Prescribe Your Water | Variable-Rate Irrigation Applies Rates by Soil Type, Topography, Yield goals 6

Tim Schmeeckle is learning to grow corn with less water. Precision-irrigation management is helping him and other farmers apply the right amount of water on every part of the field. Variable-rate irrigation (VRI) adjusts water application depth for differences in soil water-holding capacity, topography and yield potential.

Cash Rent on the Auction Block | Rent Auctions Give More Farmers a Shot at Renting Land, But Make Transaction Details Public 1

Cash rent went on the auction block in several areas around the Midwest last fall and winter. In Iowa, 3,300 acres of cropland brought rent bids ranging from $325/acre to $520/acre, stunning some market watchers. In southern Minnesota, several cash rent auctions last fall brought over $400/acre. In eastern South Dakota, bids at rent auctions in September and October reached $300/acre or more.

Find Your Resistant Weeds | Learn Early Warning Signs of Glyphosate-Resistant Weeds 2

One reason glyphosate-resistant weeds are multiplying is lack of early detection. Because glyphosate has been so effective, busy farmers often skimp on scouting after spraying, says Jeff Stachler, Extension weed scientist at North Dakota State University and the University of Minnesota. As a consequence, “we’re not detecting weed changes from year to year.”

Buffer Booster | Cut Nitrates by Routing Tile Water Through Grass Buffer 5

Directing tile water through a grass buffer can significantly improve drainage water quality. This new conservation drainage practice, called a “saturated buffer,” removes nitrates from subsurface drainage water at low cost – without affecting farm field drainage.

Wind Wisdom | 5 Questions to Ask Before Signing a Wind-Energy Lease 2

Leasing your farmland for wind power offers another source of income — one that lets you continue farming the land. But wind agreements create complex legal and financial issues, and affect your property rights far into the future, says Jennifer Jambor-Delgado, a staff attorney at Minnesota-based Farmers’ Legal Action Group.

More Aphid Ammunition | Soybeans with Genetic Aphid Protection Squelch No. 1 Soybean Pest

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.

Stray Corn Strut | Volunteer Corn Steals Beans and Feeds Your Worst Corn Pest

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.

Refine your Refuge | It's More Important Than Ever This Year

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.

Late June Soybean Success | Double-Crop Soybean Strategies From the 45th Parallel

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.

Tires or tracks? | What’s the Best Way to Avoid Soil Compaction?

Are tracks or tires better for reducing compaction from loaded grain carts? “The answer is, it depends,” says Randy Taylor, an Oklahoma State University Extension ag engineer.

Escaped Sediment Being Blamed on You | Conservation Practices have Slashed the Amount of Soil Moving from Farm Fields into Waterways

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.

Profit Perspective | Aerial Imagery Reveals Crop Problems Difficult to See from the Ground

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.

Slurry-Seeding Synergy | New One-Pass System Combines Light Tillage, Manure Application, Cover-Crop Seeding

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.
