Soil Fertility Index and Soil Evaluation Factors, Are these equations suitable for alkaline soil? Soil Fertility Index (SFI) = pH + organic matter (%, dry soil basis) + available P (mg kg-1 dry soil) + exch K (cmolckg-1) + exch Ca (cmolckg-1) + exch Mg (cmolckg-1)-exch Al (cmolckg-1) Soil Evaluation Factor (SEF) = [Exch K (cmolckg-1) + Exch Ca (cmolckg-1) + Exch Mg (cmolckg-1)-log(1 + exch Al (cmolckg-1)] × organic matter (%, dry soil) + 5
What is the retardation factor of a pulse of dissolved benzene move through organic-rich wetland soil (organic carbon fraction of soil, foc=50%) if the effective porosity is 0.4 and the bulk density of the soil is 1.5 g/cm3.

Determination of Total Chlorine Residual Description of the MethodThe chlorination of a public water supply produces several chlorinecontaining species, the combined concentration of which is called the total chlorine residual. Chlorine is present in a variety of chemical states, including the free residual chlorine, which consists of Cl2, HOCl and OCl–, and the combined chlorine residual, which consists of NH2Cl, NHCl2, and NCl3. The total chlorine residual is determined by using the oxidizing power of chlorine to convert I– to I3-. The amount of I3- formed is then determined by titrating with Na2S2O3 using starch as an indicator. Regardless of its form, the total chlorine residual is reported as if Cl2 is the only source of chlorine, and is reported as mg Cl/L. The description here is based on Method 4500-Cl B as published in Standard Methods for the Examination of Water and Wastewater, 20th Ed., American Public Health Association: Washington, D.

Jansen Gas creates three types of aviation gasoline(avgas), labeled A, B, and C. It does this by blendingfour feedstocks: Alkylate; Catalytic CrackedGasoline; Straight Run Gasoline; and Isopentane.Jansen’s production manager, Dave Wagner, hascompiled the data on feedstocks and gas types inTables 4.6 and 4.7. Table 4.6 lists the availabilitiesand values of the feedstocks, as well as their keychemical properties, Reid vapor pressure, and octanerating.
