We have begun monitoring of 1st cutting for quality this year. If you are not familiar with our procedures we use alfalfa height to predict Neutral Detergent Fiber (NDF) for alfalfa, alfalfa/grass mixed and grass stands. Alfalfa height has proven to be a reliable indicator of NDF values in the field.
Here are numbers that are helpful when using alfalfa and grass height as an indicator of NDF content:
In general we say 100% grass stands should be cut when nearby alfalfa is 14 inches tall to achieve the desired 50% NDF.
Begin cutting 50/50 mixed alfalfa and grass stands when nearby alfalfa is 22 inches tall for the desired 44% NDF.
Begin cutting 100% alfalfa stands when alfalfa is 28 inches tall for the desired 40% NDF.
The desired NDF for all grass fields is 50%, 50/50 mixed alfalfa and grass fields is 44%, and pure alfalfa stands is 40%. Predicted days to cut are based on daily NDF increases for grasses of 1% point, 50/50 mixed stands of .8% points and alfalfa of .5% point. Typically NDF increases about 0.8 to 1.2/day for grasses expecting the lower end of that range in cooler weather and the higher end in warm. Alfalfa NDF increases about 0.4 to 0.7/day again figuring the lower end of that range with cool temperatures and the higher in warm. Predictions are adjusted for the coming week's weather and right now we are assuming normal growth.
In the attached tables locations around the region are listed where we have measured alfalfa height. You can use the location and elevation as a guide to conditions that may be similar to your own.
For May 9 growth has slowed considerably given the cold temperatures of the past week. On average alfalfa only gained 3 inches, which given the delay in field work due to cold rainy weather, is a good thing. There may be opportunities to harvest for quality given current weather predictions for the next two weeks. Start a list prioritizing which of your fields have a chance for highest quality and those that are past prime or are likely to be too wet to harvest without rutting up fields or worse.
At some of our locations fields are past for grass harvest and are at or approaching time for alfalfa grass mixes to be harvested. Check your fields so you know what stage your haycrop is in.

As always use information in the attached table as a guide to know when to harvest by checking your fields! Next report May 16!

Cash Rent and Custom Harvest Survey
To date, there is limited information available about rental rates and fees for crop harvesting. Farms can use this valuable information for their farm business planning to help improve decision making and profitability.The data that is collected, and the subsequent reports/findings/resources will be helpful for all of us to answer that call of "What's the average rental rate in my area?" and "How much do people charge to combine oats?"
Farmers Can Join MeatSuite For Free!
MeatSuite.com is a free resource provided by Cornell University where NY meat farmers can create a farm profile and list their bulk (wholes, halves, quarters) and bundled (i.e. Grilling Bundle) meat products.Why should farmers join?
1. It's free and easy!
2. Connect with more local customers. In the past year the MeatSuite.com farm directory had 8,300 visits from New York consumers. Farm profiles get as many as 25 views per month from potential local customers. We also spotlight MeatSuite farms on social media and bring attention and purchases to farms through highlights and giveaways.
How do I join?
Farmers can visit https://www.meatsuite.com/farmers/ to create a free farm profile. You must list at least one product for your farm's profile to go live. You'll also have access to Cornell's free Meat Price Calculator, a helpful tool for pricing your meat to make a profit.
While you're on MeatSuite, check out the "Creating Consumer-Friendly Bulk Meats" publication on the log-in page. It has tips on how to create bulk meat products that are easier for first-time buyers to say "yes" to.
If you have any questions as you create your farm profile or products, we're here to help! Please email Matt LeRoux at mnl28@cornell.edu.
