Bacteriophages are common in soil ecosystems, but many of these phages and the bacteria they target have not been identified.
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…
Researchers have identified buried kimberlite, the rocky home of diamonds, by testing the DNA of microbes in the surface soil.
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.
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.
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.
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.
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.
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.
Plant life and soil conditions impact tidal marsh carbon storage
Soil microbes decompose organic matter into simple carbon compounds – what soil conditions do these microbes prefer and where do they work most efficiently?
Electrical conductivity sensors were able to predict soil texture – especially at different depths – and correlated with corn yield data
