WebSoil pH should be measuredinthefibrous rootzone(ie.0-20cmdepth) aswell the deeper root zone (>20cm depth). Make sure the soil samples are taken inside the irrigation wetting pattern. Analysis of some mid row samples can also provide a good indication of the effect of vineyard management practices on soil pH. Method 1) Take three surface soil ...

WebA logarithmic scale is used to measure a soil's pH. pH= 1/log (H+) That is, a change of one unit in the pH scale represents a 10-fold change in acidity or alkalinity A soil with a pH of 5.0 is 10 times more acidic than a soil with a pH of 6.0 and 100 times more acidic than a soil with a pH of 7.0.
