Friday, October 31st • Pouliot Farm • 1:00-3:00 PM 1478 VT Route 128, Westford, VT 05494
See annual ryegrass, white clover and forage radish mixed right in with Urea and seeded at sidedress time in July. The Pouliots got a great catch, and now we can see how it survived the traffic during harvest, talk to the farmers about whether or not it competed with the corn, their herbicide program and see what they might change for next year. An added bonus…Tony will bring out the Great Plains twin-row corn planter.
Thursday, November 6th • Vorsteveld Farm • 1:00-3:00 PM 1/3 Mile East of Panton Village on Panton Rd.
The Vorstevelds welcome us back to get a look at the cover crops that have been growing since mid-August, see the results of manure injection and more. We’ll also see how their winter rye, winter wheat, oat, radish cover crop is doing that they seeded immediately after corn harvest…and how that cover crop did after manure was injected right after seeding. We can also talk to the Vorstevelds about their ‘minimum till’ system they have been using on their heavy clay soils.
Friday, November 7th • Clifford Farm • 1:00-3:00 PM 6147 VT Route 116, Starksboro, VT 05487
Check out results of two different cover crop studies – all in one field. See 10 different three-way cover crop mixes, each planted in July, August and September. We’ll also take a look at a research plots with winter rye drilled and broadcast, with and without Tillage Radish planted in mid-September. All of these plots also have portions with and without manure applications. We’ll also take a look at winter rye broadcast and rolled – per NRCS specifications.

Fall applied manure is often a subject of concern – for farmers, water quality advocates and even the general public. As you know, most farmers have the conundrum of having ideal field conditions for spreading manure in the fall (dry, open, great weather oftentimes) and a need for making sure they have adequate winter storage, but not wanting to lose out on the nutrients in that manure.. Especially producers who farm heavier soils with higher clay content, that try and avoid as much spring tillage as possible. If you are a no-till farmer, you know even better that fall applied manure without incorporation will not yield much of that nitrogen for you next year’s corn crop. You can lose up to 90% of your ammonium nitrogen with the right (or rather wrong) conditions.
So how do we make the most of fall applied manure… plant a cover crop, of course!! Fall applied manure as part of the establishment of a cover crop can be a win-win. Not only do you better utilize your manure, potentially doubling the amount of nitrogen retained, but your cover crop will perform better too. This all leads to better soil coverage, less erosion, better nutrient cycling, and lower fertilizer costs. Not a bad deal!
Last fall, we conducted a small demo/experiment at the Farm at VYCC in Richmond, Vt. Although this is not ‘scientific research’ per se, we did utilize a randomized split block design with three different treatments with and without manure. On October 2nd, we seeded 100 pounds of winter triticale per acre with different treatments of ‘Purple Bounty’ hairy vetch…either 10, 20 or 30 pounds per acre with the triticale. Five days later, liquid dairy manure was broadcast over half of all the plots at a rate of around 4,000 gallons per acre. We then measured percent cover one month later in November 2013 and then collected forage samples to analyze nutrient content, measured biomass, and re-measured percent cover on May 15th, right before the cover crop was plowed down. We found that the plots that received manure out performed those that didn’t in all aspects that were measured. Not surprisingly, a fertilized cover crop does better!! Plus you have better utilized your fall manure. The manured plots had double the biomass, double the nitrogen and phosphorus and potassium, and roughly one and half times the soil coverage in the fall and spring.
These plots have now been plowed down and were planted to ‘Early Riser’ corn (an 80 day flint/dent variety) on June 7th. No starter fertilizer was applied, and PSNT’s will be taken to make a recommendation for nitrogen later in the season.
There is more to come on this topic. This fall will be commencing a two year research project that will investigate combinations of winter rye and tillage radish (in comparison to straight winter rye) established with diary manure. We hope to determine if the addition of the radish in manured systems can amplify winter rye’s effectiveness as a winter cover crop. We also hope to determine the most effective seeding rates and establishment methods.

The growing season if finally starting to take hold. I have seen corn plants poking through the ground, vegetable crops starting to look like something edible, and first cut hay is on the ground in some places with hopes of a dry day to bale tomorrow. And with a new growing season comes all the hope and suspense of another year…all the potential for the best year ever or the worst, or maybe something in between. Farmers are going all out this week. We may not be able to predict what the weather will do this year, but one thing is for certain. Farmers in Vermont are innovative.
As I traveled from farm to farm today, I had the pleasure of talking with several different farmers – all of whom are trying something new this year. I saw fields of winter rye that were ‘planted green,’ that is no-till planted corn into standing rye before the cover crop was terminated. Innovation. I measured out 16 strips in a soon-to-be corn field with one farmer to help analyze two different reduced tillage systems this year. Innovation. He wants to interseed three different cover crops over those strips once the corn is up. Innovation. Another farm rounded out a SARE partnership project that analyzed two different cover crop mixes by no-till planting corn into those cover crops right next to a conventionally managed part of the field to see how these two systems will perform on his farm. Innovation. Another farm asked to borrow our GPS and try their hand at some precision agriculture. Innovation. A vegetable farmer is trying out different strategies to implement cover crops in his rotations for green manure, weed suppression, mulch and livestock forage. Innovation. A soybean grower has just modified his corn planter so he can no-till soybeans in 30-inch rows and will be trying out higher populations and some interseeded cover crops in those same soybeans. Innovation. I talked to three farms who have agreed to partner on a cover crop mixture demonstration project and will be hosting field days on their farms to share the results. Innovation. I have spoken with several farmers this week growing new crops like chicory, quinoa, and berseem clover. Innovation. I emailed with a new member of the Champlain Valley Farmer Coalition who is excited to be part of a farmer-based watershed group looking to protect Lake Champlain and thriving agriculture in Vermont. Innovation.
As you walk around your own farms, identify the many ways you are being innovative. As you drive down the road, what are your neighbor farmers doing to be innovative? If you see some fields this year that look a little different – instead of wondering if something went wrong, maybe its just another Vermont farmer trying something new.

Join us as we wrap up this year’s grazing season and think ahead to next year! Come hear how planned grazing can be fun and profitablee. Troy Bishopp, aka “The Grass Whisperer” is an accomplished grazier on his own farm in NY state, in addition to working with the Madison County Soil & Water Conservation District/Upper Susquehanna Coalition as their regional grazing specialist. Troy brings a holistic approach to grazing planning by helping farmers chart a course that pays attention to their personal goals as well as their profits. Julie Smith, UVM Extension Dairy Specialist, will also be here to discuss how to manage and troubleshoot common herd health issues including Johne’s, BVD, and nutritional deficiencies. Julie’s focus is on biosecurity and preventive animal health management. Hope to see you there!
This summer’s rainy, severe weather has had quite a negative effect on pasture quality. Visiting several grazing farms over the last month, we have seen that many dairy herds have been periodically housed and fed in the barn or barnyard in order to help preserve pasture stands, soil quality and animal health. In some cases, as with dairy heifers or beef cows, herds have been moved up on higher ground with somewhat better drainage, to help manage mud and decrease compaction issues. Some farmers have chosen to run their herds through tall stands of grass that may have otherwise been cut for hay. Although, animals will waste a lot of this lower quality mature forage, the upside is that what they trample will form a mat that can help reduce pasture damage.
However, even with these tactics, it has been challenging. Animal traffic on wet soils can cause soil compaction; pugging (holes) from hooves, leading to rough surfaces; areas of bare soil; potential runoff issues; and reduced plant density and yield. If despite your best efforts, your pastures are showing signs of this kind of damage, there are some basic things you can do now that some sunny weather is on the horizon and soils dry out a bit.
If pastures appear to have less plant density, using the UVM Extension no-till drill to plant new seed may be an option to bump up the diversity and species composition. There are numerous options for this depending on your goals, system, etc. One option would be to drill in grass species such as perennial ryegrass or orchard grass mixed with a legume such as Ladino clover. Another option would be to try an annual crop such as oats, triticale, or turnip for fall grazing. In some cases, it may be easiest to broadcast the seed and then turn the cows in to help stomp the seed into the ground.
For pastures that are severely pugged (also called ‘ankle breakers’) you may consider running a harrow to help smooth out the soil surface, and then planting your choice of seed. For large areas of bare soil that have developed extending from gates, water tubs and other heavy use areas, consider a crop like tillage radish. It can be seeded alone or mixed with a grass such as ryegrass and seeded at 10# per acre. Last year, we saw success seeding tillage radish into a heavy use area at this rate, yielding both nutritious tops that can be grazed after 45 days and large tap roots that help break up soil compaction.
To sign up to use the drill or to discuss seeding options to help amend summer pastures, producers are encouraged to call the Middlebury UVM Extension office at 388-4969.
Soon we’ll be coming up on the time of the summer where pastures really slow down and seem not to be growing at all. We are moving past the period of most rapid growth for our cool-season grasses (bluegrass, perennial ryegrass, and orchard grass, for example) and in late summer we’ll see that growth revive again. The thing about cool-season grasses is that they really slow down when the weather isn’t cool (surprise!). Longer rest periods for individual paddocks during this time can help prevent overgrazing damage, as plants will need longer (30+ days) before they will be ready to be grazed again.
One advanced management practice is to plant summer annual grasses such as millet. Unlike the cool-season perennials, warm-season annuals thrive when the temperatures rise. The optimal planting time for annuals such as millet is between June 1st and July 1st when soil temperatures reach at least 65 degrees. Unlike sorghum-sudangrass, millet does not carry the risks associated with prussic acid and it can tolerate wetter soils. It should be grazed at about 18 inches tall and can be grazed more than once.
Some farmers use millet when renovating pastures, plowing and then seeding down with millet for the season, before re-planting with a pasture mix in early fall. We know that farmers in other parts of Vermont have had success with this crop, but tilling up Addison County heavy clay soil in the window that is needed, can be a challenge. We are not sure how well it will do when drilled in to existing stands, but this summer we will be experimenting with no-tilling millet into perennial pastures on a handful of farms to see if we can get an increase in dry matter production in the late summer months. We are going to drill in a variety of pearl millet called ‘Wonderleaf’ as well as a mixture called ‘Summerfeast’ which contains both pearl millet and forage brassica. The idea being that the brassica plants will also provide some forage later into the grazing season. Stay tuned for some exciting results…

‘Double Cropping’ or the practice of harvesting two crops from the same field in one year is not a new concept by any means.However, as more and more farmers in the Champlain Valley are starting to look at cover crops as part of their crop rotation, it becomes a very viable option to evaluate harvesting them for forage.The most popular cover crop planted here in Vermont after corn silage is Winter Rye.Recently, however, we have started to see more and more farmers plant Winter Triticale (a cross between winter rye and winter wheat) for its purported value as a forage crop.This spring, several producers harvested winter rye and triticale for forage.We were able to collect forage samples in an attempt to compare them to each other and get a better sense of the overall value of these crops as forage.
We collected samples from three farms on five fields.The farms we collected samples from were located in Williston, North Ferrisburgh, and Wells, Vermont.The farms were harvesting these cover crops as baleage or grazing them.We calculated yields and sent the samples for analysis.Below is a table with our results, averaged by crop.The fields were all no-till drilled in late September at between 100 and 150 lbs/acre (after corn silage or into pasture) and harvested in mid-May.All of the crops were fertilized in the spring (with Urea or solid dairy manure).The majority of samples were taken at harvest during the split-boot stage (Feekes stage 10).The yield measurements represent one harvest, and do not account for multiple harvests.The pasture was grazed a second time in early June and that harvest would increase overall yields.
Overall, in our samples, triticale performed better than rye from a forage quality standpoint.Rye, however, outperforms in yields, sometimes by double.One of our triticale samples tested out at 22% protein when harvested at the split boot stage, but our samples averaged out at 17% CP.The rye was not far behind at 16% CP.We also found that planting at higher rates increased yields and quality.
In Alburgh, VT UVM Extension Agronomist, Dr. Heather Darby found similar results with her winter rye planting trials.She found similar dry matter yields over the 2011 and 2012 seasons.They did see lower crude protein levels at closer to 12% (our rye samples averaged 16% crude protein).
Aaron Gabriel, of Cornell Cooperative Extension’s Capital Area Agriculture and Horticulture Program also collected samples on four fields this May that were each planted to rye and triticale.Although they did not collect yield data, the protein levels were also lower than ours.Rye averaged 12.7% CP while triticale averaged 14.6% CP.Their relative feed values were very close to what we found…both crops averaging well over 100.
Like all crops, yield and quality all depend on management. Planting and harvesting in a timely manner, a good fertility program, and appropriate soils will have the most impact on growing a high quality, high yielding crop.In these situations, either crop would fit the bill.If you are hoping to get a crop off early in order to get your long season corn or soybeans established, winter rye might be a better fit.
Although dry matter yields are the best way to compare results, it is important to note that from a feed management standpoint, rye yielded up to 4 tons per acre of baleage (assuming 55% moisture) and closer to 5 tons/acre of chopped silage (assuming 65% moisture).Triticale yielded between around 2 tons/acre at 55% moisture and almost 3 tons/acre at 65% moisture.
For a cost of $35 per acre to seed these cover crops, a farmer can see a return of between $80 and $200 in feed value (depending on your yields).
Overall, triticale matures later than rye and is shorter with less biomass.It did test out as higher quality feed in our sampling, but was inconclusive
statistically. Rye does yield higher.In one field where rye was planted right next to triticale in the same field, the rye produced 1.49 DM tons per acre while the triticale yielded 0.91 DM tons per acre. In our observations, triticale seed is often more expensive and harder to get a hold of.Although, that may change as more producers purchase it over time.We found that seeding at higher rates closer to 150 pounds/acre gives higher yields and better quality (higher protein, lower NDF) than fields seeded at a lower rate of 100 pounds per acre.
An additional one or two dry matter tons per acre of quality feed is not a bad return on the investment of seed.Add to that the erosion prevention you accomplish over the winter and early spring, the nutrient recycling that occurs, and the soil health benefits of increased organic matter, better soil structure, and it seems like it makes sense in most cases.If you are unable to harvest these crops as forage and must plow or burn them down with herbicide, they can contribute significant amounts of nutrients back to your soil profile, enabling you to reduce fertilizer inputs.Rye provided 45 to 90 pounds of nitrogen, an average of 9 pounds of Phosphorus and 80 pounds of potassium; while triticale provided an between 45 and 65 pounds of nitrogen, 5.5 pounds of phosphorus, and 45 pounds of potassium (per acre).
All in all, a well-managed rye or triticale crop can improve soil health, water quality, and could become an important part of your feeding program.We will keep you posted as we continue to look at these cover crops in Vermont.
In early May, Dave Kennard at Wellscroft Farm and Fence Systems in Harrisville, NH hosted a fantastic full day workshop covering all aspects of livestock fencing. It was an information filled day with lots of helpful hints and tips on topics such as proper grounding, choosing the right sized energizer, locating it in the right spot, how to ensure lightning protection, and the latest and greatest types of fence and gates. There was really something for everyone, with a brush up on the basics as well as advanced tips to fine tune an existing system.
Here are the 6 most common mistakes with electric fence that Dave outlined for us that day:
1. Improper grounding: One thing that can help ensure your fence is well grounded is to have enough ground rods in place. The rods should be in a line and at least 10 feet apart. Galvanized rods are preferred. How many do you need? A rule of thumb is to figure 3-6’ of ground rod per joule of energizer. So a 3J energizer could require up to 18 feet of ground rods depending on soil moisture and fence resistance. Your ground field should be at least 40 feet away from utility grounds.
2. Having the wrong sized or type of energizer: Energizers are either 110 V plug-in, battery, or solar powered. Their effectiveness is measured in joules. The size of the area that is fenced, the type of animal, and type of fence used will determine what size energizer is needed. They increase from small 0.5 joule units to 50 joules or more (and so does the cost). Choose one based not just on where you’re at right now, but where you might be a few years down the road, so that you don’t ‘outgrow’ it and have to buy a new one. It is recommended to install the energizer outside of buildings in a protected three sided enclosure.
3. Improper livestock training: Since electric fence is a psychological fence, not a physical one, animals must learn to respect it, rather than run through it. Most livestock when shocked for the first time will instinctively back up. That is, except for pigs! They will keep charging ahead. For pigs, you’ll want to train them to electric fence inside an enclosed area (such as a barnyard) which will give them a physical barrier as well.
4. Improper lightning and surge protection: Lightning can cause a voltage surge and damage the energizer if the unit is a plug-in type. If unplugging the fence is not an option before a big storm, plugging the unit into a 1,000 joule surge protector can help reduce the impact if a nearby utility wire is hit. Also, lightning can damage an energizer if the fence or an object near the fence is struck. High voltage will be carried along the fence wire and through the energizer on its way to the ground. Lightning choke/diverters can be installed at the start of the fence. For areas of 5 acres or more, additional ones can be installed with their own ground rods. The surge protector and the diverter each cost less than $15. Not a bad insurance policy for a several hundred dollar energizer.
5. Not monitoring the voltage and condition of the fence: Use a volt meter or fence tester to monitor your voltage. If the fence is not adequately charged, you can start troubleshooting where the problem lies. Some volt meters are also fault finders and can point you in the direction of the problem – a definite timesaver! Monitor your fence for poor connections (snapping sounds) and keep excess vegetation off the fence which can ground it out.
6. Not choosing the right type of fence: How many strands of high tensile wire do you need on your perimeter fence? For beef, you might need 2 or 3 strands. For goats, maybe 50 wires would hold them in? Just kidding! For temporary fences when making subdivisions, a single strand of polywire can do the trick for dairy cows, while sheep and chickens do well with electric netting.
Keeping these tips in mind can help minimize problems and keep both the animals and the people happy during the grazing season.
