RR Alfalfa Case Reaches High Court
The U.S. Supreme Court heard oral arguments this morning, April 27, on Monsanto’s challenge to a three-year ban on genetically engineered alfalfa. We’ll be reporting on a post-argument panel discussion hosted by the Environmental Law Institute at hayandforage.com. Feel free to express your thoughts at the end of that story or find us on www.facebook.com/hayandforage. Or tweet us: @hayandforage.

At issue is a 2007 lower-court ruling that stopped the sale and planting of Roundup Ready alfalfa seeds until USDA’s Animal and Plant Health Inspection Service (APHIS) completed an environmental impact statement (EIS) on the potential environmental effects of deregulating the product. Monsanto appealed that decision in 2008 and 2009, but lost both appeals. The Supreme Court agreed to take the case this past January. This will be the first genetically engineered crop case ever heard by the court. See a “Timeline Of Key Roundup Ready Alfalfa Events” developed by Monsanto.

In a final reply brief filed with the court in mid-April, Monsanto attorneys said the case is about fairness and choice for farmers. Among the company’s major contentions:

  • The safety and efficacy of Roundup Ready alfalfa was never an issue in the original lawsuit against USDA; however, the injunction took away farmers’ rights to choose to plant the technology – without scientific reasoning.
  • Farmers should be able to count on biotech crop approvals issued by the experts in federal agencies – or at least be confident that challenges to these decisions require consideration of scientific evidence.
  • Having a sound process for resolving disputed facts, like those in this case, serves the interests of farmers and the public. Courts should not substitute facts reviewed by expert agencies, in this case APHIS-USDA, with their judgment.
A total of 18 agricultural, business and legal groups have filed five friends-of-the-court briefs in support of Monsanto. Included are the American Farm Bureau Federation, National Alfalfa & Forage Alliance, the U.S. American Petroleum Institute, National Association of Home Builders, Allied Education Foundation and the Pacific Legal Foundation. See the briefs and get other information on the case.

In a posting on its Web site last week, the Center For Food Safety (CFS) noted that the state attorneys general in California, Massachusetts and Oregon have filed a brief supporting the center’s opposition to Monsanto in the case. The brief emphasizes the “states’ interests in protecting their natural resources and their citizens’ rights to be informed about the environmental impacts of federal actions.” CFS brought the original lawsuit that led to the 2007 Roundup Ready alfalfa ban.

Other groups filing briefs supporting the CFS position, according to the posting, include the Union of Concerned Scientists, the National Resources Defense Council, Defenders of Wildlife, the Humane Society of the U.S., the Center for Biological Diversity, organic businesses, farmers and more than a dozen law professors, scholars and several former general counsels of the Council on Environmental Quality.

The court is expected to hand down a final decision in the case by June.

Watch For Sulfur Deficiency In Alfalfa
Agronomy researchers at Purdue University are warning farmers in the Upper Midwest to be on the alert for signs of sulfur deficiency in alfalfa, corn and wheat later this growing season.

Researchers Jim Camberato and Shaun Casteel say the problem stems from the fact that power plants have reduced sulfur emissions in recent years. Atmospheric sulfur deposition used to be substantial enough to satisfy crop needs in many areas. They add that the incidence and severity of sulfur deficiency will likely increase. Sulfur deficiency is most likely in sandy soil with low organic matter, but can also occur in silt loam soil with moderate organic matter levels.

Sulfur-deficient crops typically have an overall yellow appearance, similar to nitrogen deficiency. But since sulfur is not as mobile in the plant as nitrogen, lower leaves do not show more severe deficiency symptoms than the upper leaves. The researchers add that, if sulfur deficiency is misdiagnosed as a nitrogen deficiency, applying nitrogen fertilizer will make the sulfur deficiency worse. For that reason, they recommend tissue sampling to positively identify the limiting nutrient.

To correct sulfur deficiency, the agronomists recommend applying sulfur fertilizer as close to crop need as possible to reduce the chance it will be lost from the root zone via leaching. Often, including sulfur in a fertilizer to head off a deficiency is more efficient and less costly than correcting a problem once it occurs. Typically, soil applications of 15-40 lbs of sulfate-S per acre are sufficient to prevent a deficiency.

Beat Rain Damage With Inoculants
Hay inoculants can definitely be worth a closer look for hay growers struggling to get their crops put up without spoilage due to rain, says University of Nebraska Extension forage specialist Bruce Anderson.

Legitimate hay inoculants contain bacteria and sometimes yeast or enzymes that can reduce the growth of microorganisms that cause hay to mold and spoil. “Be sure to use hay inoculants, not silage inoculants, as the latter rarely work on hay,” advises Anderson.

He adds that inoculants work best when hay is baled at the highest moisture possible for safe storage without additives. Since windrows have uneven moisture and moisture estimates aren't perfect, inoculants often protect against small errors and allow you to bale hay that is three to five points higher in moisture than would normally store safely. “Inoculants tested in university-controlled studies failed frequently when moisture was over 25%.”

  • A nationwide uptick in milk production, coupled with plentiful stocks of most dairy products, will limit milk price increases for dairy producers over the next few months, according to the April USDA Livestock, Dairy and Poultry Outlook. But rising export prospects and improved domestic demand could lift prices by year’s end.




State Reports: Mississippi, South Dakota
Mississippi
A spurt in ryegrass growth throughout most of the state in the last six weeks or so has taken pressure off hay supplies, reports Mississippi State University Extension forage specialist Rocky Lemus.

Ordinarily, ryegrass comes out of dormancy toward the end of December in the southern part of the state, in mid-January in the north. “This year, though, we had an extremely cold and wet winter,” says Lemus. “It didn’t start growing in many areas until late February-early March. We were a good six weeks behind.”

The production slump set off a scramble for hay; the state hay directory was flooded with calls. Now, though, the grass has come on to the point where livestock producers have enough of a surplus to start making hay and baleage.

Lemus adds that bahiagrass and bermudagrass are also coming on in the state’s southern regions. “Most people are expecting a good year for hay production. Our extended weather forecast is for normal rainfall. Last year, we had a very wet late summer-early fall and a lot of people couldn’t get that last cutting.”

To contact Lemus, call 662-325-7718 or email rlemus@ext.msstate.edu.

South Dakota
Following a long, snowy winter, spring has sprung big-time in southeastern South Dakota, reports hay grower Amy Freeburg, Gayville.

“We went into the winter wet, and we had a lot of snow all the way through February,” says Freeburg, who partners with her husband, Gary, at Freeburg Hay Farms. “We thought we might have some problems with flooding on our secondary roads and muddy fields once we got into the thaw. But it didn’t turn out that way. Right now, everything seems to be set up in really good shape for the growing season.”

In a typical year, the Freeburgs put up nearly 2,500 acres of hay. Most of it is pure alfalfa, marketed to dairies of all sizes from South Dakota east. They also market grass-alfalfa hay. The majority of their hay is packaged in 3 x 3 x 8’ bales.

With the favorable weather, they were able to seed 900 acres of alfalfa during the week of April 13. Barring a late frost, they could be on track to take a first cutting of alfalfa by mid-May, just a shade on the early side. “We haven’t had a lot of rain, but we didn’t really need it. We got some free nitrogen from all that snow this winter, and that’s helped everything green up. So far in April, we’ve only had one morning where the overnight temperature was below freezing. But here, you never know. It can still freeze all the way into May.”

To contact the Freeburgs, call 605-267-4426 or email freeburghay@iw.net.

Insect Update

Check Timothy For Mites
Damage to timothy from timothy mite feeding may have been reduced a bit in Pennsylvania this spring by unseasonably warm temperatures. But growers should still scout their fields for signs the pest is present, says John Tooker, Penn State University entomologist.

“Look for leaf blades that are rolled up tightly,” says Tooker. “The mites are microscopic and challenging to see even with good magnification.”

He recommends treatment if 25% of tillers show leaf curling within several weeks of green-up. While chemical options are limited, Sevin XLR has a supplemental label allowing its use against mites on timothy in Pennsylvania.
