April UPDATE to Manure Spreading Advisory #1 of 2018: South Coast Region

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,

Manure Spreading Advisory #1 for 2018: South Coast Region

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)

February UPDATE to Manure Spreading Advisory #3 of 2017: South Coast Region

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.
