Salinity assessment of irrigation water and soil for al-seleit agricultural scheme (Sudan)


Gibla Omer Adam, Basma MA Ali, Esraa Omer Adam

This study was conducted to measure the effective parameters that, determine irrigation water quality and agricultural soil characteristics at, Alseleit Agricultural Scheme. Depending on the cultivated crop type, soil and irrigation water samples were collected from ten farms. Minerals content of soil and water samples were measured by (ICP) spectroscopy. Salinity parameters SO4=, Cl-, and NO3- were determined by UV-VIS spectrophotometry. Sodium adsorption ratio was calculated for water and soil samples. Water samples showed minerals content mean as, Ca (43.82ppm), Mg (11.61ppm), Si (21.89ppm), K (3.80 ppm) and Na (0.87ppm). Micro nutrients and toxic minerals showed very low availability. Only one sample showed significantly high Fe (59.2ppm). Soil minerals content means were, Ca (15,999.9ppm), Mg (6,552.8ppm), K (2,183.74ppm), Na (1,781.32ppm), Mn (510.22ppm), Ni (65.51ppm), Ti (4,817.9ppm), Zn (43.24ppm), and significantly high Fe content (mean 29,168.6ppm). The mean values of toxic minerals, Al, Ba, Sr and V, were relatively high in soil samples. Both water and soil samples showed low SO4=, Cl-, and NO3- content. SAR mean value was (16.21meq) for soil and (0.161meq) for irrigation water samples.
