New York State Weekly Weather Outlook – July 3, 2014

From Jessica Spaccio, NOAA Northeast Regional Climate Center, Cornell University

Last week temperatures ranged from normal to 4 degrees above normal.  Most areas received one to three inches of precipitation; a few areas had half an inch to one inch while isolated areas had over three inches.  Base 50 growing degree-days ranged from 100 to 180.

Heavy rain and severe storms possible today, then clearing for a nice holiday weekend.  Work-week brings next chance for showers.

Today will be cloudy with showers and thunderstorms associated with a cold front moving across the state; some storms could be severe; also potential for heavy rainfall as the front stalls and added moisture from Tropical Storm Arthur.  Highs will be in the mid 70’s to mid 80’s, with warmer temperatures in the southeast portion of the state.  Lows will be in the upper 50’s to mid 60’s.

Friday a few remaining showers will exit the state and leave sunny skies with less humid conditions.  Highs will be in the mid to upper 70’s.  Overnight lows will be in the upper 40’s to upper 50’s.

Saturday will be sunny with highs in the mid 70’s to low 80’s.  Overnight lows will be throughout the 50’s.

Sunday will be another dry, sunny day with highs in the upper 70’s to mid 80’s.  Lows will be in the upper 50’s to mid 60’s.

Monday will be partly sunny with a chance of scattered showers and thunderstorms and highs in the mid to upper 80’s.  Overnight temperatures will be in the mid to upper 60’s.

Tuesday will be partly cloudy with a chance of scattered showers and thunderstorms and highs in the low to mid 80’s.  Lows will be in the mid to upper 60’s.

Wednesday’s highs will be in the upper 70’s to mid 80’s with scattered showers and thunderstorms possible.  Lows will be in the low ti mid 60’s.

The five-day precipitation amounts will range from 1/10 to 1 1/2”; 7-day amounts will range from ½ to 2” with higher amounts for both periods being in southeast NY.

The 8-14 day outlook (July 10-16) is showing above normal temperatures and above normal precipitation.

Fusarium Head Blight Alert – June 26, 2014

From Gary Bergstrom, Extension Plant Pathologist, Cornell University

Most, but not all, spring barley and wheat fields in New York State are now past the flowering and early post-flowering stages.  This week remains critical for farmers making fungicide spray decisions for suppression of Fusarium head blight (FHB) and protection of flag leaves from foliar diseases in late flowering spring cereals.  The triazole products Caramba and Prosaro are the most effective fungicides for suppression of FHB and deoxynivalenol (DON) toxin contamination when applied at wheat flowering (emergence of anthers on heads) or at full head emergence in barley (anthers begin to appear on barley before heads emerge from the boot).  A flowering application of triazole fungicide should be based on Fusarium head blight (FHB) risk as well as the risks of powdery mildew, rust, and fungal leaf blotches in the upper canopy based on scouting of individual fields.  There is an application window of approximately 5-6 days from the beginning of flowering in which reasonable FHB suppression can be expected.  Fungicide products containing strobilurins should not be applied to headed wheat or barley as they may result in increased levels of DON in grain. The current risk of FHB epidemics is low to moderate for spring wheat and barley over much of the state but precipitation patterns have been highly variable across the state.  Check the Fusarium Risk Assessment Tool (http://www.wheatscab.psu.edu/) and your local weather forecast frequently as your crop approaches flowering.  This is an excellent time to scout your winter cereal fields to assess FHB incidence and to identify fields that may be at higher risk for DON toxin contamination.

Double Cropping Research Helps Northern NY Dairy Farmers

Double Cropping Research Helps Northern NY Dairy Farmers

Northern New York – Research conducted on Northern New York farms by Cornell University researchers with funding from the farmer-driven Northern New York Agricultural Development Program (NNYADP) is helping farmers enhance their production of forage crops for their dairy cows.

Eight farms in Northern New York participated in on-farm double cropping trials from 2011 to 2013. The research specifically refines nitrogen fertilizer management guidelines for fields that will be used for double cropping – the practice of planting two different crops on the same field in which the second crop is planted after the first has been harvested.

By using the same land to plant two crops that can be fed to dairy cows, farmers can offset previous-year dairy cow forage inventory losses due to drought, excess water, or other causes.

Growing winter cereal crops, such as cereal rye, triticale or wheat in a double-cropping system can also help with on-farm manure use, reduction of nutrient loss to the environment, and increased production per acre.

The complete report of the NNYADP double-cropping nitrogen management trials titled Winter Forage Small Grains to Boost Feed Supply: Not a Cover Crop Anymore is now posted at www.nnyagdev.org.

Profiles on growing 70 acres of triticale as a double crop with corn at Brandy View Farm in Madrid, NY, and a cereal rye trial at BCS Dairy in Peru, NY, are also posted on the NNYADP website.

The Northern New York Agricultural Development Program is a small grants research and technical assistance program helping farmers in Clinton, Essex, Franklin, Jefferson, Lewis and St. Lawrence counties. The NNYADP receives funding through the New York State Legislature.

MORE INFORMATION
‘Our research platform addresses a primary question identified by Northern New York (NNY) farmers, that is, how to manage nitrogen application for double-cropping, particularly at dormancy break in the spring,’ says project leader and Cornell Nutrition Management Spear Program Director Dr. Quirine M. Ketterings.

The objective of the ongoing NNYADP-funded research is to calibrate the most precise optimal nitrogen application rate to achieve high-yield, high-quality crops in a double-cropping system. More precise N application may reduce production costs as well as the environmental loss of nitrogen not taken up by the crops.

Project results to-date include data from seven trials conducted on farms in Northern NY and more than two dozen other farms statewide. In 2013, forage yield of double crops averaged 2 tons/acre statewide and 1.8 tons/acre in NNY.

Soil fertility and the need for nitrogen varied widely by site in the NNY trials, e.g, three sites of the seven NNY sites showed no yield response to additional applied N while three others needed 75 to 90 lbs. N/acre to reach optimum yield.

This research continues in NNY and statewide in 2014 to determine how planting date, manure application history, soil type and other factors might impact the differences in yield, in crude protein content of the crops, and optimum N rates across the different sites.

An additional NNYADP-funded field trial compared cereal rye, oats and radishes planted as cover crops at Thunder Lane Dairy in Lewis County.

The results of the trials at Thunder Lane Dairy indicated that radishes had the greatest root, shoot, and total biomass accumulation of the three species, but nitrogen accumulation was limited to 28 lbs. N/acre by radishes vs. 17 lbs/acre for cereal rye, and 11 lbs. N/acre for oats. However, because radishes and oats typically winterkill in Northern New York and will not accumulate more N into the spring season, cereal rye becomes the more feasible choice. Cereal rye typically overwinters and accumulates additional biomass in the spring, typically averaging 1.5 times the total N accumulated in the fall, based on field assessment over the past several years.

Northern New York producers and NNYADP committee members are now interested in answering the questions: What are the costs and benefits associated with incorporating double crops into cropping systems, and what yield levels are needed to ensure that the adoption of double crops will be a profitable change for farms in the northern region of New York State.

In addition to the regional farmers, NNY double-cropping project collaborators include the Cornell PRO-Dairy Program, Cornell Cooperative Extension, the Lowville Farmers Co-op, and independent crop consultants.

New York State Weekly Weather Outlook – June 26, 2014

From Jessica Spaccio, NOAA Northeast Regional Climate Center, Cornell University

Last week temperatures ranged from 0 to 2 degrees below normal for most of the state. Precipitation amounts ranged from less than a quarter inch to over an inch (not including Wednesday’s heavy rain).  Base 50 growing degree-days ranged from 60 to 140.

Cloudy day today as the rain moves out and leaves us with a nice and sunny weekend.  Warm and humid weather with scattered showers and thunderstorms into the workweek.

Today the rain will slowly move east and out of the state but skies will remain mostly cloudy.  Highs will be in the mid 70’s to low 80’s.  Overnight temperatures will range from mid 50’s to low 60’s.

Friday will clear up with mostly sunny skies and temperatures in the low to mid 80’s.  A few scattered showers can’t be ruled out, but any that do occur will be very light.  Overnight temperatures will range from mid 50’s to low 60’s.

Saturday will be sunny with highs in the low to mid 80’s.  Overnight lows will be in the 60’s.

Sunday will be partly sunny with highs throughout the 80’s and slight chances for showers and thunderstorms, more likely in western NY.  Lows will be in the mid to upper 60’s.

Monday will be partly cloudy with a chance of scattered showers and thunderstorms and highs throughout the 80’s.  Overnight temperatures will be in the mid 60’s to low 70’s.

Tuesday will be partly cloudy with a chance of scattered showers and thunderstorms and highs throughout the 80’s.  Overnight temperatures will be in the mid 60’s to low 70’s.

Wednesday’s highs will be in the low to mid 80’s, again with scattered showers and thunderstorms possible. Overnight temperatures will be in the mid 60’s to low 70’s.

The five-day precipitation amounts will range from 1/10” to ½” ; 7-day amounts will range from ½” to 1 ½”.

The 8-14 day outlook (July 3 – 9) is showing above normal temperatures and above normal precipitation.

Late Planting and Forage Inventories

From Jeff Miller, Ag Program Leader of the Cornell Cooperative Extension Oneida County

If you have ground that you worked up to plant corn but didn’t yet…. You may want to consider brown mid rib sorghum sudangrass because it can produce better in hot dry conditions that are usually associated with this time of year.

Irregardless, if you think that corn silage yields may be less than normal and you may not have the inventory that you need for your livestock what things can you do :

·         Contract some acres of corn  from local grain producer
·         Apply appropriate side dress N to push yields on early planted corn
·         Apply up to 75lbs of N after each cut of productive grass fields
·         Forward contract corn grain
·         Culling of less productive livestock
·         Sale of heifers if they are not needed as replacements
