Continuous corn yield boost? 2

You may not have to settle for yield drag with continuous corn. Recent University of Minnesota research indicates that yields from continuous corn in conservation tillage may be comparable to corn following soybeans or intensive tillage when selected management and products are used.

Corn research targets less nitrogen use 1

Substantial yield bumps from new nitrogen-efficient hybrids should come towards the end of this decade and early in the next one, says Michael Clements, Monsanto corn intrinsic yield and nitrogen lead.

New soil test tracks microbial activity

What if you had soil data that told you how much food was available for your soil microbes that build soil health? Well, a new soil test is gaining early traction among cover-crop users and no-tillers who reap the benefits of healthier soil, but truly lacked the right test to tell them about their available nutrients.

Corn rootworm management challenge grows 1

Discovery of root feeding and lodging in first-year Cry3Bb1-protected corn in central and east-central Illinois is only one of several scenarios adding to the challenge of corn rootworm (CRW) control in areas of the Corn Belt. The increasing complexities are leading more growers to consider a layered approach.

Adapt-N tool calculates for weather extremes and soils 15

Harold van Es knows how to make the best of a bad thing. The Cornell University professor of soil and water management couldn't have asked for better weather to test his team’s Adapt-N nitrogen application model in 2012 and 2013. Extreme drought last year followed by extreme moisture this year proves the program's value in ways moderate weather never could.

Moist Soil Sample Provides Precision, Better Accuracy in Estimating Potassium 1

Ignored for decades, moist sample analysis saves money and boosts yields. Soil labs and scientists alike abandoned field moist soil sampling decades ago. Common until the 1980s, field moist soil sampling was replaced with a faster and easier "dry and grind" procedure.

Scout for Weeds, Pests in Corn, Soybeans Early, Often, Walking the Field 10

"There’s nothing about scouting a farmer can't learn," says Bruce Potter, Minnesota Extension integrated pest management specialist. He, along with Ryan Wolf and Harold Watters scout extensively and train growers, crop consultants and agronomists how to scout. Scouting isn't just identifying a disease or insect pest, says Watters, an Ohio State University Extension field agronomist.

North Dakota Corn Yield Trials Have Success with Conventional Corn Hybrids 16

GM hybrids aren't the only "elite" germplasm. G2 Genetics' 3-H-399 AgrisureRW hybrid, with a full complement of GM (genetically modified) traits, captured headlines with a record 309.5 bu./acre yield in the North Dakota University (NDSU) irrigated corn trials. However, the conventional hybrid runner up may suggest an even bigger story.

Secure Your Landlords | Status Quo Land Leases May Cost You Lost Acres 4

How secure is your relationship with all your landlords? At a time when aggressive operators are targeting long-term relationships, offering substantial bumps to rental agreements, what would your landlords accept? Do you know how to 'seal the deal' with every landlord?

Drought-Beater Soybeans 1

While the drought ravaged many Midwestern corn fields in 2012, soybeans in many of those same areas broke yield records. Field averages of 70, 80 and 90 bu. with spikes well above that were reported throughout the upper Midwest. Extension crop specialists contacted by Corn & Soybean Digest credit the ever-resilient soybean's response to late-season rains. And to the role the hot dry weather played in reducing insect and disease pressure.

Size is No Excuse | Large Farmers Make Cover Crops Work 4

If you think cover crops are for smaller operators only, don't tell Mark Anson and Lanny Greenhalgh. Anson sees them as an integral part of his family's 20,000-acre farming operation. For Greenhalgh, who farms several thousand acres near Guide Rock, Neb., cover crops build soil, retain moisture for higher yields and allow custom grazing.

Landlord Shock | Farmers Learn New Perspectives From Next-Generation Landlords 3

Farmers aren't the only ones getting older. Forty-two percent of non-operating landlords (NOLs) were more than 70 years of age in 1999*. As control of rental property shifts to the next generation, long-term tenant relationships can shift, too.

Crop Sensors Come of Age | Farmers Prove Technology Can Deliver Comfort, Payback 4

In-crop optical sensing, also called canopy sensing, is boosting yields and cutting costs for Robert Goettl, his brother Jerome and nephew Justin. Their GreenSeeker crop sensing system allowed the Le Center, Minn., farmers to shift away from reliance on all fall nitrogen (N) application. For the past four years they have combined a base fall rate with variable in-season applications using a coulter cart. Yields were up 10 bu./acre or more in the drier-than-normal 2012 season.

Biologicals Enter the Mainstream | Better Technology Increases Understanding of How Biologically Based Crop Inupts Work 1

Biologically based crop inputs are moving from the orchards and cabbage patch to corn and soybean fields. A combination of higher value commodity crops, synergies between biologicals and synthetic chemical controls, new research tools and major corporate investments are driving the trend.

The Auto Copter offers multiple sensor capabilities for crop scouting.
Tiny Planes Coming to Scout Crops 8

Dale Crawford has his own crop-scouting drone...sitting in the basement. The Sullivan, Ill., corn and soybean grower bought the Canadian-built, CropCam fixed-wing-style, unmanned aerial vehicle (UAV) after seeing one at Commodity Classic about five years ago. He was intrigued by the idea of doing aerial photos for his fields and possibly others.
