2009 Nutrient Management
Protocol for Ontario Regulation 267/03 Made under the Nutrient Management
Part 11 - Outdoor Confinement Areas
11.1 Snow That Contains Manure
Part VII of the Regulation allows a person to store or use snow
which has been removed from an outdoor confinement area and that
contains manure subject to certain conditions.
Snow that contains manure, removed from an outdoor confinement
area, is known in the industry as "feedlot snow", "winter
yard scrapings" or "brown sugar". This material is
of extreme bulk relative to nutrient content, and is known to cause
handling and storage difficulties on many operations where outdoor
livestock housing is used.
11.1.2 Parameters for Snow Containing Manure from Permanent Outdoor
For the purposes of Part VII of the Regulation the snow containing
manure is characterized by;
- having originated from a permanent outdoor confinement area;
- the presence of ice or snow crystals;
- the presence of no other foreign materials except livestock
urine, feces, feed or bedding;
- a dry matter content of no greater than 16%; and
- being solid despite its low dry matter content such that this
material cannot be pumped at time of handling or application,
but rather it can be piled or handled as a solid.
The preferred method for determining the nutrient content described
above is through using pooled samples (10 litres each) which are
subjected to analysis in triplicate. Sampling and laboratory methods
for determining dry matter, total nitrogen and total phosphorus
are outlined in the Sampling and Analysis Protocol.
11.1.3 Bedding and Feed in Snow
Snow that contains manure is permitted to contain some bedding
and feed. This is in recognition of the fact that sometimes feed
and bedding will become mixed in with the snow after a storm event
and may be removed when the snow is removed. Not all scrapings from
an outdoor confinement area will be able to meet the parameters
described above. Any winter application of manure that does not
meet the above guidelines must be in compliance with the Regulations
for winter spreading contained in Part VI of the Regulation.
