According to the Van Genuchten model fitting results, the soil residual water content (θr) increased with the soil ion content, which represented a capacity decrease of the soil water supply. At the end of the EK-Bio experiment, the θr values in the soil near (site A) and far from (site B) the electrodes were 19.1 % and 12.1 %, where the soil ion content was 7.92 g/kg and 0.55 g/kg, respectively.

9.2 Measuring Sulfate Content: 9.2.1 Weigh 20 g to the nearest 0.1 g of oven-dried soil and place the soil in a 16 oz. (500 mL) HDPE bottle. 9.2.2 Add 400 mL of distilled or deionized water. This provides an initial dilution ratio of 1:20. 9.2.3 Vigorously shake the bottle of soil/water solution by hand for 1 …

Sep 25, 2018 · For each soil analysis, two grams of air-dried soil was placed in a 50 mL vial and extracted with 20 mL of either 0.02 M strontium chloride, Kelowna extract (0.25 M CH 3 COOH + 0.015 M NH 4 F), Morgan extract (1.4 M NH 4 OAC+1 M HCl + 0.025 M EDTA), or modified Morgan extract (0.62 M NH 4 OH + 1.25 M CH3COOH) (1:10 soil-weight: solution-volume). Vials were placed on a rotary mixer for 15 …

How can I determine the sulphide contents in the soils?

Cs = concentration of the ion in the certified reference solution, ppm DF = dilution factor used. 8.2.1 Example—If the reference solution contains 100 ppm Cl and a technician dilutes 10 mL of the solution to 500 mL, the resulting concentration is: 100 c 500 10 S = 8.3 Calculate concentration of chloride ions in the original soil sample: R DF Fl Cl W ××
