Interesting question! This may be useful...

Minerals Required for Turfgrass Growth and Development

Turfgrasses require 16 chemical elements for growth and development. These
elements can be divided into two main groups based on where they are
obtained by turf plants. The first group, carbon (C), hydrogen (H), and
oxygen (O), are obtained from atmospheric carbon dioxide and water and
comprise most of the turfgrass body.
The second group are minerals derived from soil or fertilizer application.
This group can further be divided into three groups based on the quantities
in which they are used by turf plants. The macronutrients, nitrogen (N),
phosphorus (P), and potassium (K) are used in relatively large quantities by
turfgrasses. The secondary nutrients, sulfur (S), calcium (Ca), and
magnesium (Mg), are used in somewhat smaller amounts by turf plants, and
micronutrients, iron (Fe), manganese (Mn), zinc (Zn), copper (Cu),
molybdenum (Mo), boron (B), and chlorine (Cl) are used in the smallest
amounts by the plants.

It would seem that the volumes of CI applied through tap water are so
minimal (depending on location) that by and large, neutralization is not
required.

Just my own conclusion, of course...
