BEST PRACTICES TO CONTROL DUST ON FARMLAND
What You Can Do:
In the Field: modify farming practices to minimize dust
Don’t plow if the soil is dry
and there are high
winds.
Whenever you plow, be sure to plant shortly
after.
Do not disk when average wind speeds exceed
15 mph.
Do not till on fallow and bare ground when
average wind speeds exceed 25 mph.
Cover piles of
fertilizer, compost, or soil.
Minimize soil-disturbing field operations such
as plowing, mowing, and tilling.
Modify the timing and type of operations based
on soil and weather conditions.
Use surface coverings like wood chips, mulch,
or plastic sheeting to help stabilize soil.
Use cover crops like grasses and legumes to
help reduce wind erosion.
Use physical barriers such as fences, straw
bales, and large trees to minimize the flow of
dust.
Pay attention to the dust you are causing: use
water or dust suppressants when substantial
dust is blowing offsite.
On Dirt Roads: limit dust generation
Decrease speed and number of trips
when driving on dirt roads.
Drive slower than 15 mph on dirt roads
within ¼ mile of public highways,
schools, or residences.
Plant vegetation near an unpaved road
to serve as a dust barrier.
Apply gravel or dust suppressant to
dirt roads whenever necessary.
Pay Attention to Forecasts!
If high winds are forecast, adjust your
schedule to avoid time outdoors, and
avoid activities that will stir up dust.
Health Effects
Airborne dust particles can be inhaled, and lodge deep in
the lungs. Short term respiratory problems can include
pain, shortness of breath and difficulty breathing.
Long term problems can include decreased lung function,
aggravated asthma, bronchitis and other respiratory
illnesses.
Particle pollution can also impact the heart and
cardiovascular system.
Although particulate matter can cause health problems for
everyone, certain people are especially vulnerable to
adverse health effects. Sensitive populations include
children, seniors, exercising adults, and those who already
have respiratory or heart conditions.
Protect Yourself
During high wind events, levels of particles can be
extremely high for short-term periods. Try to minimize
time outdoors and physical activity.
After a wind event, minimize activities that will stir dust
particles back up into the air.
If you have to be outdoors when particle levels are high,
use respiratory protection.
Note that respirators are not recommended for people
with any kind of breathing problem because they limit
the flow of air. Consult with your doctor before choosing
to use a respirator.
