Continue to refer to Manure Spreading Advisory #2 (March 10, 2014) for managing risks with manure spreading: http://www.farmwest.com/node/1342
Producers are responsible for decisions regarding manure spreading. Legislation gives no specific dates for manure spreading but it does not allow for manure to be spread in a manner that causes pollution.
This Update is produced by government, in partnership with industry, to provide guidance to farmers regarding the Agricultural Waste Control Regulation and the ENVIRONMENTAL MANAGEMENT ACT. If a discrepancy arises between this document and the legislation, the legislation takes precedence. Following this advisory does not relieve anyone from their obligations under the LEGISLATION. The Province of British Columbia does not guarantee the accuracy or completeness of the information referenced here from legislation, and in no event is the Province liable or responsible for damages of any kind arising out of its use.

Assumptions about Manure Nutrient Contents
The following nitrogen (N) and phosphorus (P) concentrations were used to estimate the amount of P for every 100 kg total N in 3 manure types: Manure Type Total N (%, as received) Total P (%, as received) N : P ratio Liquid dairy (quite watery) 0.20 0.04 5.0 : 1 Broiler chicken 3.47 1.09 3.2 : 1 Hog (covered pit) 0.63 0.14 4.5 : 1
