Water is of growing concern to people in the Great Lakes region, especially after this summer’s widespread drought. Now, researchers are testing a device that could help Midwest farmers decide the best way to manage their water. The Great Lakes Radio Consortium’s Rebecca Williams has more:
The device is called an electron moisture sensor. It measures the amount of moisture in soil, as deep as 3 feet below the surface. The sensor is hooked up to a hand-held computer that brings together soil data with information about weather and the type of crop being raised.
Rich Hoddup is an agriculture extension agent with Michigan State University. This year, he recruited several farmers to test the moisture sensor. He says the farmers are reacting to the system with optimistic caution.
“They’re looking at it and saying, well, it’s kinda nice to be able to understand what’s going on below the soil profile, rather than waiting until that crop begins to show symptoms of drought.”
Rich Hoddup thinks the sensors may allow farmers to increase their yields, by telling them when and where to add water to their crops. He plans to continue his research to see if the benefits to farmers will outweigh the high cost of the system.

A new study published in the journal Nature indicates that farmers could save fertilizer costs and pollute less while producing the same harvest. The Great Lakes Radio Consortium’s Lester Graham reports:
Researchers at the University of Illinois studied the use of nitrogen as a fertilizer on crop fields in the Mississippi River basin from the 1950’s to the 1990’s. Based on what they found, they think farmers could have reduced nitrogen fertilizer use by a relatively low 12 percent and kept harvest yields the same, yet reduced nitrate levels in the Mississippi river by a relatively high 33 percent. That might have significantly reduced the so-called dead zone in the Gulf of Mexico where the Mississippi carries the nitrates. Gregory McIsaac is the principle author of the study. He says farmers could reduce nitrogen use if for no other reason than saving money.
“Farmers have been applying more nitrogen than they need and they can reduce their fertilizer application and be better off, whether or not it has any impact on water quality.”
McIsaac notes a survey conducted last year found about 30 percent of Illinois farmers indicated they use more nitrogen than is recommended, hoping for better crop production.

Canada Geese take flight.

Canada Geese are about as common as the green lawns they like to hang out on. But at one time they’d almost disappeared from the region. Thanks to successful wildlife management efforts, the goose is back, and now the question is how best to manage a success story that some say has been too successful.

Canada Geese are about as common as the green lawns they like to hang out on. But at one time they’d almost disappeared from the region. Thanks to successful wildlife management efforts, the goose is back, and now the question is how best to manage a success story that some say has been too successful. The Great Lakes Radio Consortium’s Dan Gunderson has more.
In 30 years, the giant Canada goose was on the verge of extinction, but the species has made a comeback that amazes biologists. There were just about enough for a gaggle when humans stepped in to help in the late 1960’s, now numbering in the millions today, the goose is a wildlife management success story that won’t stop.
“We’ve spent millions and millions of dollars to bring the population back.
Now it’s high and it’s eating everything in sight.”
Standing on the edge of a waist high soybean field on his Minnesota farm, Chad Jetvig points to a slough about a quarter mile away. It’s obvious where geese feasted on tender young soybean plants early this summer, leaving large bare spots in the field.
Jetvig says he’s always accepted some crop loss from geese as a part of farming among the prairie potholes of western Minnesota, but he says the amount damage is no longer acceptable.
“I would say in the past two years in particular, but it’s been getting worse each year, we’ve started to see huge areas. Just on this one single farm at two hundred acres that’s over 40 thousand dollars right just out of our pocket. That’s a lot of money.”
And thousands of farmers in the Midwest and Northeast U.S. have similar stories.
This year and last, Chad Jetvig has gotten a permit to shoot geese eating his crops, but he says it’s an exercise in futility.
“We came out here and shot one time and the next time you even drive by they’re gone. They’d even know the color of the pickup. If this one blue pickup we’re using came around, they seen that thing, whoosh, they’re gone.”
Only to return as soon as the coast is clear. Those keen survival instincts are one reason for the goose population explosion. There’s also plentiful food provided by farmers like Chad Jetvig, and lots of wetland nesting sites.
There are an estimated 2 million giant Canada geese in the upper Midwest and Northeast that’s far more than biologists like Minnesota Department of Natural Resources, goose expert, Steve Maxson think is ideal.
“I think a lot of biologists are wondering just how high this population can go. It’s already exceeded their wildest dreams I think and it seems even in the face of intense hunting pressure to be increasing in most areas. I guess the bottom line is we just don’t know how high this population can get.”
Biologists rely on hunting to keep many wildlife populations in check, and the Canada goose harvest has steadily increased along with the population. But Maxson says simply allowing hunters to shoot more birds is not the answer. The birds quickly learn how to avoid hunters. Then there’s the eastern prairie goose that nests in northern Canada and migrates through many states in the region. The eastern prairie goose population is much smaller and less robust than the giant Canada, and biologists fear expanded hunting could destroy the species.
The U-S Fish and Wildlife Service draft environmental impact statement due out this fall will offer several population control alternatives. They range from no action, to targeted hunting in areas where geese are in conflict with humans, to extreme measures such as, destroying nests and eggs. Steve Wilds is the Fish and Wildlife Service regional migratory bird and Chief. He says it’s critical a workable plan come out of this process. If not, he fears future management decisions will be political, not biological.
Wilds says the future of the giant Canada goose is at stake.
“So that they’ll continue to be recognized as a tremendous, beautiful part of our natural landscape and yet not something that’s going to be doing so much damage people start thinking of them as vermin rather than really neat critters.”
The Fish and Wildlife plans to take a public input on its goose management plan early next year. Steve Wild says it will be at least a year before any final decision is made on how the Canada goose populations will be managed in the future. For the Great Lakes Radio Consortium, I’m Dan Gunderson.

When was the last time you got a bouquet of flowers that had a fragrant smell? While there’s no shortage of beautiful looking flowers for sale, many have little, if any, scent anymore. Ast he Great Lakes Radio Consortium’s Tamar Charney reports, it’s a problem one scientist has gotten a whiff of:
Flowers have lost their smell as flower growers have bred them to be big and brightly colored. Eran Pichersky is a biologist at the University of Michigan. He studies the smell of flowers. Pichersky is focusing his genetics research on whether it’s possible to bioengineer a flower’s scent.
“We actually have some collaboration with biotech companies who are trying to use some of the genes and enzymes we’ve isolated to put them back into plants so that the plant makes more scent, or even new scent that they didn’t make before.”
But it’s not florists who are interested in this work, it’s farmers. Pichersky’s research means it might be possible to alter the smell of flowers in ways that entice bees to visit crops more often, or even attract other insects to do the pollination work. That increase in pollination could mean an increase in crop yields.

Cranberries are a well-established crop in Wisconsin, but other Great Lakes states are looking to grow the berry as well. On the eastern shore of Lake Ontario, farmers are hoping to take advantage of the heavy lake effect snows to cut the cost of growing the crop. The Great Lakes Radio Consortium’s Eugene Sonn reports:
