Abstract. Urmia Lake located in the north-west of Iran, is one of the largest hyper-saline lakes in the world. In recent years, most of the Urmia Lake have been rendered to unusable lands. Drought and rapid increase in agricultural activities are the most important reasons behind the shrinkage of the Lake. This kind of exploitation with the added salinity from irrigation occurring over time has caused increased soil salinity in the basin leading up to desertification. Soil salinity research are crucial to understand underlying causes and consequences of the drying Urmia Lake. In this study, we use remote sensing technology and image processing techniques to detect spatio-temporal variability of salt body, salt affected lands, and development of irrigated lands to estimate the extend of salinization in terms of spectral response of satellite images for the Urmia Lake Basin from 1975 to 2016. The results of this study indicate that salt and salty soil areas has increased dramatically from 1995 to 2014 and more than 5000 km2 of Urmia Lake's water surface area was converted to salt or salty soil bodies during recent years. Salinization and desertification progress are not limited to just dried bottom of the Urmia Lake. Although the area of irrigated lands has increased more than two times during the studied period, soil salinity has increased in regions close to Urmia Lake too. This desertification in the basin have potential to be the source of dust storms, which have adverse effects on people's life and climate as well.

Nutritive value of Sesbania aculeata hay was determined by estimating the nutritive components, nitrogen forms, in vitro digestible organic matter (IVDOM), and metabolisable energy (ME). A study was carried out to evaluate the effect of feeding 2 groups of Syrian Awassi ewes with 2 wheat straw-concentrate diets without (control) or with (experimental) added S. aculeata hay on some reproductive parameters of the ewes at different stages. Half of the wheat straw in the daily ration of the experimental group of ewes was replaced by S. aculeata hay (whole plant) grown on salty soil and irrigated by saline water. Daily metabolisable energy and crude protein consumed by the ewes in the 2 groups were the same during the different stages (2.5 months before mating, throughout pregnancy, and during lactation). Crude fibre and cell wall constituents’ values were lower, whereas the values of crude protein and crude ash were higher in leaves and pods than in stalks. The values of IVDOM in S. aculeata hay were 537, 380, and 626 g/kg DM, and of ME were 7.19, 5.43, and 8.58 MJ/kg DM for the whole plant, stalks, and leaves and pods, respectively. The values of buffer soluble nitrogen were 27% or 39% and of buffer soluble non-protein nitrogen were 21% or 35% of the total nitrogen in leaves and pods or stalks, respectively. Feeding with S. aculeata hay had no effects on the liveweight of the ewes during the periods before mating and throughout pregnancy, on mating rate, fertility rate, duration of pregnancy, birth weight, or weaning weight of lambs. Furthermore, feeding with sesbania hay had no effect on either the response of ewes to the oestrous synchronisation programme or on the blood serum concentration and pattern of progesterone during the period extending from the commencement of feeding the ewes sesbania hay (2.5 months before mating) until the time of their lambing.

Salty Soil

Salty soil distributed widely and the engineering characteristic was complicated. The mechanical property had the relationship with spatial arrangement of soil grains, mineral component and occurrence condition of diffluent salt. The soil microstructure was an important factor to engineering characteristics. The influence of diffluent salt recrystallization on soil strength was learned according to the microstructure analysis by using environment scanning electron microscope and additional equipment X-ray energy spectrum (EDX). The influence of microstructure variation on salt soil strength was obtained by direct shear test on the salty soil before and after dehydrating. The results showed that diffluent salt recrystallization affected soil internal structure. The salty soil microstructure character was different before and after dehydrating, which changed the soil- mechanical property of salty soil.

This research deals with the study of top soil electrical conductive regions located within Baghdad City. The research included measuring the dissolved soil material extraction Electrical Conductivity (EC) with an aqueous solution for the top (0-30 cm) soil layer of the study area. As the electrical conductivity values increase by increasing the amount of dissolved salts in principle, we can consider that the aim of this research is to predict the amount and distribution of (soil contamination with salts) which is represented by the (Salt Index), this factor calculated for each soil representative sample taken from the region with a depth of (30 cm). Laboratory (EC) test values measured by the use of solutions (EC) digital meter for the extract of the dissolved soils with a distilled de-ionized water using the ratio of (2:1) .The distributed (EC) values for the field representative soil samples used lately to plot a contour equi-electrical conductivity map and EC soil fluctuation profiles, in which reflected the top soil layer salinity distribution according to Tigris river position in the study area , also it reflects the increase and decrease of this layer salinity in a relation to the river position. This study concluded that the highest soil salinity concentrations located at the southern east part of the study area, while the lowest concentrations are located on the intersection areas with Tigris river stream, other areas in which are few kilometers far from the river stream showed moderate salinity concentrations. These results could be helpful for Environmental and agricultural benefits, through identifying the salty soil pollution region and look for ways of treatment.
