  • July UPDATE to Manure Spreading Advisory #2 2015: South Coast Region

    Date: July 2, 2015

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

    The Manure Spreading Updates of last yearhighlighted the nitrogen (N) fertilizer value of manures.  To know the N value of what you apply, you need to know your application rates.  You might estimate the rates by counting the number of loads applied.  A more 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.

    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.

  • June UPDATE to Manure Spreading Advisory #2 2015: South Coast Region

    Date: June 1, 2015

    Refer to Manure Spreading Advisory #2 of 2015 (April 1, 2015) for the current Advisory (Advisory #2). The following Update does not change the Advisory.

    Should farmers sidedress nitrogen fertilizer on their corn fields this year?

    • If the soil nitrate-nitrogen (NO3-N) in the top 30 cm at the 6-leaf stage of corn (i.e. presidedress nitrate test or PSNT) is greater than 30 parts per million (ppm), there is likely no economic benefit to the sidedress application*.
    • A history of annual manure application on a field is a good indicator that the field will have greater than 30 ppm soil NO3-N (0-30 cm) in south coastal BC, because the manure supplies the soil with nitrogen that is converted to nitrate for years after application under favourable conditions (warm and moist but not too wet or too dry).
    • There has been minimal precipitation to leach nitrate from the root zone this past month. In May 2015, the Abbotsford airport recorded 8.6 mm of rain, whereas the 1981-2010 average was 99.8 mm. Thus, many farmers are able to avoid sidedress nitrogen fertilizer applications, as they have been doing for many years now. *Spring nitrogen tests. http://www.farmwest.com/node/944

  • May UPDATE to Manure Spreading Advisory #2 2015: South Coast Region

    Date: May 1, 2015

    Refer to Manure Spreading Advisory #2 of 2015 (April 1, 2015) for the current Advisory. The following Update does not change the Advisory.

    Manure applications have an overall positive effect on soil biology. Many of the same creatures that live in soil can be found in manure: shredders (arthropods), decomposers (bacteria and fungi), and grazers and predators (nematodes and protozoa).

    With excessive applications of liquid manure, there can be negative effects on soil biology: increased saturation of the soil, creating anaerobic conditions that increase rates of greenhouse gas emissions (nitrous oxide and methane), and decreasing soil life.

    To promote positive effects of manure application on soil biology:

    • Apply at rates to meet or approach crop requirements
    • Spread manure evenly or apply more on areas requiring remediation (e.g. solid manure on eroded knolls)
    • Use application methods to minimize soil surface disturbance

  • Manure Spreading Advisory #2 for 2015: South Coast Region

    Date: April 1, 2015

    • 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.

    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.
