-345.6 mg/l), (288–518.4 mg/l), (140.5–408.9 mg/ l), (4-6.7 mg/l ), (600-745 mg/l), (6.12-9.3 mg/l), (0.03-0.07 %) respectively. The study revealed that the water in the most of marsh's sediment and soil was of high salinities and in high dangerous of Na+, but may use for the waterly-life.
