FAU Lands $1.3M NSF Grant to Boost Dryland Soil Quality Amid Climate Stressors
Drylands, found across every continent, cover about 45% of the Earth’s land surface and support 38% of the human population. The NSF grant will enable scientists to enhance understanding of climate resistance of individual microbes and to improve microbial remediations to reduce soil degradation under climate change.
Although Tiny, Peatland Microorganisms Have a Big Impact on Climate
Polyphenols are generally toxic to microorganisms. In peatlands, scientists thought microorganisms avoided this toxicity by degrading polyphenols using an oxygen-dependent enzyme, and thus that low-oxygen conditions inhibit microbes’ carbon cycling.
Different Microorganisms Have a Taste for Different Flavors of Ammonia
Ammonia-oxidizing microorganisms (AOMs) use ammonia as an energy source while converting it to nitrite and play a pivotal role in the global nitrogen cycle. This study explored whether different AOM species preferred to use urea over ammonia. It found that some AOMs preferred urea while others used ammonia and urea simultaneously.
Between Soil and Society: New book traces history and development of U.S. conservation policy
A new book by a University of Illinois Urbana-Champaign expert in law and policy explores the history and development of the U.S. conservation policy, offering insight into how Congress works, how policy is put together, and the challenge of balancing narrow and public interests in addressing pressing agricultural and environmental topics.

Researcher studying worst western US megadrought in 1,200 years
Drylands in the western United States are currently in the grips of a 23-year “megadrought” and one West Virginia University researcher is working to gain a better understanding of this extreme climate event.
Researchers Directly Detect Interactions Between Viruses and their Bacterial Hosts in Soils
Bacteriophages are common in soil ecosystems, but many of these phages and the bacteria they target have not been identified.
Research team reveals the role of calcite in improving soil organic matter stability
A team of researchers led a study that has revealed valuable details about the role that calcite plays in the long-term stability of soil organic matter (SOM), which represents the Earth’s largest terrestrial carbon reservoir. Maintaining the stability of this reservoir…
Biological fingerprints in soil show where diamond-containing ore is buried
Researchers have identified buried kimberlite, the rocky home of diamonds, by testing the DNA of microbes in the surface soil.
Roots of Bloody Mary
Regardless of how one says ‘tomato,’ they all contain tomatine, a toxin in the plant’s green fruit, leaves, and roots. Tomatoes produce the bitter-tasting compound — a major plant-specialized metabolite secreted from the roots — to defend against pathogens and foragers.
Soil Salinity: Wild Grapevine Defends Itself
Climate change increases the need for artificial irrigation of agricultural areas. When water evaporates, however, salts remain in the upper soil layers and increase the plant’s stress.
New study shows saltwater intrusion is wreaking havoc on farms throughout Delmarva
A new paper from researchers at UD, the University of Maryland and George Washington University published in Nature Sustainability shows the spread and cost of saltwater intrusion from 2011-2017 in farms located in those mid-Atlantic states. The paper highlights how between the years 2011-2017, the area covered by visible salt patches almost doubled, with over 19,000 acres converted to marsh. Potential economic losses from the salt patches during that time period totaled over $427,000.
Soil microbes help plants cope with drought, but not how scientists thought
In a multi-generation experiment, researchers from the College of Agricultural, Consumer and Environmental Sciences (ACES) found microbes helped plants cope with drought, but not in response to plants’ cries for help. Instead, the environment itself selected for drought-tolerant microbes. And while those hardy microbes were doing their thing, they just happened to make plants more drought-tolerant, too.
UC Irvine receives grant to study lead exposure effects on children’s learning, behavior
The Program in Public Health at the University of California, Irvine has received a five-year, $2.7 million grant from the National Institute of Environmental Health Sciences to research the connection between low-level lead exposure during pregnancy and early childhood and children’s school performance and behavior in Santa Ana, California.
How much nitrogen does corn get from fertilizer? Less than farmers think
Corn growers seeking to increase the amount of nitrogen taken up by their crop can adjust many aspects of fertilizer application, but recent studies from the University of Illinois Urbana-Champaign show those tweaks don’t do much to improve uptake efficiency from fertilizer. That’s because, the studies show, corn takes up the majority of its nitrogen – about 67% on average – from sources occurring naturally in soil, not from fertilizer.
