Addressing Fertility, Forage and Grain Production with Farmer Ingenuity

Monday, July 19, 2010, 11:00-3:00 pm, The Beidler Family Farm, Randolph Ctr, VT
Unwilling to rest on past successes,Brent and Regina Beidler continually seek innovative ways to address common farming challenges such as limited growing seasons, production of a single commodity, nutrient management and pasture compaction. This field day will highlight some of the farm activities to manage these challenges, including grazing season extension through the use of Japanese millet and brassicas, pasture compost application, growing small grains such as spelt and oats for sale and bedding, and use of a Keyline plow. We’ll also have demonstrations of spelt hulling and a newly-completed solar tractor. After lunch, the group will visit several experiments hosted at VTC including UVM organic corn and pasture species trials, and a UVM graduate student experiment undersowing spring wheat with red clover to address Fusarium head blight.
COST: $10 to attend. Lunch provided by the NOFA pizzamobile. Please register by July 9.
DIRECTIONS: The Beidler Family Farm is located off I-89 Exit 4, travel east 1/2 mile toward

Armyworms Reported in Maine

Dr. Heather Darby, UVM Extension

Download a PDF version of this article.

Armyworm damage has been reported in Maine. Please don’t panic, but do go out and scout your corn and grass fields for armyworms. When full grown, the caterpillars can be almost 1.5 inches long. The caterpillars are usually greenish or brownish, but can be almost black. The sides and back of the caterpillar have light colored stripes running along the body. The caterpillars normally feed at night and much damage can occur before they mature. The preferred foods are grasses including corn, grains, and timothy. They will feed on other plants if grasses are unavailable. Feeding will start on the lower leaves and move upwards. A large population can strip an entire field in just a few days. When the field is eaten they “march’ to adjacent fields. Corn fields that are minimum or no-tilled into grass sod or fields infested with grass weeds are most susceptible. For more information on scouting and control options please contact Dr. Heather Darby at the University of Vermont Extension at (802) 524-6501.

Slug Populations are on the Rise

Continuous wet weather over the past 3 years presumably has led to a rise in slug populations. Slugs are a problem associated with fields with high amounts of crop residues. They like moist and cool conditions and primarily feed on crops after dusk and through the night. It is rare to see slug damage on hay and corn crops but over the last 2 years we have heard of several cases where field crops have been annihilated. You may not notice the slugs in the field during the day it is “the undercover crop pest”. They hide under residue and soil clods during the day and wait for the coolness of the night and crawl out to eat your crops. They leave a trail of slimy silvery white goo on the plants and the soil. The most typical species causing devastation to field crops is the grey garden slug (Deroceras reticulatum). Other less common species include the dusky slug (Arion subfuscus) and the marsh slug (Deroceras leavae). These slugs are common sights in corn and soybean fields, but not known to cause economic damage to field crops. Their damage looks as is hail has shredded the corn plants and eventually if the populations are high enough they eat entire plants. Generally fields that have high residue such as no-till and heavy weed populations are more likely to become inundated with slugs. Some plants can withstand 10 or more slugs per plant but others are more susceptible. Higher populations may warrant control or you can pray that it dries out. Certain management practices like tillage on a regular basis may help to reduce slug populations. Another management consideration is to alter planting dates prior to when slugs begin their heavy feeding or delay planting to when the soil has warmed and the slug populations have decreased.
Control of slugs with a pesticide is often difficult due to the slug’s ability to shed slime, simultaneously shedding the toxins.

Corn is Ready to Topdress

Dr. Heather Darby, UVM Extension

The corn crop is off to a good start this season. Many fields are at the stage of rapid nutrient uptake. A key decision that needs to be made by farmers is whether additional nitrogen should be applied to meet the crop’s need for the remainder of the season. The PSNT is one of the best tools available to gauge if supplemental nitrogen is needed. This test offers a diagnostic method for evaluating the nitrogen supplying capacity of the soil just prior to the plants period of greatest N demand. Corn plants begin their greatest uptake of N around the 5th leaf stage, or when the plants are approximately 12 inches tall at the center of the whorl. In contrast to traditional soil tests, the soil sample is collected from the top 12 inches of soil when corn plants are approximately 12 inches tall or at least one week before planned sidedressing. Growers who apply animal or green manures to their fields are especially likely to benefit from the PSNT. The organic matter in manure contributes nitrogen that is not well accounted for by other soil test methods. For assistance in collecting samples for PSNT testing contact your local extension specialist. Although the PSNT is one of the best tools we have to measure available nitrate it is not without short falls. The reliability of results from this testing procedure is heavily dependent on making sure the samples are collected, handled, and processed correctly. Even if sampling, handling, and processing are done correctly, the reliability of this test when values are low is sometimes questionable. If the values are high–greater than 25 ppm–then the odds are good that no additional N will be needed for the crop.

Vermont Oilseed Crop Production Cost and Profit Calculator

As Part of the Vermont Sustainable Jobs Fund’s ongoing Vermont Biofuels Initiative and UVM Extension’s research, a tool was developed intending to help farmers determine their total cost of production for oilseeds and oilseed products (e.g. meal, oil, biodiesel.)  The tool also allows the user to determine a potential profit based on assumed market pricing for these products.  Summary results are provided as reference and are based on either compiled Vermont oilseed grower data or other published data from other parts of the USA.  Whenever possible, the user should carefully review their own specific data to arrive at the entered information.  Click here for more information and to download a copy of the excel workbook.

Tamerlane Farm is a diverse dairy, livestock, vegetable and grass-fed beef operation in Lyndonville, VT.  Milk is produced for Organic Valley/CROPP Cooperative and they supply beef and vegetables to their family-ownedrestaurant, Northeastern Vermont Regional Hospital, St. Johnsbury School and Lyndon Institute. They also run a small composting operation where 5 tons of food waste per week from area schools, stores and restaurants is diverted from landfills, mixed with wood chips and manure and is converted to screened compost.  They worked with NRCS to develop a Comprehensive Nutrient Management Plan for the 420 acres they farm, and have been certified organic since 2003.
The Paris’ feed their cows a low-grain diet combined with high quality forages. They practice the hay in a day system and grow high energy grains as a complement to the high-protein pasture. We will tour their double cropping system of barley and turnips for late season grazing, the pastured poultry system as well as their vegetable gardens.

Emergence Problems Plague Vermont Corn Fields

Emergence Problems Plague Vermont Corn Fields

It was a great spring for planting. The conditions were dry and many folks were able to get their corn planted by mid-May. However, dry and cool conditions during planting have resulted in a number of corn fields with less than optimum germination. These stand losses could translate into yield loss at harvest time.
I have been asked by many, what is the penalty for uneven emergence?  Uneven stands will lower yields compared to stands where all the plants look the same. The later emerged corn is at a competitive disadvantage because it must compete with larger plants for moisture, sunlight, and nutrients. The amount of loss from uneven stands or reduced stands is difficult to estimate.  Studies from the Midwest indicate a 6% grain yield loss if a quarter of the plants emerge 1 week later.  A 17% yield loss can be expected if plants emerge 2 weeks later.  If the stands were filled in at this time the yield difference will only be 7%.  A 3 week emergence delay will decrease yields greater than 20%.  In some cases the corn will not emerge at all and yield losses will be higher than from uneven emergence. In fields with losses of ¼, ½, and ¾ of the stand, grain yields will be reduced by 10, 30, and 50% respectively. There have been no studies conducted to measure potential silage loss in uneven or reduced stands.
There are many factors that influenced corn seed germination this spring. Corn needs uniform soil moisture and temperature for rapid, uniform germination and emergence. The most likely culprits of uneven emergence and stand loss were the dry and cool soil! If the soil is too dry at planting, seedlings will emerge at different times.  The emergence times can vary between sections of the field, within rows of the field, and from one plant to the next. The primary factors that influence soil moisture in a field are differences in soil type or topography.  However, I think this year the biggest cause of moisture variation was from secondary tillage passes.  Secondary tillage will impact soil moisture because it will unevenly distribute moist and dry soil particles.  The more tillage trips before planting the more the soil would have dried out.  Many farmers plant corn at a 2 inch depth to ensure seed has adequate moisture to germinate. This year this depth may have been too dry as well. Crops that were seeded shallow would have been a greater risk for poor emergence.
Uneven soil temperature may also contribute to reduced or uneven emergence.  Corn will germinate and emerge slowly and unevenly when soil temperatures are less than 50F. Uneven soil temperatures in the seed zone can also be caused by variable soil type, drainage, seed depth control, and surface residue cover in reduced tillage systems. This year many farmers tried no-till and/or zone-till systems to reduce fuel costs. Uneven residue coverage in these systems causes lower soil temperatures under heavier cover than under barer spots in the field.  It is possible we also experienced uneven seeding depths due to the well worked soil.
Although it maybe too late to replant or fill in the stand, we will hope for an excellent growing season that will bring the existing corn stands to maximum yield potential.
