SPRING BUS TOUR SENSATION; CAN ROLLING-CRIMPING HELP MANAGE COVER CROPS?

By Nate Severy, Agronomy Outreach Professional

On June 13, UVM Extension and the Champlain Valley Farmer Coalition
teamed up to host a bus tour to six farms throughout Addison and Chittenden Counties highlighting spring conservation practices. The tour showcased manure injection, cover crop and no-till systems, pasture management, and nutrient management on dairy and vegetable farms. It was a long, information-packed day. One of the most amazing things was that all of the host farms had the same general message: they care about our environment, and are working hard, taking risks, and investing a lot of time and money to try to be the best farmers they can.

One tour participant commented that they were flooded with information and hadn’t realized just how much farmers are standing up and taking a leadership role to protect water quality. The event was a great example of how farmer organizations and UVM Extension can work together to support the agricultural backbone of Vermont.

One of the demonstration projects on the bus tour was a trial of rolling-crimping a winter rye cover crop, using farm built equipment. Rolling-crimping works best on a more mature cover crop, which may be useful in a spring like this one if winter rye becomes thick and tall because spring rains prevent termination. Rolling-crimping also helps facilitate the
mulching effect of the cover crop and, with correct furrow adjustment, should address issues of light penetration to young seedlings.

Separately, Jeff Sanders, from UVM Extension Northwest Crops
and Soils, received a grant to purchase and demo a planter-
mounted roller-crimper. This is actually a shield and two disks on the front of each planter unit, as opposed to a single roller-crimper. These attachments are angled to part the cover crop material and roll it away from the furrow where the corn is planted.

No-till corn planted into tall winter rye cover crop in Addison County clay soil using the UVM planter with Dawn roller-crimper attachments on the front of each planter unit.

We used this technology on two Addison County farms totaling around 50 acres. After 4 hours of adjusting the planter, we were successfully rolling-crimping! One farm field had manure injected several inches below the surface a month before planting and another field had large scale
cover crop trials. When compared to a regular no-till field, which can
look chaotic, there is a very satisfying symmetry when the field
is roller-crimped.

However, we had some setbacks while  planting. There was so much residue that every few acres we had to stop and clean the closing wheels because at least one would plug with winter rye. Specific closing wheels seemed to be plugging more often, and we will have to investigate that further. We also had issues getting adequate down pressure to crimp the rye stalks properly; this may not be an issue with a heavier corn
planter.

We will monitor the fields over the next few months, observing changes in water infiltration/retention and drought stress response, weed and pest levels, nitrogen availability, and corn yield.

Thanks to Jeff Sanders and the participating farmers! We look forward to sharing results and to future trials.

EXPECT TO APPLY NITROGEN DUE TO THE WET WEATHER

By Rico Balzano, Agronomy Outreach Professional

Spring 2017 started relatively dry, but Mother Nature has certainly made up for it, with above average rainfall in May, and the seventh wettest June in 100 years (National Weather Service, Burlington, VT).

Applying nitrogen to corn, a process known as side-dressing.

While this spring’s rainfall may average out to be normal, the timing of it has caused some problems. Rain started to increase just as corn planting season began, keeping soils cold and postponing planting. Cold soils delayed emergence and slowed growth in planted fields. More to the point, nitrogen fertilizer that was applied pre-plant or at planting time has seen extremely susceptible to loss. Nitrogen is lost through denitrification in saturated soils, and is lost through leaching in well-drained soils. Either way, nitrogen is often not there when the corn needs it. This will prompt many farmers to think about applying nitrogen to corn while it is growing, a technique known as sidedressing, which is a more efficient

use of nitrogen, especially on soils prone to leaching.

The good news is that the organic nitrogen in manure has been slow to mineralize because of the cool temperatures and will still be there as the season progresses. However, it is safe to say many farms will be sidedressing corn with extra nitrogen this year.

Pre-sidedress nitrogen test samples at the UVM
Agricultural and Environmental Testing Lab.

The old, reliable way to predict how much sidedress nitrogen to apply is the pre-sidedress nitrogen test (PSNT). PSNTs are simple and affordable ($6-8). However, they require effort and only offer a snapshot in time; they do not account for previous activity nor for future nitrogen mineralization.

An alternative way to generate sidedress recommendations is Adapt-N software. Nitrogen is very dynamic in the soil so it is difficult to predict how much will be plant-available. Therefore, it is necessary to have as much information as possible about fertilizer, manure, previous crop and soil type to generate a good recommendation with Adapt-N. You can also assess the nitrogen needs of corn using chlorophyll meters, active sensors and aerial imagery. These can be effective when used properly, and local agricultural consultants can provide these services.

PSNT is recommended for corn fields 2 or more years after a sod, and/or where manure rate is uncertain, or if manure application is not expected to meet corn N requirement. PSNT is not recommended in first-year corn after a grass sod; first-year corn after an alfalfa grass stand is plowed down; or if enough manure was applied to meet corn N requirement.
Below are the PSNT sampling guidelines, a link to the UVM sample submission form, and the updated UVM nitrogen recommendations
based on PSNT results. Results are usually sent out within 24 hours since the information is time-sensitive.

PSNT Sampling Guidelines:
1. Wait 2-3 days after significant rainfall (due to nitrate
leaching).
2. Sample when corn is 6-12” tall and sample to a depth of
12” – deeper than a regular soil test.
3. Take 15-20 cores per field from in between rows to avoid
fertilizer bands. Mix sample thoroughly.
4. Air dry samples ASAP to stop further mineralization.
5. Submit samples in small plastic bag (about 1 cup).

THINK SPRING WHEN PLANTING COVER CROPS

By Kirsten Workman, Agronomy Outreach Professional

Farmers are planting cover crops at a rapidly increasing rate across Vermont – and for good reasons. The water quality and soil health benefits of this farming practice are undeniable. However, a farmer who manages that cover crop in a spring like this one will attest to the added complexity cover crops bring to the challenges of growing annual crops in Vermont.

Through our work with many innovative producers in the Champlain Valley, we identified the need to think about planting cover crops differently. We should not only ask questions about how late we can plant or how to get the most biomass possible, but can we take a more nuanced approach to decision making? In order to use cover crops as a management tool, a farmer should first decide on the goal for that cover
crop, and then implement a plan to accomplish that goal.

The main goal is usually to reduce erosion and nutrient loss. However, are you also trying to reduce weed pressure, decrease nitrogen applications for the subsequent crop? Will you be interseeding into a standing crop? Do you want to maximize spring biomass either to harvest it as forage or to use a rollercrimper device? Or, maybe you hope to minimize spring biomass to ease spring field management without sacrificing erosion control and nutrient retention.

The latter example is one goal we have heard from many producers who value the role cover crops play in reducing soil and nutrient loss in the sensitive fall and early spring seasons, but who don’t want so much biomass to deal with in the spring when it’s time to plant annual
crops, especially on heavier soils.

Borrowing an idea from one such farm, last fall we planted cover crop plots on nine farms, from Westford to Pawlet, on sandy loam to clay soils. Our goal was to determine the “magic” combination of seeding rates for planting winter rye and spring oats in the fall to maximize fall performance, while minimizing spring biomass. The dry fall and wet spring thwarted some of our efforts, but we were able to collect data at six locations. We don’t have the final answer yet, as one year doesn’t tell the whole story. However, we found that all combinations did comparably
well at providing at least 30% ground cover to protect from erosion in the fall. With the exception of the all-oat plots, all combinations increased soil cover and biomass from fall to spring.

Winter rye (left) and winter-killed oat (right) cover crop plots at Pouliot Farm in Essex on May 1, 2017.

This trial supported previous observations that winter rye – planted with a grain drill – provides similarly high biomass in the spring at different seeding rates, down to 45 pounds per acre. The two combinations that seemed to maximize fall performance and spring soil coverage while minimizing spring biomass were 30 pounds of rye with 45 pounds of oats, and 15 pounds of rye with 60 pounds of oats. The lowest rate of rye is probably not an advisable rate on steep ground, but it should provide enough soil coverage on flat ground.

Our aim is to help farmers identify the pros and cons of different methods of cover cropping, and evaluate which methods accomplish particular goals. We are moving beyond the basics in Vermont, and it is important to utilize this important conservation tool in a way that benefits not only the watershed, but also your farm.

UPCOMING OPPORTUNITY FOR FARMERS TO DEVELOP GRAZING PLANS

By Cheryl Cesario, Grazing Outreach Professional

When farmers are considering grazing as a new management practice, or want to change or improve an existing system, there are many questions from both the animal perspective and the land perspective: Is this going to work? Will my animals like it? What will this look like? How will I do it?

These are all reasonable questions, which are not easily answered in a one or two-hour farm visit. I find the most successful grazing systems develop when there is farmer involvement in the planning process, and the farmer has a good relationship with a service provider and other farmers who can answer questions and share ideas.

This fall we will start offering a new grazing management course for farmers who want to learn about the benefits and challenges of grazing – from both economic and environmental perspectives. Each farmer will develop a plan specific to their operation which takes into account their
farm goals. The class will meet once per week over the course of a month, and each farmer will receive a copy of Sarah Flack’s book The Art and
Science of Grazing as the course textbook and helpful future reference. Outside of class, one-on-one farm visits will provide additional support
as new practices and strategies are implemented on the ground.

Here is a sampling of what the class will cover:
• Pasture plant identification of common species, looking at favorable growth conditions and how plants respond to grazing impact.

• Pasture nutrition – how it can affect grazing behavior, overall intake, and animal performance.

• Grazing management concepts such as measuring dry matter availability, determining paddock sizes, stocking rate versus stock
density and overall acreage requirements.

• Soil health in pasture systems and the benefits of soil, forage and manure testing to understand nutrient cycling and nutrient management within pasture systems.

• Pasture system design to determine infrastructure needs, and management techniques to avoid overgrazing damage, decreased
carrying capacity and other negative impacts.

• Grazing record keeping systems and the benefits of monitoring and documenting activities.

Eligible farmers will be able to use the grazing plan they develop in class to apply for USDA Natural Resources Conservation Service (NRCS) funding opportunities to help cost-share a variety of grazing practices. However, new infrastructure alone will not create improvements. Achieving healthy pasture ecosystems requires an understanding of the relationship between the soil, the plants and livestock grazing behavior. A clear goal and a plan based on plant and animal needs are essential for success. We anticipate the course will run from mid-October to mid-November, with up to 12 hours of classroom and planning time.

SPRING 2017 NEWSLETTER INTRODUCTION

FOCUS ON AGRICULTURE IN THE CHAMPLAIN VALLEY AND BEYOND

  By Jeff Carter, Agronomy Specialist,

Champlain Valley Crop, Soil & Pasture Team

Agronomy and Conservation Assistance Program

Nutrient Management Plan (NMP) classes have been a major emphasis of activity for the past months and 31 farmers completed their NMP through
the UVM Extension goCrop™ classes that were held in Richmond, Middlebury and Pawlet. Statewide, over 70 farmers completed the classes offered by the St. Albans and Middlebury Extension Crop teams so farmers can develop their own crop management plans. There are plenty of field meetings, corn planter clinics, farmer manure trainings, stream floodplain restriction discussions, and buffer workshops going on now and more to come this spring, all geared toward how farmers will adopt practices to meet the Required Agricultural Practices (RAP) rules. Stay updated about current events via e-mail: join our email list at
www.uvm.edu/extension/cvcrops.

Field Research/Demonstration

We will be starting some new projects this year with financial support from the NRCS Vermont Conservation Innovation Grant Program; the Agency of Agriculture, Food and Markets; and the Northeast SARE program to continue our work with local farmers. One study
will start a benchmark program for the economics of growing cover crops and using no-till for crop planting. What is the true cost and benefit of moving to no-till with cover, and then how profitable are you? We need better data about the Vermont farms who have changed to these new crop systems to be sure of the right investments for your particular farm. Starting with a handful of farms who have agreed to provide the details
about their operations, the data from this project will reflect current finances of these conservation practices as they are used here on our soils.

Whole-farm phosphorus (P) mass balance has been around for some time,
but few farms complete the accounting of where the extra P comes from. We have a project to work with several farmers and their feed consultants to collect data on the extent of P imported to local dairy farms. This is good information to have, but really the issue is what to do then? Not all P is leaving the farms, and that is why farmers use the P-Index to better understand the risk of P loss and “plug” any leaks in the farm system.
We will be field testing the new 2017 Vermont P-Index and a new Northeast P-Index on several farms and relate that data to whole-farm P-Mass balances and farm conservation. We will collect data to help farmers with crop management decisions under the revised Vermont P-Index. This will then be used to address the NMP 590 standard, which is the basis for all farm nutrient plans. What to do then if you have a high phosphorus soil test? Another study we have is to evaluate the use of field applications of amendments to reduce soil test P in the field. We will be looking at three types of gypsum, including one with humates, also contrasted with short-paper fiber (SPF). When spring does get here, we
will also see how good the cover crops perform that we planted last fall.

VERMONT RAP RULES
The Vermont Required Agricultural Practices rules affects all farmers this year, and so it affects our Extension work. Focus on Agriculture means a focus on helping you to learn (like Poop Skool) and then figure out the best next steps to take (whatever that is). Give us a call, or just come to the meetings that we host with the Champlain Valley Farmer Coalition.
This is a great way to keep up with new ideas so you can deal with changing times in Vermont agriculture.

RMA UPDATE: STREAMLINING PROGRAMS MEANS LESS EFFORT FOR FARMERS

Acreage Crop Reporting Streamlining Initiative (ACRSI)

By Jake Jacobs, University of Vermont Risk Management Education

Farmers are time-strapped folks. Having to report the same thing to multiple agencies can seem like a waste of time. Welcome, ACRSI.
ACRSI is a joint effort among producers, Farm Service Agency (FSA), Risk Management Agency (RMA), and the crop insurance industry. The Acreage Crop Reporting Streamlining Initiative (ACRSI) replaces duplicative crop reporting of common acreage information by producers to both the Farm Service Agency (FSA) and Risk Management Agency (RMA). Producers now have multiple ways in which to report their common acreage data and will not have to report the same information twice to both FSA and their crop insurance agents, saving time and potentially reducing inadvertent errors. ACRSI is available nationwide for the 2017 acreage reporting season.
Crops shared under ACRSI include alfalfa, barley, canola, corn, grass, oats, rye, sorghum, soybeans and wheat, as well as acres under the Conservation Reserve Program (CRP) and fallow fields. Other crops in this program: cotton, peanuts, rice and sunflowers. These cover approximately 94% of the cropland acres reported to FSA and RMA, and have similar reporting requirements with both agencies. FSA and RMA will gain experience collecting and sharing data for these crops, and will use the
lessons learned to make informed decisions whether to include additional
commodities in the future.

UPCOMING EVENTS AND INFORMATION FOR SUCCESS

Buffers and Grassed Waterways, Oh My!

We know, buffers and grassed waterways are not always the favorite
topics of farmers, but when it comes to water quality, they can
make a big difference. With our grant focus in the McKenzie Brook
we will be hosting spring and summer field events. Look for event
details soon, and please let us know if you would like to host one
on your farm. We will discuss: New RAP rule on buffers in effect April 15, 2017. All farmers covered under the RAPs will be required to have a 25-foot buffer on streams and a 10-foot buffer on ditches. Let’s face it, this will mean adjusting plowing and planting practices this spring.
Grassed waterways. Although not mandated, these can be very
effective, particularly where other practices aren’t enough to
prevent gully erosion.

Planter Clinics: Getting Ready to No-Till

For the third year, our team is hosting no-till corn planter clinics in coordination with Champlain Valley Farmer Coalition. Are you on our e-mail list to find out dates and details? Like conventional till, successful no-till comes down to healthy soil, a properly set-up planter, and the right timing: they’re even more critical since you can’t correct mistakes with an extra harrow pass!

No-Till Resources at
www.uvm.edu/extension/cvcrops
Including Factsheets, No-Till Corn Planter Tune Up Checklist, and Closing Wheel Guide

Upcoming No-Till Planter Clinic Event:
  • April 6, 2017 at Gosliga Farm in Addison, VT from 10 am to 12 pm, located on Sunset Lane (off Rte 17). For more information about this event, see our flyer or contact Rico Balzanzo at (802) 773-3340 ext. 281

WELCOME CLAIRE BOVE!

Claire Bove is the newest addition to the Middlebury UVM Extension office, hired in February as the Vermont Coordinator for the High School Equivalency Program (HEP).  HEP helps eligible migrant and seasonal farm workers and members of their immediate family obtain the equivalent of a high school diploma, and subsequently gain employment or pursue postsecondary education.

All participants receive a free tablet and access to online curriculum available in both English and Spanish, which enables program participants to complete an individualized and self-paced course of study in preparation for passing the GED exam.  This is a new program offered in partnership with the other New England states of Maine, Massachusetts and New Hampshire, and Claire will be working hard to build these partnerships and to recruit students across the state in hopes of graduating 20 Vermont individuals a year.

Claire isn’t totally new to UVM Extension or to the Vermont farmworker population, as she has been working with the Migrant Education and Bridges to Health Programs as a Recruiter and Health Promoter since last summer.  The Migrant Education Program provides free educational support services, English classes and life skills training to eligible children and youth who work or whose families work in seasonal or temporary agriculture.  Bridges to Health is a health outreach program that offers care coordination and supports health care access for migrant farmworkers in Vermont.  Claire has enjoyed the opportunity to provide farmworkers with valuable access to education and healthcare resources through her work with these UVM Extension programs, and she is excited to pursue this new opportunity with the High School Equivalency program and to continue serving the Vermont farmworker community.

Claire grew up in Brandon, VT and completed her undergraduate studies at UVM focusing on biology and Spanish. She has since lived in Austin, TX, Chicago, IL and multiple locations in Spain, and has spent time cooking professionally, studying to be a sommelier (wine steward), teaching English, and working in research.  She is now happily settled in Cornwall, VT with her husband and young son, where she enjoys being outdoors, gardening, cooking for friends and family, and fishing.
