SOIL AND WASTE pH 1.0 SCOPE AND APPLICATION 1.1 This method is an electrometric procedure for measuring pH in soils and waste samples. Wastes may be solids, sludges, or non-aqueous liquids. If water is present, it must constitute less than 20% of the total volume of the sample. 2.0 SUMMARY OF METHOD

The accurate and reliable measurement of soil pH is critical for understanding soil health and nutrient availability, and this SOP provides a standardized procedure for pH measurement to ensure consistency and accuracy in results.
Generally, a soil pH between 6.0-7.5 is acceptable for most plants, as most nutrients are available in this pH range (FAO 2021). Soil pH may be measured electrometrically with a pH meter. Water is the usual suspension medium for the soil sample, but 1 M (mol.L-1) KCl or 0.01 M CaCl 2 are also used, particularly to minimise the effect of --
The soil pH is measured by suspending soil in a reagent water (1:1 mass ratio of soil to water) for a designated amount of time and then measuring the pH of the aqueous solution after is has been separated from the soil.
Lab 9 - Soil pH and Soil Testing Objectives: • To measure soil pH and observe conditions which change pH • To distinguish between active acidity (soil solution pH) and exchangeable acidity • To understand the function of CO2 in determining pH • To understand liming reactions and the calculation of lime requirements
Soil pH and Electrical Conductivity (EC) • Soil pH is a measure of ionized H (H+) in the soil solution. All chemical and biological reactions in soil are influenced by soil pH. Soil salinity affects crop growth and soil structure, and is estimated from measurement of soil electrical conductivity. The electrical conductance is expressed as mS/cm.

Aug 2, 2017 · soil pH is important and outlines the impact of soil type and texture on pH. It describes how and when to test soils for pH, how to calculate the amount of lime or other neutralising materials required, which liming product(s) to use and how and when to apply them. Soil pH is a measure of the relative acidity or alkalinity of a soil.
