I think it will be education and enforcement at the retail levels.

Scotts Starter for 5000 square feet is 15lbs.
So roughly administering 3lbs per 1000 square feet.

It has an advertised N-P-K of 24-25-4.
So roughly 24% Nitrogen, 25% Phosphorus, 4% Potassium, and 47% inert filler.

3lbs would contain .75 lbs of Phosphorus, if my math is correct.

That would violate the .5 lbs annually allowed by the new law.

Other than new lawn, repair, or one tested and found to be deficient in phosphorus is to use Starter; and the remainder is supposed to be no phosphate.

We also have application restrictions based on conditions.

Not sure how much tighter they could go.
