Spring Forage Establishment

Kyle Verhoff, Allen Gahler, Jason Hartschuh, CCA, OSU Extension

Planting window runs to late April for southern Ohio and to early May in Northern Ohio.

As soil temperatures rise and the chances of a morning frost decline, the window to spring-establish forages is open. In the spring, the combination of weather and plenty to do make planting opportunities scarce. To take advantage of those short planting windows, the following are items to consider to improve chances for a successful forage establishment this spring.

  1. Soil Fertility and pH: Set up your forages with the best starting conditions you can by providing sufficient available nutrients and a soil pH that allows for those nutrients to be taken up. Follow the Tri-state Soil Fertility Recommendations (https://forages.osu.edu/forage-management/soil-fertility-forages). Phosphorus levels for grass are optimal in the . . .

Forage Weeds: Fall Forgotten and Spring Startups

Spring means rapid forage growth, but it also means rapid weed growth. Due to the variability of spring weather, there are often only a few opportunities to control emerging summer annual weeds, winter annuals missed in the fall, and biennials that are small enough to effectively control. To manage weeds before they become a problem in forages, it is important to scout and plan accordingly. Forage is a broad category, and the spring weed control plan can look very different between species and operations. The problem weeds and whether control is necessary are going to be different between permanent pasture systems and alfalfa fields, and highly dependent on the consequences of specific weeds.

In established alfalfa, the decision for weed control of some winter annuals like henbit and field pennycress will depend on the severity of the weed presence, the age of the stand, and the end purpose of the forage. If the weed pressure is high, the stand is young, or the lower forage quality of the weeds interferes with the goal of producing dairy-quality hay, the weed control treatment may be worth the associated cost. In a grazing system, it may be more pertinent to control weeds in the spring to ensure weeds that aren’t grazed don’t go to seed. Numerous weeds can be a problem in forage systems. Reference the 2024 Weed Control Guide for specific recommendations following this general overview.

Summer annuals are most effectively controlled when they are small in the spring. An example weed is common cocklebur, a summer annual that is competitive in forage stands. The seeds of common cocklebur are toxic to livestock and maintain toxicity when cut as part of hay.

In established pastures, there are many effective control options for summer annual broadleaf control, including:

  • 2,4-D
  • Crossbow
  • PastureGard
  • GrazonNext

Winter annual weeds are most effectively controlled in the fall when they are small and have not lived through the winter, but there is a window in the spring to control anything missed. A winter annual that is always a concern come spring is cressleaf groundsel, due to its toxicity to livestock. Cressleaf groundsel should be actively managed; if an infestation builds up to where mature weeds with yellow flowers are visible, herbicide control is no longer an option, and the weed maintains its toxicity even after cut. The first cutting of an area heavily infested with common groundsel will likely have to be discarded instead of sold or fed. There are limited herbicide options for control; in pastures and grass hay fields 2,4-D is an effective choice, but will kill any desired legumes present. Weeds can commonly be seen as pretty flowers by neighbors and left to bloom, be sure to scout property edges to lower the risk of a weed infestation jumping into the field the following spring.

In alfalfa and legume hay, some of the chemical control options include:

  • 2,4-DB (Butyrac)
  • Pursuit
  • Raptor
  • Glyphosate (Roundup Ready alfalfa or spot treatment only)

Another group of weeds that we have a chance to control in the spring are biennials. Poison hemlock is a biennial that commonly finds its way into forages, moving in from field edges and fence rows. Poison hemlock is toxic when ingested by livestock and can also cause skin irritation. Poison hemlock is most often a problem in pasture systems that are overgrazed and where there is inadequate grass growth. Where other grazing options are available, animals tend to avoid this plant, but control of poison hemlock should still be a priority. Being biennial, it is most effective to control poison hemlock while it is in the rosette stage.

For the control of poison hemlock in pasture systems, herbicide options include:

  • Remedy Ultra
  • Crossbow
  • Dicamba

Poison Hemlock

All the previous examples given were broadleaf weeds, but there is also the opportunity to control grass weeds in alfalfa and legume fields in early spring. Roundup Ready alfalfa makes glyphosate and products such as Extreme an option. In conventional alfalfa fields, products containing clethodim (Arrow, Select Max, etc.) and Poast are effective at controlling grass weeds.  Weed control in forages is highly situational; it is important to read the herbicide label to ensure effective weed control, limit potential damage to desired forages, and to be aware of any potential grazing or harvest restrictions.

The Ag Law Harvest

By:Jeffrey K. Lewis, Esq., Program Coordinator, OSU Income Tax Schools & ANR Extension Thursday, March 28th, 2024
Picture of utility vehicle.

Spring has officially sprung, and so have a few interesting legal updates. In this edition of the Ag Law Harvest we cover aggravated vehicular assault in a farm utility vehicle, “Made in the USA” labels, the Corporate Transparency Act’s legal woes, USDA’s Dairy Margin Program, and the U.S House Committee on Agriculture’s Agricultural Labor Working Group’s final report.

Driver of Farm Utility Vehicle Cannot be Found Guilty of Aggravated Vehicular Assault. 
The Supreme Court of Ohio ruled that a driver of a farm utility vehicle involved in a crash cannot be convicted of a felony for injuring passengers because the vehicle does not meet the definition of a “motor vehicle” under Ohio’s criminal code. Joshua Fork of Sandusky County crashed his Polaris utility vehicle while driving under the influence at a party in 2020. Two of Fork’s passengers sustained serious injuries as a result of the accident. Fork was convicted of operating a vehicle under the influence (OVI), and two counts of aggravated vehicular assault. Fork did not contest his OVI conviction but did appeal his aggravated vehicular assault conviction to the Sixth District Court of Appeals. The case eventually made its way to the Supreme Court of Ohio.

In its decision, the Court found that Ohio law has two definitions of “motor vehicle.” One definition applies strictly to traffic laws and the other applies more broadly to Ohio’s “penal laws.” The Court held that the definition of “motor vehicle” that applies to penal laws, such as aggravated vehicular assault, exempts utility vehicles. The Court concluded that because of the utility vehicle exemption and the fact that the utility vehicle’s principal purpose is for farm activities, Fork cannot be found guilty of vehicular aggravated assault.

USDA Announces Final Rule on “Made in the USA” Labels. 
The U.S. Department of Agriculture (“USDA”) announced the finalization of a rule to align the voluntary “Product of USA” label claim with consumer understanding of what the claim means. The USDA’s final “Product of USA” rule permits the voluntary use of the “Product of USA” or “Made in the USA” label claim on meat, poultry, and egg products. However, these labels can only be used if the products are derived from animals that were born, raised, slaughtered, and processed in the United States. The rule aims to prevent misleading U.S. origin labeling, ensuring that consumers receive truthful information about the origins of their food.

Under the final rule, the “Product of USA” or “Made in the USA” label claim will remain voluntary for meat, poultry, and egg products. It will also be eligible for generic label approval, meaning it won’t require pre-approval by the USDA’s Food Safety and Inspection Service (“FSIS”) before use, but establishments must maintain documentation supporting the claim. Additionally, the rule permits other voluntary U.S. origin claims on these products, provided they include a description on the package of the preparation and processing steps that occurred in the United States upon which the claim is made.

Corporate Transparency Act Loses First Federal Court Battle. 
As we have previously reported (here), the Corporate Transparency Act (“CTA”) requires certain business entities to file Beneficial Ownership Information (“BOI”) with the Financial Crimes Enforcement Network (“FinCEN”) or face civil and criminal penalties. However, an interesting twist in the CTA saga has occurred. A federal court in Alabama issued an opinion ruling the CTA unconstitutional, concluding that the CTA exceeds the U.S. Constitution’s limits on Congress’s power, and issued an injunction against the U.S. Government from enforcing the CTA against the named plaintiffs in the case.  Therefore, the named plaintiff, Isaac Winkles, and companies for which he is a beneficial owner or applicant, the National Small Business Association, and the approximately 65,000 members of the National Small Business Association are currently not required to report beneficial ownership information to FinCEN. Everyone else must still comply with the CTA and the BOI reporting requirements.

FinCEN released a statement acknowledging the court’s ruling but emphasized that only the named plaintiffs are excused from reporting beneficial ownership information to FinCEN at this time. On March 11, 2024, the U.S. Government filed a notice of appeal of the lower court’s ruling, hoping to reverse the injunction and the court’s decision. We will continue to monitor the situation and keep you informed of any updates to the CTA and BOI reporting requirements.

USDA Announces 2024 Dairy Margin Coverage Program. 
The U.S. Department of Agriculture (“USDA”) announced that starting February 28, 2024, dairy producers in the United States can enroll in the 2024 Dairy Margin Coverage (“DMC”) program. Enrollment for the 2024 DMC coverage ends on April 29, 2024.

The USDA’s Farm Service Agency (FSA) has made revisions to the DMC regulations to allow eligible dairy operations to make a one-time adjustment to their established production history. This adjustment involves combining previously established supplemental production history with DMC production history for dairy operations that participated in Supplemental Dairy Margin Coverage in previous coverage years. DMC has also been authorized through the calendar year 2024 as per the 2018 Farm Bill extension passed by Congress.

FSA Administrator Zach Ducheneaux encourages producers to enroll in the 2024 DMC program, citing its importance as a risk management tool. The program has proven effective, with over $1.2 billion in Dairy Margin Coverage payments issued to producers in 2023. Ducheneaux highlights the program’s affordability, noting that it offers a sense of security and peace of mind to producers.

DMC is a voluntary risk management program that provides protection to dairy producers when the margin between the all-milk price and the average feed price falls below a certain dollar amount selected by the producer. In 2023, DMC payments were triggered in 11 months, including two months where the margin fell below the catastrophic level of $4.00 per hundredweight, marking a significant development for the program.

House Committee Releases Final Report Recommending Changes to H-2A Program. 
On March 7, 2024, the U.S. House Committee on Agriculture’s Agricultural Labor Working Group (“ALWG”) released its final report containing policy recommendations for U.S. agricultural labor. The report includes significant reforms to the H-2A program, many of which, as announced by the ALWG, received unanimous support from the bipartisan working group. The recommended policies encompass creating a single H-2A applicant portal, implementing H-2A wage reforms, establishing a federal heat standard for H-2A workers, and granting year-round industries such as livestock, poultry, dairy, peanuts, sugar beets, sugarcane, and forestry access to the H-2A program.

Proactive Forage Management for Grazing Success

– Jennifer J. Tucker, Ph.D., Associate Professor and Beef Extension Specialist, University of Georgia

The goal of grazing management is efficient production and utilization of a forage base.

Attend any forage focused Extension program and you will assuredly discuss the importance of soil fertility, forage quality, having a forage plan, and utilizing proper seeding and planting practices. Each of these are key fundamentals to efficient and effective forage management and utilization and should not be overlooked in this article. A limitation of even one of these areas can have a dramatic effect on overall forage production and operational productivity. Today, however, we are going to take a closer look at what’s happening between the pasture and the highway and discuss a few other key variables in forage management.

The Goal of Grazing Management
Whether a large producer with generations of experience, or a smaller operation just starting out, the overall goal of forage grazing management is the same: Efficient production and utilization of a forage base that is able to meet the needs of the livestock herd.

Below are three key principles needed to . . .

How to Use a Grazing Stick

Christine Gelley, Extension Educator, Agriculture and Natural Resources, Noble County, Ohio State University Extension

A grazing stick helps estimate days of grazing that remain in a paddock.

Measuring the amount of forage available for livestock to graze is a helpful task for designing and adjusting pasture rotations for grazing livestock. There are many potential methods for measuring the amount of forage mass that is growing in a pasture. All of them require time spent in the pasture and repetitious measurements to develop estimations of whole pasture forage availability. One of the simplest methods for estimating forage availability is using a grazing stick.

What does the grazing stick do?

A grazing stick combines information about forage height, forage density, species of forages growing in the pasture, and residual grazing heights into a tool that . . .

Minnesota Goat Confirmed to have Highly Pathogenic Avian Influenza (HPAI)

North Dakota State University and University of Minnesota Extension Teams
(Previously published online with North Dakota State University Extension and Ag Research News: March, 21, 2024)

A juvenile goat in Minnesota recently tested positive for highly pathogenic avian influenza (HPAI). While HPAI has been detected in predatory mammals that prey on infected birds, this is the first identified case of HPAI in domestic livestock in the U.S. The goat lived on the same premises where a poultry flock tested positive for HPAI in late February. The goat shared the same pasture and sole water source as the poultry flock.

HPAI is a known disease of wild and domestic poultry and waterfowl. There is limited information available about HPAI infection in ruminants, though in some species, animals with immature or compromised immune systems appear to be at greater risk of infection. Only young goats were afflicted in the Minnesota case, not mature goats. This case is being investigated by the Minnesota Board of Animal Health with the assistance of the U.S. Department of Agriculture.

“As we aim to protect livestock for our North Dakota producers, the risk of transmission increases during spring,” says Miranda Meehan, North Dakota State University Extension livestock environmental stewardship specialist.

“While we don’t envision this zoonotic transmission to be commonplace, good biosecurity protocols separating livestock from poultry/waterfowl is a good production practice to reduce the potential spread of HPAI to our small ruminants during the spring migration of wild birds,” says Travis Hoffman, NDSU Extension sheep specialist.

“H5N1 HPAI has been detected in wild birds throughout all U.S. migratory flyways, says Dr. Gerald Stokka, NDSU Extension veterinarian and livestock stewardship specialist. “Wild birds can be infected without showing symptoms of the infection. While waterfowl are the primary carriers, positive cases are being documented in predatory birds and mammals, and now domestic goats.”

NDSU Extension experts support the biosecurity practices released by University of Minnesota Extension that can reduce the potential for domestic animals to contract HPAI. Recommended practices include:

  • Do not allow poultry and livestock species access to ponds, wetlands and other stagnant water sources that are frequented by wild waterfowl such as ducks, geese or swans.
  • Watch poultry and livestock for signs of illness, including reduced appetite, fever, inability to stand, depression, nasal discharge, diarrhea, coughing and change in behavior.
  • Consider housing poultry separately from other livestock species and minimize poultry access to pasture areas that are grazed by other livestock species.
  • Do not allow poultry, waterfowl and wildlife to share water sources and feedstuffs with other livestock species.

Protocols for protecting livestock include:

  • In the Minnesota goat case, infected goats shared the same water source as infected poultry. Limiting livestock exposure to potentially inflicted-HPAI poultry is the first action of defense.
  • Current influenza vaccines used in horses are not effective against HPAI. Always consult your veterinarian before administering vaccinations.
  • Many cattle are vaccinated against Parainfluenza-3 (PI-3), a virus that can cause respiratory issues. Parainfluenza viruses are in a different family from influenza viruses and the PI-3 vaccine does not provide protection against influenza.
  • If you have an unexplained death in one of your animals, consult with your farm veterinarian, contact the North Dakota Board of Animal Health.

“There is no evidence that anyone has contracted the virus from eating a fully cooked bird, either domestic or wild,” says Julie Garden-Robinson, NDSU Extension food and nutrition specialist and professor of health, nutrition and exercise sciences. “It is always a safe practice to fully cook wild game to 165 degrees Fahrenheit, regardless of whether there is a threat of HPAI.”

Avian influenza surveillance and testing in wild birds is being done by the USDA’s Animal and Plant Health Inspection Service (APHIS) and the North Dakota Department of Game and Fish.
