If you apply nutrients to crop fields, you are required to
adhere to the setback distance as determined by the
method of application. If nutrients are custom-applied, it
is your responsibility to inform the applicator of the set-
back requirements. The setback indicator chart shown
below may be used to satisfy the Nutrient Management
Program’s reporting requirements. A map is recom-
mended, but not required.
A nutrient application setback is a vegetated area rang-
ing from 10 to 35 feet from an eligible waterway where
nutrients may not be applied in order to protect water
quality. Maryland’s nutrient management regulations
require setback information identifying these areas to be
included on farm nutrient management plans.
Setbacks for Nutrient Application
PAGE 6
• A minimum 10-foot setback is required for all nutrient
applications adjacent to surface waters and streams.
• A 35-foot setback is required when using broadcast
fertilizer application methods. No crops may be grown
on the 10-foot setback except pasture and hay. The
remaining 25-foot setback may have crops, but may
not be fertilized unless a direct application method is
used.
• Pastures and hayfields are subject to a 10-foot
setback.
• Nutrients may not be applied mechanically within the
10-foot setback area.
• Livestock are not allowed in the setback; however,
flash grazing is allowed.
• Fencing to control livestock may not be required in all
cases. If you do not have stream protection measures
in place, contact your soil conservation district to
schedule a farm visit. District staff can evaluate the
site to determine whether fencing is needed or alter-
native practices such as watering facilities, livestock
crossings, or vegetative exclusion will help protect
water quality. The district will provide you with the
necessary documentation to meet this requirement. If
alternative practices do not inhibit access, the depart-
ment may require fencing.
• Livestock sacrifice lots require a 35-foot setback from
sur face water.

**Directed application is a directed spray application (vertical fan or drop nozzle), air flow application, knifed/injected application of nutrients, and planter applied nutrients.
***Broadcast application or sacrifice lots: spinner spreaders (manure or fertilizer), high volume horizontal nozzles, and manure spreaders (box type with beaters, splasher plates for
liquid, side discharge V-type).
