Soil and Agriculture After the Aswan High Dam

“…Therefore, a certain strategy should be adapted for each kind of stresses soils. The common problem concerning the Egyptian soil fertility represents in decline the soil fertility after building the High Dam and decrease of potassium content in the Egyptian soils (Khalifa and Moussa 2017).…”

“…In Egypt's Nile Delta, the water table has been rising much closer to the surface in many places in particular near to the Mediterranean coastal lands after building High Dam. Inefficient and/ or absence drainage systems has been contributed to the development of salinity and waterlogged soils, which reduced land productivity by 15-30% (Khalifa and Moussa 2017).…”

S TRESSED environments have long been a question of great interest in a wide range of fields. So, many considerable literatures have grown up around this theme. In Egypt, there are several common problems related to the stressed environments. These stresses include decline of soil fertility, soil salinity and alkalinity, soil water logging, salt-affected soils, soil pollution, climate change, overpopulation growth, urban sprawl, land degradation, deterioration of natural resources, etc. More generally, national income will decline and will in turn result in the spread of social and political problems. Kafr El-Sheikh governorate can be considered one of the most important areas in Egypt, which calls "the governorate of the hope and the future" due to its location and wealths. Whereas, this governorate suffers from the most common stresses in Egypt including pollution, salinity, alkalinity and waterlogging. Great problems have been recorded in Kafr El-Sheikh related to stressed environments and suggested solutions also have been addressed. Therefore, a sustainable management should be adapted for overcoming these stressed environments in Kafr El-Sheikh.

“…The issues of soil degradation and loss of soil fertility arose when the Aswan high dam was constructed. The water table has been rising substantially closer to the surface in various parts of Egypt's Nile valley, causing soil salinity (Khalifa and Moussa, 2017).…”

Soil properties including soil salinity is of importance for determining crop production. Therefore, the objective of this study was to assess the influence of soil properties (pH, EC, soluble cations and anions, SAR, CaCO3 and OM) on the production of wheat and sugarcane grown at Upper Egypt, Aswan, Egypt. An agronomic classification proposed by Smith and Doran (1996) was used for soil salinity. Forty-eight and twenty-two surface soil samples were collected at depth 0-30 cm for soils cultivated with wheat and sugarcane, respectively. Regarding the area cultivated with wheat plants the soil salinity, according to the measured EC1:1 values can be classified to 29.16% of the collected soil samples were none-saline (less than 1.25 dSm -1 ), and 47.9 % were slightly saline (less than 2.53 dSm -1 ) with a total of 77.12%. Meanwhile, 10.4%, 2.08% and 10.4 % of the soil samples were saline, strong saline and extremely saline, respectively with a total of 22.88 %. Moreover, the samples collected from sugarcane cultivated soils, showed 19.04% as non-saline, and 38.08% as slightly saline, 38.08% as saline, and 4.76% as highly saline. This indicates that 77.06% of the samples of wheat soil and 57.12% of the samples of sugarcane soil have a safe salinity level but 22.88% of wheat soil samples and 42.84% of the sugarcane soil samples show a hazardous salinity level. Based on the correlation study and multivariate statistical analysis, the wheat grain yield was affected negatively by the soil bulk density, EC, soluble cations of Ca, Mg, Na and K, and anions of Cl and SO 4, SAR, and CaCO3 content. However, the sugarcane yield is negatively correlated with the soil bulk density and positively correlated to the porosity. Finally, it could be concluded that regarding the soil management for the growing wheat and sugarcane at Aswan, Egypt, should consider the soil physical characteristic including bulk density and poro sity and chemical characteristics including salinity levels, soil solution composition and CaCO3 content should be taken to consideration.
