Web16 aug. 2011 · Soil pH is the most routinely measured soil property for assessing plant nutrient availability. Nevertheless, there are various techniques for soil pH measurement, which vary with regard to the solution used and the soil-to-solution ratio. Soil pH is commonly measured in water or 0.01 m CaC1 2. Web20 sep. 2024 · We prepared three different soils for plant growth at the optimal pH values selected after the preliminary germination tests on agar: pH5 (acid), pH6 (sub-acid), and pH7 (neutral). To obtain the selected pH values from the natural soil, a liming method was used according to literature ( Brown et al., 2008; Thompson et al., 2016 ).
