  • 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.

     

    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 Regulationand the Environmental Management Act.

  • 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.

    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.

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

    Date: May 3, 2018

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

    From the current Advisory:

    Well planned manure applications are acceptable on most fields that are seeded, will be seeded within two weeks, and/or well-established grasses.”

     The Canada Good Agricultural Practices outline how to apply manure to food crops and minimizes risk from pathogens:

    • Incorporate manure into the soil within 24 hours to minimize contamination to adjacent crops from wind drift or run-off. 
    • Take precautions when using untreated or partially treated manure (for example, aged) on fruits and vegetables that can be consumed raw or with minimal processing. For example:
      • For crops that are not eaten raw or where the manure does not come into contact with the edible part: apply manure when the time between application and harvest is greater than three months.
      • For crops that can be eaten raw and where the manure can come into contact with the edible part: apply manure when the time between application and harvest is greater than four months.
      • In non-fruiting years for perennial crops: apply manure when the application is not in the year of harvest.

    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.

    Refer to Manure Spreading Advisory #1 of 2018 (Mar 16, 2018) for the current Advisory
     
    From the current Advisory:
    “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 5°C, and
    • Crop is actively growing (for established crops only)”
     
    Manure provides valuable nutrients for crops, but only if it stays in the field.  
    • Check the weather before spreading to ensure there is not increased risk of runoff.
    • If the forecast calls for more than 12 mm of rain in the 3 days following application, the risk of runoff over land or transport of the applied manure through drainage tiles is increased.

    Date: Mar 1, 2018

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

     “in general, manure application on any crops is not advised.” 

    The following Update does not change the Advisory. 

    With the T-sum value hovering near 200 in several areas across the Fraser Valley, it is important to remember the other factors to consider before a forage field is suitable for spreading manure. 

    • The field is not frozen or saturated; subject to flooding or runoff; and is not tile drained with the potential for manure to leave the farm;
    • Soil temperature should be greater than 5oC measured at a soil depth of 10 cm;
    • Grass is actively growing or;
    • A minimum buffer width of 5 meters (16 feet) is maintained between the application area and sensitive areas and watercourses including ditches;
    • Less than 10 mm of accumulated precipitation is expected for the 5 days following application.

    Most fields in the Fraser Valley do not meet these conditions, therefore there is no change to the current advisory.

    A full Advisory may be issued mid March if conditions change.

    Date: Feb 2, 2018
    Refer to Manure Spreading Advisory #3 of 2017 (Nov 1, 2017) for the current Advisory: “in general, manure application on any crops is not advised.”

    The following Update does not change the Advisory.

    The T-Sum is one factor used to determine appropriate timing for the first manure application on grass fields. More importantly, however, decisions about the first manure application should consider the overall risks of runoff from the field, not just the state of the grasses. On some but not all fields, conditions will be suitable for manure application before T-Sum reaches 200. On other fields, conditions will not be suitable even after T-Sum reaches 200 (e.g. if fields are still saturated from rains).

    T-Sum values, a sum of daily mean temperatures above 0°C, for the region are listed below and compared with values for the same time last year and the historical average.

    Date: Dec 4, 2017

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

    “in general, manure application on any crops is not advised.”

    The following Update does not change the Advisory.

    During the time of year when manure applications are not advised, thoughts turn to manure storage. Adequate manure storage on the farm allows for manure to be applied when it will provide the best nutrient contribution to crops.

    In most regions of B.C., 180 - 200 days should be considered as a minimum amount of time that manure will need to be stored. To assess your current storage or to support any decision to expand your herd it is helpful to determine a total manure storage capacity. This should consider animal numbers, manure handling, contribution of other waste or water to manure, and the desired storage period.

    The B.C. Ministry of Agriculture has a factsheet “Sizing Dairy Manure Storage Structures” to help determine storage capacity.
