A study was conducted in the laboratories of Soil and Water Resources Department, College of Agriculture ,University of Anbar in the Fall season of 2011-2012 to prepare compost from some organic waste (mixtures of ground wheat straw and chicken wastes) of 30:1 and 40:1 C:N ratio enriched with 0.46% P by weight from either calcinated or raw of phosphate rock and inoculated with one of microbes solubilizing phosphate as that Pseudomonas fluorescence or Bacillus pumilus or Aspergills niger. All these combined materials exposed to the composting process for one month with adequate temperature, moisture and mixing intervals to from bio-organic fertilizer and to make some evaluation of the product.
The results showed that the combination of organic wastes of 30:1 C:N enriched with raw phosphate rock inoculated with P. fluorescence gave the highest percent of fulvic and humic acids at the end of composting process which were 11.7% and 12.36% respectively and the highest microbial density (2.037*106cfu.g-1).However, the combination of organic waste of 30:1 C:N enriched with calcinated phosphate rock and inoculated with P. fluorescence gave the highest available P.

This study was conducted at college of Agriculture – university of Anbar during fall season 2010 to study possibility of using some organic wastes and mineral materials in treatment of saline soils and it application in irrigation. This study including laboratory experiment which design to determine the best treatment of saline water by using different plant organic wastes and mineral materials (calcite and gypsum). Four sources of plant organic wastes which included: shimblan plant, cob of corn, wheat straw, sunflower steems for the total decomposition. All organic wastes were mixed with the mineral materials (20% calcite and gypsum). Saline water was added with dilution ratio of 1:10 , 1:20 , 1:30 , 1:40 and 1:50. The EC , pH and SAR at the extract were measured. Results of this studded showed

1. The best contribution of organic wastes in decreasing value of EC of saline water were by cob of corn and wheat straw while sunflower steems and shimblan showed no contribution in this respect under the conditions of this study.
2.Using organic wastes resulted in decrease in pH values in all treatments.
3. SAR values were different with different types of organic wastes the rating of decline were cob of corn, wheat straw, sunflower steem and shimblan.

Two genuses of imported nuts (Turkish Hazelnut and Uzbek Walnut) were examined for their nutritional and mineral contents. It was found that the percentages on dry weight basis of total ash, proteins, lipids, total carbohydrates, reducing sugars, crude fiber, total phenolic compounds, free phenolic compounds, tannins(g/100g) and ascorbic acid (mg/100g) for the hazelnut were 1.92, 14.45, 56.22, 15.89, 3.84, 7.90, 9.57, 9.57, 0.00 and 5.80 respectively, and for the walnut were 1.85, 14.28, 61.72, 12.94, 2.96, 5.85, 9.23, 9.23, 0.00 and 1.12 respectively. The minerals Ca. K and Na were determined using Eppendrof flame photometer and the recorded values for the Hazelnut were 1375.50, 6122.90 and 34.90 µg/g respectively, and for the walnut were 825.00, 5220,00 and 18.80 µg/g, respectively. A colorimetric method was used for determining phosphorus using ammonium-vandate-molybdate as indicator and the values for hazelnut and walnut were 3260.00 and 4000.00 µg/g, respectively. The minerals Mg, Mn, Fe, Zn, Cu, Co ,S, I, Cr and Se were determined using atomic absorption spectrophotometer and were found to be 1763.60,59.30, 38.80, 23.90, 16.72, 0.11, 0.40, 0.00, 0.28 and 0.03 µg/g for the Hazelnut, respectively , and for the Walnut were 1580.00 , 28.50, 26.42, 25.50, 13.10, 3.11, 0.38, , 0.23, 0.00 and 0.04 µg/g, respectively .The Minerals Ni, Cd and Pb were found as trace elements gave amounts less than 0.03 µg/g.

The presence of high concentration of cadmium (Cd) in the by-product treated wastewater of phosphate industry in west of IRAQ caused real heavy metal pollution for soil, water resources, and crops in the area. Accordingly, the aim of this study is to evaluate the effective method to reduce cadmium concentration of treated wastewater. Four locally available materials namely rock phosphate, bentonite clay, lime and silicate rocks were evaluated as cadmium adsorbing agents. Effect of weight and piratical size in Cd adsorption capacity of each material were also evaluated.
Results showed that adsorption capacity of the tested materials in the following order: rock phosphate> bentonite clay> lime> silicate rocks. Results also showed that the that the best size making higher adsorbing is < 0.1 mm, then 0.1 – 0.5 mm and then 0.5 – 1.0 mm. Also, the amount of Cd adsorbed by each material increase with the increase of weight of adsorbing material added per unit of wastewater. Amount of Cd adsorbed in relation to weigh of material added is in the following order: 0.5 gm > 0.25 gm > 0.1gm. While the adsorbing decrease with the increase of material particle size. Also First order equation was the best fit equation which is described the adsorption of cadmium in four tested materials, particles size and weights of materials added.

An experiment was carried out in the lath house, department of Horticulture, Collage of Agriculture, University of Baghdad, from April 2002 through July out 2003 . This investigation aimed to study the effect of irrigation with saline water, soil texture , and soil moisture content on leaf concentration of N, P, K, Ca, Mg, Cl, Na, of sour orange seedlings.
Three levels of water salinity, (2, 4 and 6 ds.m-1 ) were used by adding NaCl, CaCl2 and MgCl2 at ratios 1:1:1 to well water with salinity of 2 ds.m-1. Irrigation operation was performed after loosing 25 and 75% of available soil water which is squeezed between (330 and 1500 KPa) with additional 15% of water as leaching requirements. Seedlings planted in polyethylene sacks after filling with 20 kg soil (two different texture sandy loam soil and silt clay loam).A factorial experiment with a Randomized Complete Block Design (RCBD) was adapted.The results showed that seedlings grown in sandy loam soil, irrigated with saline water by 2 ds.m-1 after loosing 25% from available water showed the optimum values of leaf content from N, P, K, Ca, Mg and minimum of Na,Cl.
