Abstract

Site-specific management of soil pH is a precision agriculture practice that can provide positive economic and environmental impacts on modern crop production. This publication addresses several frequently asked questions related to the meaning of soil pH, lime requirement, and quality of data used to prescribe site-specific management of soil pH. What is soil pH? The term “pH” is defined as the negative logarithm of the hydrogen ion activity, and values range from 1 (very acidic) to 14 (very basic).
