Study warns fish lovers of multiple chemicals

LANSING — A new study questions whether public health advice on eating Great Lakes fish is restrictive enough.

Ken Drouillard, a professor at the University of Windsor, looked at whether the Great Lakes region recommends sufficient restrictions on monthly meals of sport fish.

The results are in, and while they say no, they weren’t as restrictive as Drouillard expected.

Consumption advisories are used to limit human exposure to harmful substances that fish may contain.

Drouillard found that 60 percent of advisories would provide more restrictive advice under a method that takes into account multiple chemicals in a fish. That’s contrary to the current practice of basing fish advisories on just a single contaminant, according to the study published in the Journal of Environmental Health Perspectives. Continue reading

Farmers uninterested in renting land for bioenergy crops

LANSING — When Scott Swinton, an agriculture, food and resource economics professor at Michigan State University, asked landowners if they’d be interested in renting their land for bioenergy crops, the initial response was unexpected.

“The first thing we found was that a number of people that we sent questionnaires to were hoping MSU was secretly trying to find people they could rent land from to grow bioenergy crops,” Swinton said.

“I got scores of phone calls from people telling me they would love to rent their land to MSU if we were interested.”

But that wasn’t what Swinton was looking for. Instead, he was trying to study the willingness of farmers to rent land that isn’t used for crops. Continue reading

Seed-stealing bugs threaten prairie restoration

LANSING — Bugs hinder prairie restorations more than previously thought, according to research conducted at Michigan State University.

The study found that arthropods — which include insects, spiders and crustaceans — account for the majority of seeds removed from prairie restoration sites.

The study could catch a lot of attention in the prairie restoration field, said Mary Linabury, an MSU plant biology researcher who authored a study to be published in the Journal of Plant Ecology.

“In the past, I don’t believe that managers believed that arthropods had much of an impact on seed consumption,” said Linabury, who conducted the research with Lars Brudvig and Nash Turley of MSU. “This study says otherwise.” Continue reading

Cows and deer that share salt might also share disease

LANSING — A popular source of nutrition for cattle is a potential site for transferring disease, according to a recent study.

Salt blocks are potential transmitters of tuberculosis from cow to deer and vice versa, said John Kaneene, the lead researcher of a study by Michigan State University’s Diagnostic Center for Population and Animal Health.

The blocks are commonly placed in pastures for cattle to lick. At night, deer can enter the field and lick the same salt.

The study found that if a deer or cow is infected, it can leave that disease on the salt block for the next animal to eat.

“It’s a big finding,” said Kaneene, who is an epidemiology professor at MSU. “We kept on saying, ‘Despite all these efforts, why are we having repeated infections on these cattle farms?’ That’s how we came to salt blocks.” Continue reading

Computer model bolsters sustainability, production for dairy farms

LANSING — Researchers at Michigan State University are creating a computer model to help make pasture dairy farming more sustainable.

The project draws upon several research papers released in the past three months that discuss the environmental impact of livestock farms and how climate change affects them.

They also address the challenges of moving cows from barns to pastures.

Mecosta, Sanilac and Hillsdale counties have more than 100 dairy farms each, according to the United Dairy Industry of Michigan. Allegan and Huron counties have between 76 and 100, while Gladwin, Missaukee, Newaygo, Montcalm, Ionia, Clinton and Isabella counties have between 51 and 75 each.

Pasture-based livestock graze year round or seasonally. That’s different than in confined systems where the cows are housed and fed indoors for the majority of the year, said Melissa Rojas-Downing, an MSU doctoral student and a co-author of the research papers. Continue reading

Productivity boost offsets acreage, price declines of corn

By CARL STODDARD

Capital News Service

LANSING — Soon Michigan farmers will start planting millions of acres of corn, cultivating what has become a billion-dollar business in the state.

Farming is one of the top three industries in Michigan, and corn one of the top crops.

“Agriculture in Michigan has been a growing industry, contributing a great deal to the state’s economy,” said Kate Thiel, a field crop specialist for the Michigan Farm Bureau and its 46,500 member farmers.

One of the largest crops in Michigan is corn, Thiel said. Michigan farmers grew about 2.4 million acres of corn for grain in 2016, generating $1.1 billion last year – despite a price drop.

“While corn growers have seen a decrease in value of their product in recent years due to decreased commodity prices, they still play a large role in Michigan’s economy,” she said. Continue reading

Fluctuating weather complicates harvesting for farmers

By LAURA BOHANNON

Capital News Service

LANSING — As the weather continues to fluctuate around the state, farmers are being forced to adapt to changing conditions.

Amanda Shreve, the program director for the Michigan Farmers Market Association, said farmers can adapt to virtually any weather condition. She also said that as a result of warmer weather for longer periods throughout the year, farmers markets open earlier in the year and close later than they used to.

“We used to have a general farmers market season of July – September, but now we see a lot of markets starting in May and going all the way through October or November,” Shreve said.

Some crops come in early as a result of the warmer temperatures, too. Maple syrup is set to come in about a month early, said Savannah Halleaux, a public affairs officer for Michigan’s Federal Service Agency in the U.S. Department of Agriculture. Continue reading

LANSING — Good news for Michigan vineyards: the time grapes have to ripen has dramatically increased over the past few decades.

“It’s nearly grown an entire month in just four decades,” said Steven Schultze, an assistant professor of geography at the University of South Alabama who discovered the shift as a doctoral student at Michigan State University.

“One of our biggest findings, just since 1971, the growing season in Southwest Michigan has increased by 28.8 days,” Schultze said. Continue reading

Insects could add protein to our diets

LANSING — Michiganders raised on meat and potatoes may soon notice a new high-protein food on their plates.

That is if entomophagy experts can convince people to eat bugs.

Michigan is among the areas where insect agriculture is expanding to meet the demands of a looming global food scarcity crisis, experts say. Wayne State University hosted the first North American conference on eating insects last May in Detroit. And a Detroit company is working with state regulators to launch the state’s first urban insect farm.  

The Food and Agriculture Organization of the United Nations (FAO) estimates the world’s population will grow to 9 billion by 2050. And it will take a big increase in food production to feed them all. Continue reading

LANSING — Some trout in Great Lakes tributaries are just as contaminated with a chemical linked to respiratory, liver and skin ailments as the Pacific salmon that they eat, according to a new study.

The findings should help those making decisions on eating fish, dam removal and stocking, according to the researchers.

Pacific salmon, such as Chinook and coho, are large sports fish that live most of their lives in the Great Lakes and then spawn and die in rivers and streams. Continue reading
