Farmers in Iowa are studying interactions between crops, water usage, carbon and nitrogen storage, and how those factors combine to affect longterm soil biodiversity. It's part of a seven-state project in the Midwest.

Researchers are looking at the effects of crop combinations on soil and moisture across the Corn Belt.

Iowa State University Agronomy Professor Sotirious Archontoulis is running one research site in the five-year, $16 million project.

He's monitoring how crop management, carbon and nitrogen content affect soil moisture - and will try to predict the impact on the viability of future crops.

"We have the same setup in many different environments to capture different organic matter, soil hydrology conditions," said Archontoulis, "so we get a better understanding of the complexities in the agronomic system."

Archontoulis said scientists can also study greenhouse gas emissions from the soil.

He said these ultimately affect its health and can have an impact on large ag operation waste runoff, which is known to pollute nearby ground and surface water. The research is gearing up now.

Based on the computer model's findings, Archontoulis said researchers can make recommendations to farmers based on - for example - how much nitrogen the soil is losing in certain places, and how they can adjust planting schedules as a result.

"We can say, 'This cropping system with this management practice typically loses that amount of nitrogen,'" said Archontoulis. "'However, the other combination of cropping system could reduce nitrogen loss and improve productivity by X%, so this is a better strategy to move forward.'"

Archontoulis said the research begins across the Midwest this summer.

West Virginians are more concerned about bird flu's effect on grocery costs rather than health implications, and Republican voters are more likely to distrust Centers for Disease Control and Prevention information about the virus, according to a new poll from the health policy research and news organization KFF.

Nearly nine in 10 adults across parties, race and ethnicity, and household income levels are "very" or "somewhat" concerned bird flu will increase the cost of food in the U.S.

Audrey Kearney, senior survey analyst for KFF, said rising economic pressure has households more worried about paying for housing, gas, transportation and everyday expenses.

"We found that only half of the public said that they are really hearing a lot about bird flu on a day-to-day basis," Kearney reported. "It might not be resonating in the way of health but it definitely is resonating in when they go grocery shopping."

Since 2022, officials have identified just two backyard flocks, around 260 birds, in the state affected by the virus. Earlier this year, the West Virginia Department of Agriculture issued a suspension on all poultry exhibitions and sales statewide, calling the move a precautionary measure.

Kearney added one of the biggest takeaways from the data is Americans now have different levels of trust between community experts they are interacting with on a daily basis, and major institutions.

"Messages from people's doctors are going to be the most well received and probably the most effective on that front," Kearney explained.

Currently, the CDC recommends people avoid close contact with sick animals and avoid unpasteurized milk products as precautions against bird flu, while eggs purchased from grocery stores are considered safe.

Since April 2024, 70 human cases of bird flu have been reported in the U.S. Of those, 41 cases were associated with exposure to sick dairy cows and 26 were associated with exposure to poultry.

New Mexico may never be a leader in aquaculture but some fish farmers are finding success in the arid state.

Rossana Sallenave, professor and extension aquatic ecology specialist at New Mexico State University, said the U.S. is among the top five consumers of fish and shellfish. She believes aquaponics, used to raise large quantities of fish and plants in relatively small volumes of water, is highly suited to promoting sustainable agriculture.

"I think the future here in New Mexico is recirculating systems," Sallenave explained. "Because we are running out of water and that's the area of aquaculture that is really gaining some traction here in New Mexico, particularly aquaponics."

Sallenave pointed out New Mexico's unique environmental and biological resources include 15 billion acre-feet of saline water. She noted it cannot be used for traditional agriculture or for drinking water but could be used for aquaculture. Global demand for seafood is projected to increase by 70% in the next 30 years and experts believe a dramatic increase in aquaculture could help supply food needs.

According to Sallenave, aquaculture, like most farming enterprises, is highly risky because many variables must be controlled over a long period to produce a marketable crop. If control is not maintained, a crop can be lost, resulting in substantial financial losses. But she emphasized it can be a viable enterprise for those willing to educate themselves, keep abreast of new technologies and apply what others have learned. And compared to traditional agriculture, aquaponics requires significantly less fresh water.

"You can grow protein and you can grow plants in a small recirculating system which needs very little water," Sallenave outlined. "Just topping off a little bit weekly to replace evaporative losses."

Sallenave added the site selected for an aquaculture enterprise, which must meet the biological criteria for the species proposed, has a significant effect on an operation's viability. One New Mexico success story is AmeriCulture near Animas, which started producing Nile tilapia commercially more than a decade ago using geothermally heated greenhouses in pure well water from a desert aquifer.

A bill in the Idaho Legislature would lower restrictions for allowing chickens in residential areas.

The impetus for the legislation from Sen. Tammy Nichols, R-Middleton, is in part high prices and the shortage of eggs at the grocery store. Senate Bill 1026 would ensure that homeowners associations could not bar residents from raising up to four chickens per one-fifth of an acre.

"Most people eat more than four chickens a year," said Ariel Agenbroad, who focuses on food systems and small farms at the University of Idaho Extension, "but for egg laying, if a chicken is laying an egg every other day, that can be a significant number of eggs that can be used by that family or that household."

While raising chickens could offset egg costs in the long run, Agenbroad notes there can be substantial upfront costs to the birds. Critics of the bill have said the chickens could potentially disrupt neighbors. Other concerns include noise, odor and the spread of diseases such as salmonella, to name a few. The legislation has passed out of the Senate and moved on to the House.

Agenbroad said people aren't going to get rich raising a small number of chickens in their backyards.

"Policies like this can have a really positive impact on people's ability to be self-sustaining," she said, "but I don't see it having a lot of impact on small business, like entrepreneurship or our farm business development, because the numbers are so small."

Agenbroad said it could pique someone's interest in farming, however. And beyond their value as farm animals, she said as a former chicken owner herself, the entertainment value alone is worth it.
