New York Agriculture & Markets Law
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:
display such phosphorus-containing specialty fertilizer separately from non-phosphorus specialty fertilizer; and
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:
A soil test indicates that additional phosphorus is needed for growth of that lawn or non-agricultural turf; or
The fertilizer is used for newly established lawn or non-agricultural turf during the first growing season."
