Livestock Waste Management Practices And Legilation Outside Br

23
The Netherlands' livestock waste management regulations are the most detailed
and perhaps the most dynamic. Phosphorus is largely the basis on which the
use of livestock manure is regulated. The basis for using phosphorus rather
than nitrogen as the indicator is associated with experience in the Netherlands
which suggests that once the immobilization capacity of a soil profile is
saturated, the leaching of phosphorus through the profile can be most
significant. Where nutrient loading is the water quality concern, phosphorus
may be the limiting nutrient. For this reason, it is suggested that surface water
may be 10 to 15 times as sensitive to phosphorus loading as it would be to an
equivalent nitrogen loading. Key regulations include:
. national standards for quantity of manure, timing and method of
application
. detailed commodity specific manure storage regulations
. manure storage permits required
. restrictions on emissions of ammonia
. efficient transport and transfer of surplus manure
. indirectly enforce N, P, and NH standards (reviewed every 2 - 5 years)

. slurry application by land injection methods
. restrict farm practices in designated water protection zones
. prohibition of expansion and starting new livestock enterprises
. detailed winter spreading, snow and frozen soils specifications
. manure must be incorporated within 24 hours
. limitations of chemical fertilizer use
. obligated to keep farm records of slurry and manure production
