چکیده
Soil salinity/sodicity is becoming a challenge for crop production in Ethiopia’s semi-arid and arid regions. However, more information on soil needs to be available around Abaya Chamo Lakes, South Ethiopia Rift Valley. This study aimed assess characterize determine salt-affected soils’ morphological, physical, chemical properties. The representative pits that were 60 ∗ id="M2"> cm size examined, samples taken from 0–20, 20–40, 40–60 depths based the criteria set agricultural studies. properties determined include color, structure, consistency, bulk density, particle porosity, texture, pH, EC, SAR, ESP, CEC, BS, OC, TN, P, CaCO3−, exchangeable bases, soluble ions (Na+, Ca2+, Mg2+, K+, Cl−, SO4−2, NO3−, CO3−2, HCO3−. soil-analyzed results rated interpreted following guide standardized analysis methods data. of this reveal soils had considerable heterogeneity site highly alkaline very high sodium content, CEC value, low levels organic carbon calcium. dominant cation was sodium, followed by magnesium, calcium, potassium all pits. Similarly, Cl− among anions throughout depth, HCO3−, SO42−, NO3−. findings imply removing salts depth may improve productivity area. Application amendments, including manures residues, also beneficial increasing fertility matter content.

Evaporation Estimation of Rift Valley Lakes: Comparison of Models
Evapotranspiration (ET) accounts for a substantial amount of the water flux in the arid and semi-arid regions of the World. Accurate estimation of ET has been a challenge for hydrologists, mainly because of the spatiotemporal variability of the environmental and physical parameters governing the latent heat flux. In addition, most available ET models depend on intensive meteorological informati...

ماکروسیکلهای شیف باز از اهمیت زیادی در شیمی آلی و دارویی برخوردار می باشند. این ماکروسیکلها با دارابودن گروه های مناسب در مکانهای مناسب می توانند فلزاتی مثل مس، نیکل و ... را در حفره های خود به دام انداخته، کمپلکسهای پایدار تولید نمایند. در این پایان نامه ابتدا یک دی آلدئید آروماتیک از گلیسیرین تهیه می شود و در مرحله بعدی واکنش با دی آمینهای آروماتیک و یا آلیفاتیک در رقتهای بسیار زیاد منجر به ت...
15 صفحه اولCharacterization of Water Level Variability of the Main Ethiopian Rift Valley Lakes
In this paper, the water level fluctuations of eight Ethiopian Rift Valley lakes were analyzed for their hydrological stability in terms of water level dynamics and their controlling factors. Long-term water balances and morphological nature of the lakes were used as bases for the analyses. Pettit’s homogeneity test and Mann–Kendall trend analysis were applied to test temporal variations of the...
متن کاملThe composition of fish communities of nine Ethiopian lakes along a north-south gradient: threats and possible solutions
Fish populations of nine Ethiopian freshwater lakes were quantitatively sampled with a standardized protocol, using multi-mesh gill nets. In total, 27 species were identified, but only 14 species were common. Based on the common species, the fish communities showed large differences in their species composition, except for Lake Abaya and Lake Chamo which were similar. Most fish species were obs...
