PB1096 Liming Acid Soils in Tennessee

Soil test results indicate that approximately 50 percent of the cropland in Tennessee is too acid for optimum crop production. Because of this, determining the need for lime should be the first step in developing a sound crop fertilization program. Lime neutralizes excess soil acids and increases pH. If not limed as needed, soils continue to become more acid, reducing the soil’s potential to produce healthy plants and profitable yields.
