Practices that do not involve any physical changes to their existing
operations should be implemented by producers. One such practice
is timing of manure application. More frequent manure application
and therefore less storage time is most desirable from the standpoint
of emissions control. However, to make the best use of manure nutrients,
manure application should coincide with the time when crops are
most in need of manure nutrients. The compromise, then, is to apply
manure in the spring and in the fall, or in both seasons, but plan
the applications for those times when they will be least offensive
to neighbors. Producers should avoid holidays and be aware of wind
conditions, so that neighbors will be in the downwind direction
as little time as possible. Application in early evening, when
air is still, is conducive to greater emissions than at midday
, when air is more turbulent, allowing odor and other gases to
dissipate more readily. Notifying neighbors of manure application
plans is also a very important strategy to be undertaken.
