Aiming to study effects of soil depth and rivers slop on total boron concentration in Middle Euphrates River Reion that represent in the sedimentary plain, soil pedon samples of cultivated territory that adjacent to rivers were taken. These regions are located in provinces of Karbala, Babylon, Najaf, Diwaniyah, and Al-Muthana. Ten soil pedon were taken of soils that adjacent to the main Euphrates River, the Al-Hilaa, and the AL-Daghara Rivers in these provinces. Soil pedon of soils that on the banks or close to the main Euphrates River were taken of counties of Twarije, Kufa, Gamas, and Al-Samawa. In the same way, soil pedon of Missaib, Hashmiah, Diwaniyah, and Rumitha are adjacent to the Hilla River and soil pedon of Al-Daghara and Affak belongs to the area of Al-Daghara River. Results show a reduction in total boron concentration for all of the tested soil pedon directly related with the depth. Aggregate boron concentration values are the highest at the surface layer and reduce as going depth except for soils of Al-Samawa and Al-Rumitha. Total boron concentration values are fluctuated between 1.033 mg. kg-1 and 14.658 mg. kg-1 in all of the studied soils. the results showed too the total boron values are not conducted with the tourmaline mineral percent in all sites..

A field experiment is carried out in a private farmer's farm located in AL-Qadisiyah/ Diwaniyah/ Daghara/ Sadr Al-Daghara area to study the effect of organic and mineral fertilizers on dissolved potassium values inside and outside Zea maize rhizosphere. The randomized complete block design (RCBD) is designed in three replicates with two factors: the first is factor with four levels of potassium sulphate which are (0, 75, 150, 225) kg K. ha-1 symbolized by the symbols (K0, K1, K2, K3) respectively, and the second factor with four levels of organic matter (poultry residues) which are (0, 10, 20, 30) tons. ha-1 symbolized by the symbols (O0, O1, O2, O3) respectively. The seeds of Zea maize (Zea mays L.) are cultivated in the form of lines (DKC 6120) 20/7/2016.
The results show that the addition of potassium sulphate in different levels has achieved a significant increase in the amount of soluble potassium inside and outside the soil of the root zone and for all time periods (40,70,100) days of planting and the mineral fertilizer has exceeded the organic fertilizer in increasing the amount of soluble potassium and the interaction between the highest level of potassium fertilizer 225 kg k. ha-1 and the highest level of organic fertilizer 30 tons. ha-1 (K3O3) achieves the highest amount of soluble potassium within the root zone which amounted to (0.131,0.163) cmol.kg soil-1 respectively, and (0.179,0.167) cmol.kg soil-1 outside the root zone respectively for the periods (40,70) days of planting respectively, while after 100 days of planting the interaction (K2O3‌) achieved the highest amount of soluble potassium which is amounted to 0.114 cmol.kg soil-1 inside the root zone and the interaction (K3O3) achieves the highest amount of soluble potassium which is amounted to 0.159 cmol.kg soil-1 outside the root zone and a decrease in the amount of soluble potassium in all treatments is noticed with the increase of plant growth time.

In order to investigate the role corn cobs and gypsum in some physical characters and organic matter of clayey cracks and their properties. Seven soils sites (Afak, Al-Diwaniyah, Al-Taleea, Babel, Agriculture college, Al-Wahda and Al-Raid project)
There are three types of treatments as follows:
- Corn cobs was applied in four levels (0 . 10 . 20 and 40) g.kg-1
- Gypsum (calcium sulfate) applied in four levels (0 , 5 , 7.5 and 10) g.kg-1.
- Treatments of interaction between corn cobs and gypsum.
Corn cobs , gypsum and their interaction were applied in same levels above.
In this experiment , 2 kg of each studied soil were treated with same levels of corn cobs and gypsum above and incubated at 30 + 2 °C for 90 days and 80% relative moisture content at 33 kpa. The results were summarized as :
Soil aggregate stability (MWD) and organic matter values were increased , while modules of rupture and (COLE) values were decreased , with increasing of gypsum and corn cobs applying. Also, results showed that the decreasing of (COLE) values were depending on the clay content and interaction treatments , between corn cobs and gypsum. The decreasing of (COLE) values were the highest in the clayey cracks disappeared treatments.

To study role of gypsum and corn cobs in linkage of fractions in cracking soils. Three soils (Al-Diwaniya , Al-Wihda and college of Agriculture / Abu Ghraib) were chosen for this study . They were treated with two levels of gypsum (0.5 and 1) % with one level (4%) of corn cobs . In this experiment , 2 kg of each studied soil were treated with same levels of corn cobs and gypsum above and incubated at 30 + 2 °C for 90 days and 80% relative moisture content at 33 kpa. And then the soils were sieved with 1 mm sieve to measured the x-ray diffractions . The results showed :
The intensity of clay minerals peaks which treated with gypsum and corn cobs were decreased comparing with control sample. We believed that the gypsum should be facculated on clay minerals surfaces and mask them to appear clearly , and suggested that the gypsum was played an important role in conjugated of soil particles. Results of X-ray diffractions showed that there was no evidence of interaction between organic matter (corn cobs) and clay mineral inter layers.
