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 yearhighlighted 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:

May UPDATE to Manure Spreading Advisory #2 2015: South Coast Region

Manure applications have an overall positive effect on soil biology. Many of the same creatures that live in soil can be found in manure: shredders (arthropods), decomposers (bacteria and fungi), and grazers and predators (nematodes and protozoa). With excessive applications of liquid manure, there can be negative effects on soil biology: increased saturation of the soil, creating anaerobic conditions that increase rates of greenhouse gas emissions (nitrous oxide and methane), and decreasing soil life.

Manure Spreading Advisory #2 for 2015: South Coast Region

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. Please read the entire advisory for details and important information to assist in the decision-making process for manure application(s) and storage.
