An introduction to soil acidity and liming for farmers and gardeners to increase crop income and improve lawn and garden performance. Topics covered include soil pH, soil testing, liming standards and application and incorporation of lime into soil.
Soil samples that determine lime and fertilizer needs of crops routinely come from the top 4 to 8 inches of soil. However, deep soil samples will be needed for the Phosphorus Loss Assessment Tool (PLAT), and this publication describes how to take these 28- to 32-inch deep samples.
