Advisories

  • Manure Spreading Advisory #2 for 2016: South Coast Region

    Date: April 1, 2016

    • Well-planned manure applications are acceptable on most fields that are seeded, will be seeded within two weeks, or have well-established grasses.
    • Do not apply manure prior to significant rain events to avoid nutrient runoff and leaching. Please check your local weather forecast and see the next page for more information.
    • Avoid manure applications on wet areas or saturated soils. Some fields will dry more quickly than others.
    • Please continue to check you have enough manure storage to hold the average expected precipitation plus any excessive precipitation.

     Please read the entire advisory for details and important information to assist in the decision-making process for manure application(s) and storage.

    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 advisory 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.

    Additional Information

    Manure Storage

    • 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.
    • A review of beneficial management practices (such as those found in the Environmental Farm Plan Reference Guide) may help identify improved management practices to alleviate storage issues.

    Established Grasses

    • Manure may be applied throughout the growing season to meet crop nutrient uptake.
    • Avoid spreading on wet fields and saturated soils.
    • Plan manure applications to ensure that storage facilities will be as close to empty as possible by next October.
    • Do not apply manure within 5 meters or more of wet ditches or watercourses. Increase buffer width to avoid any contaminated runoff based on soil, soil cover conditions, slopes greater than 5%, and sensitivity of the area being protected.

    Berry and Vegetable Crops

    • Do not spread manure on berry fields between flowering and harvest or on vegetable fields after planting.
    • The use of properly composted manure should be considered if food safety issues related to manure applications are a concern and/or if nutrient leaching is a concern in sensitive areas such as unconfined aquifers.
    • Verify your food safety plan or program requirements prior to manure and/or compost applications.

    Bare Fields and Fields Prior to Planting

    • Manure applications are not recommended unless the field will be seeded within two weeks of manure application.

  • Manure Spreading Advisory #1 for 2016: South Coast Region

    Date: February 22, 2016

    • It is acceptable to apply manure on some fields but not others.
    • It is acceptable to apply manure on established grasses, fields being seeded within two weeks of application, and berry fields if:
      • Expected precipitation and manure applications will NOT create nutrient or pathogen runoff to surface water (by overland flow or through tile drains)*
      • T-Sum value in your area is greater than 200,
      • Soil temperature is greater than 5oC, and
      • Crop is actively growing (for established crops only)

    *In general, runoff risks are greatest on areas with finer-textured or muck/peat soils, ponded or wet soils that would be compacted by traffic, high water tables (2 feet or less below the surface), or depressions or swales that drain to water courses.

    • Please continue to check you have enough manure storage to hold the average expected precipitation plus any excessive precipitation.
    • Field-stored solid agricultural wastes (except agricultural vegetation waste) MUST be COVERED from October 1 to April 1, inclusive.
    • Please read the entire advisory for details and important information.

    • A review of beneficial management practices (such as those found in the Environmental Farm Plan Reference Guide) may help identify improved management practices to alleviate storage issues.


    Established Grasses and Fields Prior to Planting

    • Manure may be applied to a field of established grasses if all of the following apply:
    1. Less than 5 mm of cumulative rain is expected for the 48 hours following application*
    2. Less than 10 mm of cumulative rain is expected for the 72 hours following application*
    3. The field is not frozen or saturated, subject to flooding or runoff, and it is not tile-drained with the potential for manure to leave the farm
    4. A minimum buffer width of 8 meters (26 feet) is maintained between the application area and sensitive areas and watercourses including ditches
    5. T-Sum value in your area is greater than 200 (see http://www.farmwest.com/climate/tsum)
    6. Soil temperature is greater than 5oC measured at a soil depth of 10 cm
    7. Grass is actively growing


    A couple options to find forecasted rain amounts:


    Berry crops

    • Manure may be applied in late February but it is recommended you confirm from your food safety plan or program to determine the time requirement between manure application and crop harvest.
    • The use of properly composted manure should be considered if food safety issues related to manure applications are a concern or if nutrient leaching is a concern in sensitive areas such as over unconfined aquifers.

  • December UPDATE to Manure Spreading Advisory #4

     Refer to Manure Spreading Advisory #4 of 2015 (November 2, 2015) for the current Advisory: “in general, manure application on any crops is not advised.”

    The following information could be considered for spring manure applications in 2016. If solid broiler manure or litter cannot be injected or incorporated into a perennial grass sward, the next best strategy to reduce nitrogen losses is applying when the grass is taller (Table 1). Co-benefits include odour reduction, reducing risk of runoff and increasing nutrient uptake.

    Table 1. Losses of nitrogen (N) from surface-applied broiler litter decrease with grass height. The N is lost to the air (volatilized) from the ammonium (NH4) fraction of the broiler litter.

The bulk application rate was not specified but is likely close to 6 to 8 tons/ac of broiler litter.

    b. The dollar value was estimated based on the data from Bittman et al. (2013), assuming a cost of $0.75/lb of N in fertilizer (i.e. about $750 per tonne of 46-0-0).

  • Manure Spreading Advisory #4 2015: South Coast Region

    Date: November 2, 2015

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

    What is the concern with spreading manure now? Although a manure application now, under the most favourable conditions, may lead to a growth spurt of grass (Fig. 1), most of the nitrogen in manure that would be spread now will be leached and lost from the soil during the cold, rainy season, before the grass can use it (Fig. 2). Advice: don’t just feed the microbes, feed the crop by waiting to apply manure.

    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


    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 until further notice.


    Berry crops

    • Manure applications are not recommended until further notice.


    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 following staff for additional manure management advice:

  • October UPDATE to Manure Spreading Advisory #3 2015: South Coast Region

    Refer to Manure Spreading Advisory #3 of 2015 (September 1, 2015) for the current Advisory.  The following Update does not change the Advisory.

    “Manure application on perennial grasses is usually appropriate as long as crop growth and warmer weather patterns (greater than 5°C) continue; fields are trafficable; and precipitation does not create runoff” (Manure Spreading Advisory #3 of 2015).

    In 2014 and 2012, significant rainfall started by mid-October in the Fraser Valley. Monthly rainfall was above the long-term average in those years (Fig. 1). What’s in store for October this year? Only time will tell, but weather forecasts are a good tool. As usual, soil moisture conditions, crop cover, and weather forecasts will factor into deciding when the final Manure Spreading Advisory of 2015 will be released.

  • Manure Spreading Advisory #3 for 2015: South Coast Region

    Date: September 1, 2015

    • 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.

    The Manure Spreading Advisory Committee (consisting of industry and government representatives) is advising careful manure application for select fields. The committee will monitor weather and soil conditions and will issue further advisories as conditions change.

    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 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. P

    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 are 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

  • August UPDATE to Manure Spreading Advisory #2

    Refer to Manure Spreading Advisory #2 of 2015 for the current Advisory.  The following Update does not change the Advisory.

    When balancing the goal of maximizing corn yields with the goal of establishing cover crops, consider the effect of cover crop planting date (Table 1).

    Table 1.  Nitrogen uptake by cover crops decreases with later planting dates.  Values are for B.C. South Coast.  Actual uptake depends on crop variety and other factors.

    Approximate Planting DateNitrogen Uptake
    Before August 15Up to 140 kg N/ha
    August 2260 to 95 kg N/ha
    September 530 to 50 kg N/ha (legumes);
    60 to 95 kg N/ha (non-legumes)
    September 15Less than 45 kg N/ha

    Does nitrogen need to be applied in the fall to establish the cover crop?  In many cases, the anser is 'no' or 'not much', due to typical levels of soil N after corn harvest.  (Table 2).

    Table 2.  Average soil nitrate N (0-30 cm depth) after corn harvest (without fall manure application) in 2 field surveys in the Lower Fraser Valley.  These nitrate amounts could be used by cover crops, if planted early enough.

    Year of SurveyPost-harvest nitrate N
    2005 (typical summer)75 kg N/ha (22 fields)
    2012 (hot and dry late summer76 kg N/ha (28 fields)

     

    Earlier cover crop establishment provides greater flexibility for responsible manure use.
