PIERRE, S.D. (AP) — South Dakota Gov. Dennis Daugaard has vetoed a measure that would increase a state fee imposed for inspecting commercial fertilizer.

The measure would increase the inspection fee on most fertilizer from 15 cents a ton to 30 cents a ton, with the extra money going to South Dakota State University for research into fertilizer and soil nutrients.

But Daugaard says the measure amounts to a tax increase that helps a state agency that is already getting a substantial budget increase.

The measure’s main sponsor, Sen. Shantel Krebs of Renner, says she believes supporters can get the required two-thirds majorities in both the House and Senate to pass the bill over the governor’s objections. She says the fertilizer industry supports the fee as a way to avoid federal regulations.
