Advisories

  • Manure Spreading Advisory #1 for 2015: South Coast Region

    Date: February 13, 2015

    It is acceptable to apply manure on established grasses, fields being seeded within two weeks of application, and berry fields if:

    • T-Sum value in your area is greater than 200*,
    • Soil temperature is greater than 5oC,
    • Crop is actively growing (for established crops only), and
    • Expected precipitation and manure applications will not create nutrient runoff to surface water or leaching below the root zone,
    • Nutrient loss risks are greatest on poorly-drained fields at this time.

    *Please see below for new guidance on interpreting your weather forecast.

    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.

    *T-Sum values as of February 12, 2015 in select locations:


              Abbotsford:  251
    Agassiz: 269
    Comox: 266                    
    North Cowichan: 265
    North Delta: 251               

    Please read the entire advisory for details and important information to assist in the decision-making process for manure application 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 and Fields Prior to Planting

    • Manure may be applied to a field of established grasses if all the following apply:
    1. T-Sum value in your area is greater than 200 (see http://www.farmwest.com/climate/tsum)
    2. Soil temperature is greater than 5oC measured at a soil depth of 10 cm
    3. Grass is actively growing
    4. A minimum buffer width of 8 meters (26 feet) is maintained between the application area and sensitive areas and watercourses including ditches
    5. *Less than 5 mm of cumulative rain is expected for the 48 hours following application*
    6. *Less than 10 mm of cumulative rain is expected for the 72 hours following application*
    7. 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

    *new guidance on interpreting your weather forecast

    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.

  • Feburary UPDATE to Manure Spreading Advisory #4 2014: South Coast Region

    Date: February 2, 2015

    In general, manure application on any crops is not advised.  Refer to Manure Spreading Advisory #4 of 2014 (Oct 23, 2014) and the previous Update (January 2, 2015) . We are monitoring weather, soil and crop conditions and will release the next Advisory as conditions improve.

    Planning to spread poultry manure (after conditions become appropriate)? Will you be able to spread uniformly and in a timely way? The spreading equipment and speed determine how effectively poultry litter (PL) is used as a replacement fertilizer (Fig. 1).

  • December UPDATE to Manure Spreading Advisory #4

    South Coast Region Date: December 1, 2014

    In general, manure application on any crops is not advised.

    Update your bookmarks: current and previous manure spreading releases (Advisories and Updates) are moving to a new BC Government webpage: http://bit.ly/1vPuMO7. For the next few months, the previous webpage will also work or redirect you to the new page. In addition, you can find the releases at www.farmwest.com and get them by subscribing to a mailing list* or by following BC Nutrient Manager (@BC_Agriculture) on Twitter.

    *Send an email to David.Poon@gov.bc.ca if you want to be included on the Ministry of Agriculture’s mailing list. Producer groups may also have their own mailing lists.

    Note: There was a typo in the November 3 Update. Whereas it was written that the next Advisory, expected to be released in 2015, would be “advising against further manure applications this fall and winter,” it should have been written that the next Advisory would be providing advice on careful manure application as conditions for manure spreading improve on some fields.

  • October UPDATE to Manure Spreading Advisory #3 2014: South Coast Region

    October 1, 2014

    It is not necessarily a good idea, or acceptable, for you to apply manure on your field just because a neighbour is applying manure. Refer to Manure Spreading Advisory #3 (September 2, 2014) to learn about the field-specific factors to consider before applying manure: Advisory #3

    Now is a good time to take another look at some things that could go wrong and address it in your farm’s contingency plan.

    • What is the plan to deal with severe weather (e.g. very wet fall) conditions that prevent manure spreading?
    • What should be done if a manure storage facility reaches capacity in the winter?
    • Who should be called in the case of a manure spill? (hint: 1-800-663-3456)

    Remember that field-stored solid agricultural wastes (except vegetation waste) must be covered by October 1.

    The next full Advisory, (advising against further manure applications this fall and winter) is expected to be released within the next 4 weeks.

  • August UPDATE to Manure Spreading Advisory #2 2014: South Coast Region

    Date: August 1, 2014

    • Plan ahead: There’s less risk of manure or nutrient loss with 2 light manure applications (1 now, 1 later) than with 1 heavy application closer to the rainy season.
    • Manure Spreading Advisory #2 (March 10, 2014) is still current: Adivsory #2

    July’s Update was about the imbalance of nitrogen (N) to phosphorus (P) in manure relative to crop requirements. One strategy to address the imbalance is to use mineral N fertilizer to fulfill part of the crop requirement. Advantages of mineral N fertilizer over manure include:

      • Particularly in cool and wet years, the N release from mineral fertilizer is more reliable
      • Application is more even, ensuring all parts of a field receive enough N
      • Unnecessary P additions can be avoided for soils with high amounts of soil test P

    But if manure application is reduced, where would the unused manure go?
    Scientists at Agassiz, BC have been looking at ways to answer this and better use the N and P in dairy manure (while reducing the need for starter phosphorus fertilizer).

     Evaluation of the concept on commercial farms is still in the early stages. Stay tuned.

    Assumptions used to estimate equivalent fertilizer nitrogen (N) amounts (see above)

    • Application of manure at 45,000 L per hectare (4,000 imperial gallons per acre)
    • Total N and ammonium (NH4) N contents on an as-received basis o Dairy, liquid (98% water): 0.13% N; 0.07% NH4-N o Dairy, slurry (94% water): 0.28% N; 0.15% NH4-N o Hog (96% water): 0.35% N; 0.26% NH4-N o Actual values vary from farm to farm
    • Ammonia (NH3) loss: percentage of NH4 lost to the air was estimated using the Ammonia Loss calculator (http://www.farmwest.com/climate/ammonia) with the following assumptions:: o Broadcast by splashplate with no incorporation, at an air temperature of 10°C and no wind o Dairy, liquid (98% water): 43% loss of NH4 o Dairy, slurry (94% water): 62% loss of NH4 o Hog (96% water): 49% loss of NH4
    • Mineralization: 25% of the organic N transforms into plant-available form in the year of application. In manure, organic N is Total N minus NH4-N. Additional notes
    • The above excludes the N value of manure in the 2nd and 3rd year after manure application. The N is temporarily stored in soil organic N and released in the 2nd and 3rd years.
    • The value of phosphorus (P) or potassium (K) in manure depends on P or K levels in the receiving soil: the greater the soil test P or K, the less is the value of the manure P or K in general.

    Do you know the nutrient content of your manure?

    • You can find a lab that will analyze your farm’s manure for total nutrient contents that will vary somewhat from the averages (Table 1). Find a list of laboratories here: http://goo.gl/ntuZqP
    • A fraction of the total nutrients has fertilizer value in the year of application, particularly in the case of nitrogen. Another fraction has fertilizer value in subsequent years. For general information about how large the fractions are, see Question 4 in the Q & A document here (http://goo.gl/rqdEjz).

    • 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.
