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.
