For wind erosion control on more level ground, the strips can be oriented according to the prevailing winds. The areas between the strips can be used for row crop or forage production. The trees can be managed as an alternative enterprise to provide additional farm income. Control strategies for unpaved roads Several products are available for controlling dust from unpaved roads. These products work by attracting moisture, binding dust particles together, sealing the surface, or some combination of these effects.
Chloride salts are the first category of dust suppressant.
These chemicals are moisture attractants, which work by drawing moisture out of the air during periods of high humidity, particularly at night. They also reduce the evaporation rate of water during hot dry periods. This tends to hold the dust on the road surface, although there is no physical bonding. Calcium chloride or magnesium chloride are the most effective moisture attractants. Sodium chloride, or common salt, is cheaper but not very effective alone.
