Why Soil pH Measurement is Important
Garden soils are often described as acidic (sour) or alkaline (sweet). Unfortunately, the meanings of these terms and their relationship to plant growth are not clearly understood by some gardeners. The relative acidity or alkalinity of soil is indicated by its pH. The pH scale runs from 0 to 14. Any pH reading below 7 is acidic and any pH above 7 is alkaline. A pH of 7 indicates a neutral soil. The pH is important because it influences the availability of essential nutrients. Most horticultural crops will grow satisfactorily in soils having a pH between 6 (slightly acid) and 7.5 (slightly alkaline). Since most garden soils in Iowa are in this range, most gardeners experience few problems with soil pH.

There are a few plants that require a soil pH of 4.5 to 5.5. These "acid-loving" plants include azaleas, rhododendrons, and blueberries. The soil pH for these plants can be lowered by incorporating elemental sulfur (S) into the soil. Since the soil acidifying response to elemental sulfur is slow, it should be applied and incorporated a year before planting. Working Canadian sphagnum peat into the soil is another method to lower pH.

For most plants, however, a soil pH below 6.0 is undesirable. Strongly acid soils need to be limed to raise the pH to near neutral
levels. Liming materials include ground limestone which is mainly calcium carbonate (CaCO3) and dolomitic limestone which contains
CaCO3 and some magnesium carbonate (MgCO3). Since most Iowa soils do not need to be limed, apply liming materials only when
recommended by a soil test.
