In VRT spreading, should we put TITAN XC on both the phosphate and potash products?

If we put TITAN XC on only one fertilizer product, which should we put it on?

TITAN XC is designed to be applied with all dry fertilizer applications to increase the efficiency of the products being applied. However, if only one must be chosen, we would typically suggest that TITAN XC be used on the largest application of fertilizer to provide the most fertilizer efficiency.
