Lime is used to adjust the level of acid in the soil. Below is a detailed description of the process and importance of liming.

Soil pH

A fertility program for woody plants begins with obtaining an analysis of soil pH or level of acidity. Soil pH is measured on a scale of 0 to 14. Soils with a pH below 7 are acidic while those above 7 are alkaline. Adjusting pH levels is important not only because specific plants grow best within a certain range of pH, but also soil pH affects the availability of both major and minor nutrient elements. Furthermore, soil pH influences the level of microbial activity in soils. Microbes involved in mineralization of organic matter are most active between a pH of 6 and 7. At extremes in pH, many nutrients occur in forms unavailable for uptake by plant roots. Figure 1 shows the relationship between pH and availability of elements essential to plant growth.

Analysis of soil pH levels should be routinely made prior to any planting in nursery soils or at landscape sites. Typically limestone is required to adjust pH upward while sulfur is used to lower pH. It is best if these materials are incorporated into soils prior to planting, since surface applications are slow to affect pH levels. Most liming and sulfur recommendations are based on the assumption that the material is worked in to depths of 8 inches. Deeper incorporation of either limestone or sulfur will require adjustments in rates to accommodate larger volumes of soil.
