Avoid spreading when the wind blows toward populated areas or immediately before weekends and holidays, when nearby neighbors are likely to be engaged in outdoor and recreational activities. Spread in the morning when air is warming and rising rather than in the late afternoon. Follow weather reports to advantage. Sunny, low-humidity days reduce odors. Turbulent breezes dissipate and dilute odors.
Rain removes odors from the atmosphere.
Avoid spreading near heavily traveled highways, and keep manure from spilling on public roads. If a spill does occur, clean the road promptly. Minimize agitation and exposure of manure to air during preparation for unloading, hauling, and spreading. Mixing, spraying, and agitating, at any step of the operation, however necessary for proper functioning, releases odors into the air. If possible, incorporate manure during or immediately after land application by injecting it into the soil or plowing or disking the soil.
