Advisories

  • Manure Spreading Advisory #2 for 2017: South Coast Region

    Date: Sept 5 2017

    • 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 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 neighbours.  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.

    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. 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.

    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.


    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

  • August UPDATE to Manure Spreading Advisory #1 of 2017: South Coast Region

    Date: Aug 1, 2017  
    Refer to Manure Spreading Advisory #1 of 2017 (April 3, 2017) for the current Advisory.  The following Update does not change the Advisory.

    This update will look at an aspect of the Right Rate – one of the 4R’s of nutrient management.  To know the nutrient value of what you apply, you need to know your spreader application rates.

    A reliable, quick method to calibrate your estimates is the following:

    1a. Drive the spreader over a series of pails/jars (liquid manure) OR…
    1b. Drive the spreader by a series of plastic sheets within the spread pattern (solid manure)

    2a. Measure the depth of liquid in each pail/jar. Average the depths. (liquid manure) OR…
    2b. Weigh the manure on the sheets. Average the weights. (solid manure)

    3a. Use the chart below to determine your application rates.

    The factsheet “Choosing and Calibrating Manure Application Equipment” has calculations to determine uniformity of application and travel speeds based on desired application rates.

  • JULY Update to Manure Spreading Advisory #1 of 2017: South Coast Region

    Date: July 6, 2017

    Refer to Manure Spreading Advisory #1 of 2017 (April 3, 2017) for the current Advisory. The following Update does not change the Advisory. Continue to use a minimum buffer distance of 5 meters from wet watercourses and ditches or 3 meters from dry watercourses and ditches during summer.

    Last month’s update related to the loss of nitrogen (N) from manure during warm weather and continues to be relevant throughout the summer.

    Manure Nutrient Composition
    Particularly during seasonal conditions where ammonia volatilization may be higher, it is important to remember that more nutrients than N are supplied with each manure application. Unlike N, these other nutrients are not volatilized, and their proportions relative to N will change if significant amounts of N are lost during application.

    Animal manures have more total phosphorus (P) per unit of total N compared to the P and N which a crop removes in a growing season. Using manure exclusively and repeatedly to meet crop N needs tends to result in over-fertilization of P, a nutrient of environmental concern in surface water.

  • JUNE Update to Manure Spreading Advisory #1 of 2017: South Coast Region

    Date: June 1, 2017

    Refer to Manure Spreading Advisory #1 of 2017 (April 3, 2017) for the current Advisory.

    The following Update does not change the Advisory. Considerations for spreading manure during warm weather With the onset of warm weather around the South Coast of BC 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. However, 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 ammonia N in your manure

    • Apply during the cooler times of day and when wind speeds are low
    • Incorporate the manure as soon as possible

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