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 yeara highlighted 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.
Calibrations Using a Straight-Walled Pail/Jar
Calibrations using a 40 x 48 in. sheet
|Depth of manure in pail/jar||Application rate||Manure per sheet||Application rate|
* Tankers may be sold in US gallon capacity. 1 imperial gallon = 1.2 US gallons.
The factsheet "Choosing and Calibrating Manure Application Equipment" has calculations to determine uniformity of application and travel speeds based on desired application rates.
a 2014 Updates:
- Average nutrient contents of manure: April 1, 2014 Update.
- Nitrogen (N) fertilizer value ($) of dairy and hog manure: May 1, 2014 Update
- N fertilizer value ($) of chicken broiler and layer manure: June 2, 2014 Update
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.
