October UPDATE to Manure Spreading Advisory #3 2015: South Coast Region

Refer to Manure Spreading Advisory #3 of 2015 (September 1, 2015) for the current Advisory.  The following Update does not change the Advisory.

“Manure application on perennial grasses is usually appropriate as long as crop growth and warmer weather patterns (greater than 5°C) continue; fields are trafficable; and precipitation does not create runoff” (Manure Spreading Advisory #3 of 2015).

Manure Spreading Advisory #3 for 2015: South Coast Region

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.

August UPDATE to Manure Spreading Advisory #2

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

When balancing the goal of maximizing corn yields with the goal of establishing cover crops, consider the effect of cover crop planting date (Table 1).

Table 1.  Nitrogen uptake by cover crops decreases with later planting dates.  Values are for B.C. South Coast.  Actual uptake depends on crop variety and other factors.
