Featured Forage Publication: Crabgrass (AGR-232)

Crabgrass possesses significant potential for supplying high quality summer forage although it is considered a weed by many. A primary advantage of crabgrass is that it is well adapted to Kentucky and occurs naturally in most summer pastures, especially those that have been overgrazed. It is also highly palatable and a prolific re-seeder. Planting an improved variety of crabgrass is recommended because the production of naturally-occurring ecotypes varies greatly. Crabgrass is best utilized by grazing. Remember that the advantage of crabgrass as a natural reseeding annual can also be a disadvantage. Don’t plant crabgrass anywhere that you may not want it in the future. It can be a weed! Read the full publication here.

Quote of the Month: Good Variety Decisions Don’t Guarantee Success, But Bad Ones Can Guarantee Failure

book2Plant breeding is a relatively young science, but it has resulted in amazing increases in productivity. In the case of forage crops, many traits have been improved including forage yield, forage quality, disease resistance, insect resistance, timing of forage growth and tolerance to adverse weather conditions. Obtaining and using such information can greatly increase the likelihood of success in both establishment and production.

UK to host Novel Tall Fescue Renovation Workshop, March 19

DSC_0094Tall fescue is a double-edged sword for many livestock producers. University of Kentucky forage extension specialists are teaming up with the Alliance for Grassland Renewal to host a workshop to teach producers how to renovate their tall fescue pastures with a novel endophyte variety.

The Novel Tall Fescue Renovation Workshop will take place March 19 at UK’s Veterinary Diagnostic Laboratory located at 1408 Bull Lea Road in Lexington. The daylong event begins at 8:15 a.m. EDT.

Producers have widely used tall fescue in pastures for decades, because it survives well under many conditions including drought, cold, overgrazing, insects and diseases. However, the most common variety, KY-31, also contains toxins that can severely affect cattle and horse performance. By replacing it with a novel endophyte variety, producers can keep the beneficial aspects of the grass while reducing the negative impacts.

“There are a growing number of novel or friendly endophyte tall fescue varieties on the market, including UK’s own variety Lacefield MaxQ II,” said Ray Smith, forage extension specialist in the UK College of Agriculture, Food and Environment. “This workshop will help producers learn how they can begin to incorporate these new varieties into their operation. The workshop will also show producers how they can better manage existing KY-31 stands so they are safer for their animals.”

During the workshop, participants will hear from Kentucky producers, UK specialists and speakers from across the country. They will discuss fescue toxicosis and the economics, testing, establishment, management, products and incentives for renovating pastures with a novel variety.

Register here before March 11 for just $65 per person, and $80 after that date. Individuals can also mail registration forms to Krista Lea, University of Kentucky, N-222C Ag. Science Center North, Lexington, KY, 40546. Find more information here. ~ Katie Pratt

Addition: This event is certified for RACE CE (Veterinarian and Vet Tech), Certified Crop Advisor CEUs, and Extension agent in service training credits.

Forage Timely Tips: March

  • Continue pasture renovation by no-tilling seeding legumes.
  • Place small seed at 1/4 to 1/2 inch deep and check depth several times during planting; slow down for more precise seeding.
  • Continue feeding hay until adequate forage exists in the pasture for grazing.
  • Spring seeding of grasses should be done in early to mid-March (but fall is preferred)
  • Begin smoothing and re-seeding hay feeding and heavy traffic areas.
  • Graze pastures overseeded with clover to reduce competition from existing grasses. <Pull off before grazing new clover plants.>
  • Provide free choice high-magnesium mineral to prevent grass tetany on lush spring growth.
  • Apply 30-40 lbs N/acre (65-90 lbs urea/acre) for quicker spring greenup

 

Winter Damage Mitigation

Last year’s winter brought on a lot of winterkill and decimated the potential for forage production. Spring and summer did not provide many opportunities to establish new forage production fields. As a result, forage inventories are low and many forage fields are in poor shape, expected to yield well below their potential. What can be done? The fastest remedy is to improve what you have. While starting over will set you back until early summer at best, improving an existing field with a short term grass species provides more and earlier forage and is cheaper to accomplish. There are quite a few options for spring planting, each with their own “specialty”:Picture13

Frost seeding is a cheap and efficient way to overseed existing forage fields, but the window for frost seeding is closing fast. Seed is applied with minimal damage to the field, ready to germinate as soon as the conditions are suitable. Seed can be applied with a fertilizer spreader, but depending on equipment it may be challenging to get the seed evenly spread, as grass seed is very light. Make narrow passes when broadcasting in this manner. Using a drill to get the seed in the ground, will improve the establishment rate of non-coated seed. It offers an even seed placement and better seed-soil contact. ~ excerpt from DLF Pickseed Spring 2020 Forage newsletter.

Virginia Tech Testing Bee-Friendly Forage Material

webimage-89015880-EF69-4E71-94481EB88CA184C1Named for its predominant grass, the “fescue belt” stretches for 1,000 miles across the southeastern U.S., from Virginia and the Carolinas in the east, to Kansas and Oklahoma in the west. Tall fescue feeds cattle on thousands of farms and ranches in this stretch, according but cattle and wildlife can suffer from tall fescue toxicity.

A new study conducted at Virginia Tech aims to address problems associated with the predominance of toxic tall fescue on many southeastern farms. Led by Dr. Megan O’Rourke, the research team will plant native prairie grasses and wildflowers at research stations in Virginia and Tennessee and at six on-farm sites in Northern Virginia.

“We’re trying to transform the landscape to support both cattle and pollinators by planting more native wildflowers on farmland,” according to O’Rourke.

The $1.8 million project is funded half by a federal grant and half by contributions of time, land, cattle and money by Virginia Tech, the University of Tennessee, farmers working with the researchers, and a nonprofit called Virginia Working Landscapes. The team will test 20 different wildflowers native to Virginia and Tennessee and will measure which ones attract the most bees and, when planted alongside native grasses, produce the healthiest cattle.

Another faculty member working on the study is Dr. Ben Tracy, a Virginia Tech professor of grassland ecology who has been studying native prairie grasses and the effects of tall fescue on cattle for the past 15 years or so, the release says.

“The main health problem that fescue causes for cattle, fescue toxicosis, is not fatal, but it costs the cattle industry millions of dollars a year,” Tracy says. Affected cattle have trouble regulating their body temperatures in hot weather and they don’t eat as much and gain as much weight as healthy cattle. “Hopefully, adding native grasses and wildflowers to pastures will reduce fescue toxicosis.”

If this study succeeds, adding native wildflowers to pastures in the fescue belt will become a new conservation practice that USDA’s National Resource Conservation Service will cost share. ~ Katie James, Bovine Vet Online
