WebThe University of California advises that the accuracy of soil pH readings is plus or minus 0.5 pH units. In other words, your 7.5 soil may be anywhere between 7.0 and 8.0. Understanding Soil pH WebThe pH scale The pH scale is used to rank solutions in terms of acidity or basicity (alkalinity). Since the scale is based on pH values, it is logarithmic, meaning that a change of 1 pH unit corresponds to a ten-fold change in H ^+ + ion concentration.

WebTomato plants like slightly acidic soil, with a pH of 6.0 to 6.5. If your soil is too acidic (low pH) or too alkaline (high pH), nutrients become less available, which slows tomato plant growth. You can use sulfur to acidify soil (lower pH) or lime to “sweeten” soil (raise pH) for tomato plants. Of course, there are other factors that ...
