Two genes that help soybeans fend off aphids worked well in 2011, both as single and stacked traits. That’s according to a six-state study of soybeans with aphid resistance genes, known as Rag1 and Rag2. Individually, the genes slowed aphid growth significantly, says Iowa State University entomologist Matt O’Neal, who led the research.
On a road trip last September through Minnesota, Wisconsin and Iowa, Jeff Gunsolus was struck by all the volunteer corn sticking up out of ripening soybean fields. “It seems that people aren’t valuing this as a weed-management issue," says the Minnesota Extension weed scientist. Many growers are not killing it soon enough as volunteer corn is very competitive with soybeans, he says.
Minnesota farmer Gene Stengel and his sons Kevin and Rob will plant a 20% insect refuge this spring, as usual. Although “refuge-in-the-bag” blends of Bt and non-Bt seeds are proving popular with farmers – and could predominate in coming years – many growers will still plant structured non-Bt refuges in 2012.
Come end of June, Minnesota grower Norm Giese will be planting soybeans again, just like he has done for the last 13 years, successfully. The Appleton, MN, farmer and his son and son-in-law grow 5,000 acres of corn, soybeans and dry edible beans. They also grow 350 acres of fresh peas for a local processor.
This spring, a muddy lake on the Mississippi River sparked a flurry of controversy about agricultural drainage. Lake Pepin, on the Minnesota-Wisconsin border, is filling up with silt. Most of the sediment is carried into the lake by the Minnesota River, a turbid prairie river that meanders through some of the most productive – and heavily tiled – cropland in the world.
For a new view of crop production, try rising above it all. Aerial images of fields are useful tools for detecting crop variations and equipment problems that are hard to see from the ground, says Tom Oswald, a Cleghorn, IA, farmer who’s used aerial imagery for several years.
Manure and cover crops are a natural combination, but livestock farmers are often too busy in the fall with harvesting and manure application to worry about putting in a cover crop. Now, a new seeding technique makes it more practical for Midwest growers to reap the benefits of cover crops without an extra field pass. Slurry seeding combines liquid manure injection, low-disturbance tillage and cover-crop planting – all in one efficient operation.
More northern Corn Belt farmers are planting continuous corn, and that means more hard-to-handle residue left in fields. Higher plant populations, better-yielding hybrids, less aggressive tillage and the cold climate – which slows down decay – all increase the mounds of debris.
Iowa grower Jay Johnson recently sold a farm – but he didn’t quit farming it. Johnson raises about 2,000 acres of corn and soybeans with his brother Steve at Stratford, IA. In June 2010, Johnson bought a 72.5-acre farm, paying just over $6,100/acre.
Would you pay more cash rent than you had to? John and Jack Scott did. In January, following an excellent year for crop yields and prices, the Gilby, ND, farmers sent a voluntary cash bonus to their landlord, John Botsford, Grand Forks, ND.
The run-up in cash rents prompted two Red River Valley farmers to join forces to stay profitable. Gaylen Affield and Jared Nordick raise corn and soybeans in the rich glacial soils of ancient Lake Agassiz, along the Minnesota-North Dakota border. The Wilkin County, MN, growers also operate two successful farm-related businesses together – a Precision Planting dealership and an excavation service. After both men lost leased cropland to rising cash rents, they teamed up on their farming operations, too.
Does setting cash-rental rates feel a little like playing roulette? Can you guess the winning number? Surging farmland values and volatile crop and input prices are complicating next year’s cash-rent decisions – and intensifying risk.
