OCTOBER Update to Manure Spreading Advisory #3 of 2018: South Coast Region

Date: October 1, 2018

Refer to Manure Spreading Advisory #3 of 2018 (September 1, 2018) for the current Advisory.  The following Update does not change the Advisory.

For the past two years, significant rainfall started by mid-October in the Fraser Valley, above the long term average (see Figure 1 below).  Forecasts may provide some indication as to what can be expected this year, better to plan and be prepared in advance of the rainy season when manure applications are not recommended.

Until the final Spreading Advisory is issued, refer to the current one, and note that:

  • Manure should not be applied within 8 meters of ditches or watercourses. Buffer width should be increased for slopes greater than 5% and/or if the potential for runoff exists.  Always check the precipitation forecast prior to spreading.
  • Manure application on perennial grasses is usually appropriate as long as crop growth and warmer weather patterns (greater than 5oC) continue; fields are trafficable; and precipitation does not create runoff. 
  • Reminder that field stored solid agricultural wastes (except vegetation waste) must be covered after October 1.


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 Regulationand 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.
