Understanding a Soil Test

Soil pH is a measurement of the concentration of hydrogen ions. The level of concentration determines whether the soil is acidic or alkaline. Acid soils require limestone to raise the pH whereas alkaline soils may need acid applications (elemental sulfur) to reduce soil pH. Most soils have a pH range from 4.0 to 8.5, with slightly acidic conditions being most productive. However, different grass species vary in their ability to tolerate pH conditions…  View entire article
