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 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 as of October 1. Please read the entire advisory for details and important information regarding manure applications.
Refer to Manure Spreading Advisory #2 of 2016 (April 4, 2016) for the current Advisory. The following Update does not change the Advisory. · Perennial grasses continue to benefit from fall manure applications when applied to meet crop nutrient needs. · When cropping after corn, cover crops or grassland planted after September 1 should not receive manure unless the need for nitrogen has been proven by a soil test. There is usually enough nitrogen remaining in the soil for a cover crop or newly seeded grass. · Manure applications on harvested or fallow fields are not recommended unless cover crops are planted and will become well established to uptake nutrients prior to the end of the growing season. · As the chances of wet and rainy conditions increase in September, guidelines for setbacks for manure spreading increase from 5 m (as per the current advisory) to 8 m from ditches or watercourses. · Plan manure applications to empty storage facilities before the rainy season
* 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.
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.
