Salt index is a reliable, relative measurement used to determine the salt strength of differing fertilizer materials. It allows one to differentiate the potential impact of fertilizer materials placed near a germinating seed. Watch Nutrien Director of Agronomy Dr. Robert Mullen discuss how salt index is determined analytically, how it is calculated for different fertilizer materials, and how agronomists can use that information when making starter fertilizer decisions.
