Newsletter Highlight From Grassland Manure Injection: By The Numbers (pg. 4) With funding from VAAFM’s Clean Water Fund and the help of Ken and Debbie Hicks at Hicks Equipment, we purchased the right equipment from the Netherlands. With the expertise of Eric Severy of Matthew’s Trucking to operate it, we began demonstrating the utility of this system. Shallow slot grassland manure injection gets liquid dairy manure just two inches below the soil where it is protected from runoff during rain events while still well within the root zone where the plants will use it.

Save the Date: 2021 No-Till Cover Crop Symposium March 4-5, 2021. More information coming soon. We’re joining forces with the Northeast Cover Crop Council to bring you a full day and a half of information related to no-till and cover cropping. go.uvm.edu/ntccs If you missed this year’s symposium you can also read presentation pdfs and the proceedings online.
As of right now, the UVM Agricultural and Environmental Testing Lab is still receiving manure and soil samples directly and the lab in Maine that UVM works with us is still open. However, we will not be transporting samples from our office in Middlebury to the lab in Burlington. Additionally, please understand that the manager of the lab will not be in the office every day and there many be an additional delay in processing samples. Call the lab at 802-656-3030 if you have questions.
Manure Samples: It’s nearing time for manure spreading… and also manure sampling! The best time to sample manure to get an accurate sample is right when you are about to spread it.
We ask that you sample, freeze and hold on to manure sample(s) for a future date
to be analyzed when we can transport it to the lab. Manure can be sent
in the mail, but it’s more ideal to just hold on to it. If you need a
timely result, call the lab, you may be able to send it directly to
Manure can be frozen for months, just make sure you leave enough space in the jar for expansion.
manure jars will be left in the sample box at the entrance of our
office, but any plastic quart jar could work – do not use glass jars.
Our fact sheet on how to take a manure sample can be found here.
The form for manure sample analysis can be found here.
While we recommend soil sampling at the same time each year, given circumstances, if you can wait to sample it is advised to do so. If you do need an analysis, you can direct mail your soil sample(s).
There will be soil test kits left in the sample box at the entrance of our office, but any clean sandwich type plastic bag will work. You only need 1/2 to 1 cup of soil per sample – over doing it doesn’t help the lab and costs you money. Just make sure you take adequate sub-samples, mix your soil sample well, and send a representative mix. Soil probes will not be available until a future date.
The form and instructions for soil sample analysis can be found here.
If you have any questions about manure and soil sampling you can still give our office a call, and someone will get back to you – 802-388-4969.
Did you know you need to update your NMP every year to stay in compliance with the State of Vermont Required Agricultural Practices (RAPs)?
If your plan is out of date or you need assistance in updating your nutrient management plan, UVM Extension can help!!
If you took a NMP class through UVM and designed your plan in goCrop, please call the office where you took your original NMP class, or contact your closest location (listed below). You will need manure sample results every year, soil sample results every three years, and field records of the activities you performed annually. You may also need updated rotation calculations, depending on your situation. UVM Extension can help you identify everything you need and walk you through the process of getting it accomplished.

Thursday, August 31st 2017 Short Season Corn Hybrid Field Day11:00 AM – 2:00 PM
Vorsteveld Farm | 3925 Panton Road, Panton, VT (just across the street from the telephone building, next to the new solar panel installation)
Join the UVM Extension’s Champlain Valley Crop, Soil & Pasture Team and local seed suppliers in the field to see our corn hybrid demonstration, comparing shorter season corn varieties (85-98 day). Can we accomplish high yielding corn and timely cover crop seeding? Come check it out. We’ll take a trip down the road and check out some long season hybrids too! Research in northern VT has suggested that variety, as opposed to just day length, is important in determining corn yield. To this end, we have planted 21 corn hybrids ranging from 85 DRM to 98 DRM to assess yield and quality. The objective is to test varieties on our soils and find optimum day length so that there is more time in the fall for cover crop seeding and establishment without sacrificing yield. We will also have the opportunity after lunch to look at some longer day hybrids in a different field and take a look at this farms novel approach to no-till, manure application and cover cropping.
We just finished a two-year, multi-farm study on the health of clay soils, funded through a VT Conservation Innovation Grant through the NRCS. Measures of soil health (using Cornell’s soil health test) were not consistent, and we found that comparing practices over time was more informative than comparing field to field. One interesting, and maybe
obvious, lesson was the correlation between soil health practices and crop yields.
So, how do soil health practices influence yield? Research suggests soil health can improve yields. It is important to note our project focused on demonstration, not replicated research. We compared no-till and conventional/reduced till corn silage on 5 farms with clay fields in our region. A simple t-test revealed no significant difference in yield between no-till (19.1 tons/acre) and conventional (19.2 tons/acre). More importantly, we were able to demonstrate that a farmer can grow no-till without yield losses, and be successful with good management practices. A yield gain might take time as the soil builds up its condition.
We also wondered how cover crop species or mixes might affect corn silage yield. We had an opportunity to use a field where the corn was accidentally killed. We planted 15 different combinations, including 4 single species, 6 two-way mixes, and 5 three-way mixes. This project was a slight anomaly in that the cover crops were planted with a drill in late August, which allowed for a more vigorous production of all cover crops. Radish was a star in the fall, maximizing both phosphorus and nitrogen uptake. We did not measure phosphorus content in the spring, so we do not know how much was retained in the soil. It seems to have allowed
for more available nitrogen in the soil at the time of a pre-sidedress nitrogen test (PSNT), therefore requiring less nitrogen. Surprisingly, legume mix covers had good fall biomass, but that did not translate into more N mineralization.
We applied nitrogen to each plot as per the PSNT recommendation for 20 tons/acre corn silage. At the end of the season, we measured corn silage
yield and compared that to nitrogen applied (see graph). The winter rye plot had a lower corn silage yield and required more nitrogen. Other than the nutrient effect of less uptake and slower decomposition, there may have been a physical barrier created by the standing rye crop, which was particularly vigorous in the spring. However, our three-way mix (winter rye – oats – radish) actually had the highest average corn silage yield, even though it required more N at PSNT time than the pure radish stand.
So, do not go abandoning your winter rye just yet. In fact, we think this three-way mix has promise and we are looking for a mix that gives both fall and spring soil conservation. Radish alone will winter kill, which may be good for mineralization, but not as good for spring soil conservation. Oats also winter kill but provide faster fall soil cover than rye by itself.
When using an over-wintering cover crop, it is clear that timing and success of termination is critical for subsequent crop yields. Nitrogen mineralization may happen later in the season with a plant such as winter rye that has a heavier carbon content. In a no-till system particularly, you may need to adjust your nitrogen rates/timing and put more on upfront. If you are using cover crops, a PSNT seems like a wise investment.
It is also important to remember that soil health is a long game, and it may take time to see the results of your labors with cover crops. We have replicated this project by replanting these cover crops in the fall of 2016, this time planted in September, and will look at this again this coming season.
