Article 10 - (Agriculture & Markets) SALE AND ANALYSIS OF COMMERCIAL FERTILIZER
146-G - Retail sale.

  146-g.  Retail  sale.  Any retailer who sells or offers for sale to
  consumers specialty fertilizer in which the available  phosphate  (P205)
  content is greater than 0.67 percent, shall:
(a) display such phosphorus-containing specialty fertilizer separately
  from non-phosphorus specialty fertilizer; and
(b)   post  in  the  location  where  phosphorus-containing  specialty
  fertilizer is displayed a clearly visible sign which is at  least  eight
  and one-half inches by eleven inches in size and states that:
"Phosphorus  runoff  poses a threat to water quality. Therefore, under
  New York law, phosphorus-containing fertilizer may only  be  applied  to
  lawn or non-agricultural turf when:
(1)  A  soil  test  indicates that additional phosphorus is needed for
  growth of that lawn or non-agricultural turf; or
(2)  The  fertilizer  is  used   for   newly   established   lawn   or
  non-agricultural turf during the first growing season."
