Advisories

  • Manure Spreading Advisory #4 for 2018: South Coast Region

    In general, manure application on any crops is not advised until further notice. See below for advice on avoiding overflowing manure pits.

    • 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.
    • Please read the entire advisory for details and important information to assist producers with decision-making about manure application.

    The Manure Spreading Advisory Committee (consisting of industry and government representatives) is advising against manure applications due to lower air temperatures, the increased potential of significant rain events, and lack of vegetative cover and/or reduced nutrient uptake of cover crops. The committee will monitor weather and soil conditions and will issue further advisories as conditions change.

    Principal environmental risks associated with manure application:

    • surface runoff of manure nutrients and pathogens to water courses
    • short-circuit flow of manure nutrients and pathogens to water courses though drain tiles
    • soil compaction from operating heavy equipment on fields that are very wet

    This advisory 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.

    Additional Information

    Manure Storage

    • Winter manure applications are not recommended. It is essential to have enough manure storage to include the average expected precipitation plus account for unforeseen circumstances such as excessive precipitation.
    • Develop a contingency plan to outline an effective response in case of an emergency. The plan should include identification of abandoned pits and other storage facilities, contact information for vacuum trucks or commercial operators, and easy access to the provincial spill reporting hotline: 1-800-663-3456.

    Harvested Annual Crops (including corn and vegetables)

    • Manure applications are not recommended.

    Berry crops

    • Manure applications are not recommended.

    Perennial Grassland

    • Winter manure applications are not recommended. All measures must be taken to address the chance of overflowing manure storage (see Manure Storage above). If manure storage is not adequate and overflowing might occur please contact one of the BC Ministry of Agriculture staff on the first page.

  • 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.

     

    Figure 1. Cumulative rainfall in October recorded in 2016 and 2017 at the Abbotsford airport.

     

    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.

  • Manure Spreading Advisory #3 for 2018: South Coast Region

    Date: September 1, 2018
    • Perennial grasses continue to benefit from fall manure applications when applied to meet crop nutrient needs.
    • Manure applications for cover crops and newly seeded grasses should be based on a soil test and only applied if the cover crop will become well established to uptake nutrients prior to the end of the growing season. Manure applications on harvested or fallow fields are not recommended.
    • 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.
    • Consider wind speed and direction when applying manure and how it can have a negative impact on your neighbors. The wind can also increase ammonia loss and soil loss through erosion.
    • Reminder that field stored solid agricultural wastes (except vegetation waste) must be covered by October 1.

    Please read the entire advisory for details and important information regarding manure applications.

    Additional Information

    Manure Storage

    • Winter manure applications are not recommended. It is prudent to have enough manure storage to include the average expected precipitation plus account for unforeseen circumstances such as excessive precipitation.
    • Plan manure applications to empty storage facilities before the rainy season. Manure applications in the fall are recommended only for forage grasses.
    • Develop a contingency plan to outline an effective response in case of an emergency. The plan could include identification of nearby abandoned pits, contact information for vacuum trucks, and easy access to the provincial spill reporting hotline.

    Harvested Annual Crops (including corn and vegetables)

    • Manure applications are not acceptable on harvested fields.

    Cover Crops

    • Manure applications should only be considered if a fall soil test shows the need for nutrients and a winter cover crop has been or will be established before the end of the growing season.
    • As the days get shorter and colder, cover crops are less able to take up nutrients. Also, as fall rains arrive, the risk of nutrient runoff and leaching increases.
    • Residual nutrients from the summer crop may be present in the soil and in sufficient quantity to support the winter cover crop.

    Perennial Grassland

    • 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.
    • Application rates should meet crop nutrient requirements.
    • Appropriate buffer widths should be maintained to minimize runoff risks. 

    Berry Crops

    • Fall manure applications for berry crops is not necessary or recommended. 
    • If manure is used on fields that are being renovated for new plantings, a cover crop should also be planted. The cover crop should be planted in a timely manner such that it becomes well established prior to the end of the growing season. Consider the recommendations made for raspberries in the Berry Production Guide, http://productionguide.agrifoodbc.ca/guides/14

  • July UPDATE to Manure Spreading Advisory #2 of 2018: South Coast Region

    Date: July 2, 2018

    Refer to Manure Spreading Advisory #2 of 2018 (April 23, 2018) for the current Advisory.  The following Update does not change the Advisory.   

    Considerations for spreading manure during warm weather:

    When spreading manure during the summer, it is important to consider the impact of high temperatures on nitrogen (N) loss from manure.  Volatilization of ammonia during and shortly after application is greatly increased when temperatures are high.  Several other factors including manure composition, time to incorporation, wind, soil pH and moisture, and application method will impact ammonia loss as well.  

    Losing ammonia from manure is a direct loss of its fertilizer value and should be considered when planning application timing and calculating manure’s contribution to crop N requirements.

    Spreading manure when temperatures are above 25°C can result in a loss of 50% of the ammonia N within three hours of application.

    To avoid losing the readily available ammonium N from manure

    • Apply during the cooler times of day and when wind speeds are low
    • Use spreading equipment which results in less ‘air time’, such as a drop hose or injection system

    Farmwest.com provides an Ammonia Loss From Manure calculator which can help predict the potential N loss during manure application.
