This study included different soil locations around Mosul city representing non salt affected soils, and around Basrah city representing salt – affected soil. The aim of this study is to show the behavior of sodium due to first order and diffusion equations, using miscible displacement at different times (10, 20, 30, 60, 90, 120, 180, 360, 480, 600, 720 minute). The results indicate that the solubility and release of sodium decreases with time, but according to kinetic concept the cumulative of sodium solubility increased in the two type of soils study. However, salt affected soils showed more solubility and release of sodium than the non-salt affected soils.  While the diffusion equation gave the best description of sodium solubility depending on the coefficient determination and standard error. Selectivity coefficient of Gapon due to the chemical concept KG, thermodynamic concept KG-  and sposito concept KG= were also examend which showed that the values KG , KG-  decreased with time , while KG= values increased over time.

A antioxidant activities of red sumac fruits (semi ripe) (Rhus coriaria) extracts were evaluated and compared with Butylated Hydroxy Toluene (BHT) as a positive control compared sample by using reducing power test, B-Carotene bleaching test, Hydrogen peroxide scavenging activity test and FTC (Ferric thiocyanate) assay. Red sumac fruits were extracted with different solvents (methanol, ethanol, aceton, diethyl ether, ethyle acetate and hexan). The properties of extraction solvents significantly affected extraction yield ,total phenolic compounds and antioxidant activity of red sumac extract, methanol(80%) gave highest extracted yield from red sumac fruits. Also methanolic extract showed highest content of total phenolic compounds compared with other extraction solvents used in study. The methanolic cude extract of red sumac fruits had better antioxidant activity compared with samples treated with extracts by other extraction solvents. The antioxidant activities could be arranged as follow :BHT

Soil salinity is one of the most serious limiting factors that affect plant growth and productivity of various crops in arid regions. Methods commonly used to combat salinity are either classical or new using halophytes.This study was conducted at plastichouse in order to evaluate the efficiency of Atriplexhalimus in salt removal from saline, saline-sodic soils of Al-jazeera project in Ninavah province. Plantation with A.halimus decreased electrical conductivity for saline- sodic soil from 39.2 to 26.5dS.m-1 and from 6.2 to 4.9 dS.m-1 for saline soil. Sodium adsorption ratio declined to half and 28.6% for saline- sodic and saline soils respectively. The current study revealed an increased efficiency of Atriplexhalimus with increasing salinity which suggest it a good candidate for soil desalination in arid and semiarid regions.
