Ammonia reduction measures for storage of
slurry and urine
slurry and urine
•slurry
and urine pits must be covered with a stable
surface crust layer
or other covering that effectively reduces
ammonia emissions
•filling must take place
beneath the covering.
Since 1995, this affects
farms with > 10 animal units in three counties in southern Sweden, and since
1997 in the rest of Götaland and on the plains of Svealand.
Slurry pits can either be
covered with a natural crust, straw, peat, plastic, leca
pebbles, a roof or other covering materials that effectively
reduce ammonia emissions. Filling beneath the covering is to prevent the slurry or
urine from breaking the cover or ending up on top of the cover.
