Roundup Ready Alfalfa EIS Coming Soon
By Neil Tietz, Editor, Hay & Forage Grower
Roundup Ready alfalfa seed could be back on the market in time for spring 2010 seedings, believes Matt Fanta, trait business manager for Forage Genetics International. He says the long-awaited draft environmental impact statement (EIS) on the biotech crop is expected to be published by USDA’s Animal and Plant Health Inspection Service (APHIS) by mid-September.

Following an expected 60-day public comment period, APHIS will prepare a final EIS. If the document shows that Roundup Ready and conventional alfalfa can successfully co-exist, and barring further legal action against the transgenic crop, it may once again be deregulated.

Minnesota Researchers Seek Grower Help
Two Minnesota researchers are recruiting alfalfa-corn growers to help with a research project aimed at reducing purchased fertilizer inputs.

Starting this fall, Jeff Coulter, University of Minnesota extension corn agronomist, and Michael Russelle, USDA soil scientist, will conduct on-farm research to investigate the effect of various management factors on the nitrogen credit from alfalfa to first-year corn. They’re looking for southern Minnesota alfalfa-corn growers who have three- or four-year-old alfalfa fields with stands of two or more plants per square foot that will be terminated after the growing season. The land area required for the research is approximately 1.5 acres. Ideally, fields will be located within 2.5 hours of the Twin Cities.

The researchers will require help from the growers to establish the regrowth treatments this fall. They’ll also require help to establish tillage timing (alfalfa termination) treatments this fall and again next spring. After spring plowing in 2010, growers will prepare the seedbed, plant corn and control weeds with their equipment, using the same production practices used within the rest of the field. (Exception: Manure and N fertilizer cannot be applied in the experimental area).

The researchers will take care of N fertilizer application and crop harvest in the experimental area. Cooperating growers will receive $500 this fall and an additional $500 in the fall of 2010. The Minnesota Corn Research and Promotion Council is providing funding for the project.

Interested growers can contact Coulter at 612-625-1796 or coult077@umn.edu or Russelle at 612-625-8145 or Michael.Russelle@ars.usda.gov.




Time To Evaluate Thinning Stands
Early August is a good time in many parts of the country to check established alfalfa stands to see if they need to be replaced with new seedings, says University of Nebraska extension forage specialist Bruce Anderson. Some steps to take when evaluating fields:
  • Count shoots. Older dryland fields with less than 25 shoots/square foot coming from two or three plants should be replaced. Very productive sites, such as irrigated and sub-irrigated fields, should have over 40 shoots/square foot from four to six plants.
  • Dig and examine plant roots. Healthy roots are solid and white, with a firm texture. Roots that are discolored in a third to half of the tissue might survive this coming winter, but the plants will not yield well next year.
  • Examine crowns and taproots. If they show extensive brownish discoloration or are becoming mushy and partly rotted, the plants probably won’t survive another winter.

Oats Into Wheat Stubble? Plant Soon
Following up wheat harvest by planting oats in mid- to late summer, or even into early fall, is a strategy worth considering for Ohio producers seeking additional forage production. That’s according to Stan Smith, Ohio State University extension program assistant in Fairfield County, and Curt Stivison, engineering technician with Fairfield Soil and Water Conservation District.

During seven years of research, Smith and Stivison report, oats planted into wheat stubble during July and August have consistently yielded 3+ tons/acre of dry matter. Even so, they note, yield and quality can vary greatly depending on planting date, nitrogen fertilization and oat varieties.

Among their observations and recommendations:
  • Optimum planting date for yield is the first week of August. Early August plantings also result in the highest total amount of TDN produced per acre. Later plantings will be slightly higher in quality, but not enough to offset the yield advantage of early August planting. While more conducive to mechanical harvesting in early fall, planting in early July reduces yield and quality. The earlier oat plantings also exhibit more susceptibility to rust.
  • Regardless of the planting date or variety, no-till seeding rates of 80-100 lbs of oats have consistently resulted in optimum forage yields.
  • Optimum nitrogen application rate is 40-50 lbs/acre. It not only produces the highest yields, but it’s also the most cost-effective rate at current nitrogen values. Higher rates of nitrogen actually appear to depress yields based on 2008 plot results.
  • The optimum combination of yield and quality of August-planted oats arrives 60-75 days after planting. Oats planted earlier mature more quickly and thus rapidly decline in quality beginning 50-60 days after planting.
  • Oats harvested 50-60 days after planting and while still in the boot stage of maturity will provide regrowth that may be grazed or sometimes even mechanically harvested a second time.
  • A weed-control application of glyphosate is a necessary and cost-effective practice prior to oat planting.

  • As of July 1, the number of cattle and calves in the U.S. totaled 101.8 million head, according to last week’s USDA Cattle Report. That’s down 1% from year-earlier levels. Beef cows, at 32.2 million, were down 1% from the July 1, 2008, figure, while milk cows, at 9.2 million, were down 2%. To see the full report, click here.




State Reports: Colorado, Minnesota
Colorado
It has been an extremely tough start to the haymaking season in northeastern Colorado, reports hay grower Don Leonard of Don’s Hay Service near Brush.

Wet weather was the major obstacle for first cutting. “We were coming off a drought this spring,” says Leonard. “Then the rains started, and they just didn’t quit. The harvest conditions were terrible at best. Some of our first crop was on the ground for 33 days. We eventually had to get it off, but the quality was next to nothing.”

Leonard puts up large square bales of alfalfa and alfalfa-grass hay on 450 acres of irrigated ground. He does custom harvest work – hay, wheat straw and cornstalks – on another 1,800 acres. He markets to dairies, feedlots and ranches.

The late start continued to hinder growers on second crop as well. “We had a lot of stripes where the windrows from first cutting had been laying so long. It really set back regrowth.”

As he looks ahead to third-crop harvest, Leonard points out that the weather still hasn’t returned to normal. “We’re still getting a lot of humidity, and it seems like there’s a chance of a thunderstorm in the forecast every day. We’re looking forward to some dry weather.”

If the weather eventually cooperates, Leonard expects top-quality hay will fetch a good price. “Premium- and supreme-quality hay are going to be in short supply throughout a big part of the region,” says Leonard, who’s also treasurer of the Colorado Hay and Forage Association. “We’ve heard reports out of Idaho, Utah and Wyoming, and they’ve been facing the same kind of thing we’ve been facing here. Demand will be there if we have product.”

Leonard can be reached at 970-380-2044 or donshay@kci.net.

Minnesota
Timely rains in mid-July will give a boost to third-crop haymaking in the central part of the state, reports Dan Martens, University of Minnesota extension educator for Stearns, Morrison and Benton counties.

“There are still a few people in the area picking away at second crop. But, for the most part, it’s all wrapped up,” says Martens. “And most people across the area have caught enough rain to give third crop a good start.”

Cool and dry weather crimped first-crop yields in the area slightly. “On the upside, we didn’t have any rain to speak of during harvest, so overall quality was very good. Second-crop yields were close to normal, and we had a weather pattern that allowed people to get it put up without rain. The quality should be good there as well.”

Being able to put up good-quality hay has been a bright spot for area dairy producers. “Given everything else they’ve had to deal with this spring and summer, they needed something positive.”

Martens notes that some hay growers have been reporting high populations of aphids following second-crop harvest. He suspects spraying for alfalfa weevil larvae between first and second cuttings may have killed some of the natural predators that ordinarily control the aphids. “That’s speculation on my part,” he says. “We don’t normally see many aphids here, so we’re all learning a little more about them and how to deal with them.”
