Ph of sediment
WebbpH was determined with a combined electrode. pH of sediment was measured directly in wet sediment after sectioning of the sediment core. Comparing pH meas urements in wet sediment with pH of supernatant water after shaking wet sediment with distilled water (1:1 on a volume basis) consistently gave pH values 0.2-0.3 units higher in supernatant ... Webb8 nov. 2016 · Measuring soil pH by glass electrode is however purpose oriented. For routine it is 1: 2.5, soil: water ratio. If it is for salt-affected soils (saline, saline-alkali and alkali soils) it needs...
