Updating the database of the Illinois Compiled Statutes (ILCS) is an ongoing process.
Recent laws may not yet be included in the ILCS database, but they are found on this site as Public
soon after they become law. For information concerning the relationship between statutes and Public Acts, refer to the
Because the statute database is maintained primarily for legislative drafting purposes,
statutory changes are sometimes included in the statute database before they take effect.
If the source note at the end of a Section of the statutes includes a Public Act that has
not yet taken effect, the version of the law that is currently in effect may have already
been removed from the database and you should refer to that Public Act to see the changes
made to the current law.
(415 ILCS 65/5a)
Fertilizer; application restrictions.
(a) No applicator for hire shall:
(1) Apply phosphorus-containing fertilizer to a
lawn, except as demonstrated to be necessary by a soil test that establishes that the soil is lacking in phosphorous when compared against the standard established by the University of Illinois. The soil test required under this paragraph (1) shall be conducted no more than 36 months before the intended application of the fertilizer and by a soil testing laboratory that has been identified by the University of Illinois as an acceptable laboratory for soil testing. However, a soil test shall not be required under this paragraph (1) if the fertilizer to be applied is a 0% phosphate fertilizer or the fertilizer is being applied to establish a lawn in the first 2 growing seasons.
(2) Apply fertilizer to an impervious surface,
except where the application is inadvertent and fertilizer is swept or blown back into the target area or returned to either its original or another appropriate container for reuse.
(3) Apply fertilizer using a spray, drop, or rotary
spreader with a deflector within a 3 foot buffer of any water body, except that when this equipment is not used, fertilizer may not be applied within a 15 foot buffer of any water body.
(4) Apply fertilizer at any time when the lawn is
frozen or saturated. For the purposes of this paragraph (4), a lawn is frozen when its root system is frozen (typically 3 or 4 inches down), and a lawn is saturated when it bears ample evidence of being or having been inundated by standing water.
(b) This Section does not apply to the application of fertilizer on property used in the operation of a commercial farm, lands classified as agricultural lands, or golf courses.
(c) This Section does not apply to the application of lawn repair products.
(d) Paragraph (1) of subsection (a) of this Section does not apply to the application of animal or vegetable manure that is ground, pelletized, mechanically dried, packaged, or supplemented with plant nutrients or other substances other than phosphorus.
