Abstract. Assessing the effectiveness of management strategies to reduce agricultural nutrient efflux is hampered by the lack of affordable, continuous monitoring systems. Generalized water quality monitoring is possible using electrical conductivity. However environmental conditions can influence the ionic ratios, resulting in misinterpretations of established electrical conductivity and ionic composition relationships. Here we characterize specific electrical conductivity (k25) of agricultural drainage waters to define these environmental conditions and dissolved constituents that contribute to k25. A field investigation revealed that the magnitude of measured k25 varied from 370 to 760 µS cm-1. Statistical analysis indicated that variability in k25 was not correlated with drainage water pH, temperature, nor flow rate. While k25 was not significantly different among drainage waters from growing and post-growing season, significant results were observed for different cropping systems. Soybean plots in rotation with corn had significantly lower conductivities than those of corn plots in rotation with soybeans, continuous corn plots, and prairie plots. In addition to evaluating k25 variability, regression analysis was used to estimate the concentration of major ions in solution from measured k25. Regression results indicated that HCO3-, Ca2+, NO3-, Mg2+, Cl-, Na2+, SO42- were the major drainage constituents contributing to the bulk electrical conductivity. Calculated ionic molal conductivities of these analytes suggests that HCO3-, Ca2+, NO3-, and Mg2+ account for approximately 97% of the bulk electrical conductivity.

This study evaluated the suitability of an adsorption technique in drainage water treatment for irrigation purposes. The water samples for this study were sourced from different spots of Al-MASAB AL A’AM river. Three different locations (Latifia, Yusufiyah, and Swerah area) were considered in this study. Several studies have reported the use of activated carbon and ion exchangers for water treatment. In this work, a cheap alternative bio-filtration media (activated carbon derived from Apricot stones (ASAC)) was used. Several parameters are required in this technique for various estimations; such parameters include the chemical and physical properties of the water samples (like the pH, ionic concentration, electrical conductivity (EC), and total dissolved solids (TDS). The Freundlich equations was also applied to study the chemical adsorption process using ASAC. Also calculated were the adsorption constant (k) and the number of adsorbents (n). From the results of this study, the applied process was suitable for the removal of Ca+2, Mg+2 and CO3-2 ions from the sampled water.
