First Cutting Updates - Week of May 2, 2016
Betsy Hicks, Area Dairy Specialist
South Central New York Dairy & Field Crops
The SCNY team has started to monitor alfalfa heights again this spring to help predict quality and %NDF for first cutting hay crop. Alfalfa height has been proven to be a reliable indicator of NDF values in the field for alfalfa, alfalfa/grass mixed and all grass stands. Results are compiled and emailed on a weekly basis - please feel free to forward the results! If your area falls outside of our 5 county region, please contact Betsy (bjh246@cornell.edu) because there are many other counties that are participating in the weekly checks. The weekly email for the month of May has a table of the locations around the region where we have measured the alfalfa height, as well as the elevation. Even if your fields aren't measured, you can use the location and elevation as a guide to conditions that may be similar to your own.
Even though the spring has slowly been coming along, those in the more southern areas are seeing alfalfa heights that are approaching 11-12" already. This could mean, with a drink of rain and a little heat, that pure grass fields in those areas are gaining maturity faster than we think! Many of the fields in the northern counties have alfalfa and grass that will come on fast with a little heat and rain also. If you haven't had a chance to check out your fields, take advantage of rainy weather that is going to come and scout your fields to see how your alfalfa wintered. Janice and Betsy are always willing to check out fields, so don't hesitate to call us. Many of the locations in the table read "Too early" - the predictor for date to cut doesn't kick in until alfalfa height reaches 10 inches, so watch for our email next week to see how the heights have progressed.
The numbers that are indicators for using alfalfa heights for NDF content are as follows:
• 100% grass stands should be cut when nearby alfalfa is 14 inches tall, to achieve 50% NDF
• 50/50 mixed alfalfa/grass stands should be cut when nearby alfalfa is 22 inches tall, to achieve 44% NDF
• 100% alfalfa stands should be cut when alfalfa is 28 inches tall, to achieve 40% NDF
Predicted days to cut are based on daily NDF increases for grasses of 1.0% point, 50/50 mixed alfalfa/grass stands of 0.8% points, and alfalfa of 0.5% points and are adjusted for the coming week's weather. Typically NDF increases about 0.8 to 1.2 per day for grasses, with cooler weather being the lower end of the range and warmer weather being the higher end. For alfalfa, NDF increases about 0.4 to 0.7 per day, also dependent upon warm/cool weather.

ON FARM RESEARCH TRIALS 2025: Value of Manure & Power of Manure
Manure has all seventeen essential plant nutrients and can increase yield beyond what can be obtained with fertilizer only. In this project, Value of Manure, we evaluate the nitrogen fertilizer replacement value (how much N can we credit to manure?) and yield differences as a result of manure application.Farm Participants Needed for Bale Grazing Grant!
Information on the Project:- Approximately 10 acres total needed to bale graze two different bale densities
- "Core" farms will graze two winters, "Demo" farms will graze one winter.
- Payments for both "Core" farms and "Demo" farms
- Baseline soil sampling by bale grazing team
- Forage measurements in early season by bale grazing team
- Late season clipping if residual not trampled down by farm

2018 Drug Residue Prevention Manual
For more than 30 years, the U.S. dairy industry has focused educational efforts on the judicious use of antibiotics through the annual publication of a Best Practices Manual. The 2018 edition of the National Dairy FARM Program: Farmers Assuring Responsible Management? Milk and Dairy Beef Drug Residue Prevention Manual is the primary educational tool for dairy farm managers throughout the country on the judicious and responsible use of antibiotics, including avoidance of drug residues in milk and meat.The manual is a quick resource to review those antibiotics approved for dairy animals and can also be used as an educational tool and resource for farm managers as they develop on-farm best management practices necessary to avoid milk and meat residues. Visit the Manual and Form Library to download copies of this important tool!
