Invasive plants can remove excess salt at the roadsides

,
Some plants help clear roadsides of salt and pollutants, a research has found. But their contribution is not enough. De-icing applications need to be reduced

This is how climate change will alter U.S. agriculture

,
Climate change is set to impact agricultural yields in the U.S. Midwest, a study by the University of Connecticut says. "Data suggest a 12 percent decrease in corn yields by around 2050 and 40 percent by the end of the century"
In many cities in the United States and Canada, municipal waste incinerators were largely shut down in the 1970s in the face of growing concerns about air pollution. Photo: Fraser, Clayton B.

Waste incineration leaves a heavy legacy in soils

,
Where waste was once burned, higher concentrations of lead are detected in the soil, says research from Duke University. With obvious health consequences
In addition to economic benefits, the reduced use of nitrogen fertilizer also has environmental benefits.

Deep soil testing reduces fertilizer spending

,
A study from Texas quantified the average savings associated with reducing fertilizer use after soil testing. For a 1,000-acre U.S. farm, it exceeds $130,000 per year

Solar farms may encourage soil erosion in U.S.

,
Virginia Tech researchers will analyze erosion risk in the state's solar installations. In the U.S., the problem is real. But several solutions are available
The application of cover crops under the vines allows the plants and soil protection by reducing the use of herbicides. Photo: ד "ר יהודה מלמד עין הוד Attribution-ShareAlike 3.0 Unported (CC BY-SA 3.0)ד "ר יהודה מלמד עין הוד Attribution-ShareAlike 3.0 Unported (CC BY-SA 3.0)

Cover crops are a sustainable solution for vines

,
In vineyards, competition from cover crops can be used to limit the exposure of vines to disease, a study by Penn State University says. In this way the use of herbicides is reduced

Polyethylene mulches leave behind ‘negative effects for decades’

,
L’ampio utilizzo delle pellicole da pacciamatura nelle colture di fragole si traduce nella dispersione di micro e macro frammenti di plastica nel suolo. Un fenomeno, rivela uno studio californiano, i cui effetti possono manifestarsi per decenni
U.S. Geological Survey researchers have developed a new remote sensing system to detect deforestation on large geographic and temporal scales.

New developments in deforestation remote sensing in the U.S.

,
By combining old deforestation survey methods, U.S. Geological Survey researchers have developed a new large-scale representation which increases efficiency and accuracy. The hope for the future is real-time mapping

Microbes give new hope for soil remediation in Alaska

,
Alaska, which has always struggled with cases of oil contamination, may find new solutions in phytoremediation. According to researchers at the University of Fairbanks, grasses and fertilizers shape microbial communities responsible for disposing of toxic substances
Per- and polyfluoroalkyl substances are typically found in fluorinated pesticides that contain one or more fluorine atoms in their molecular structure and are considered particularly effective in combating plant pests.

Worrying data in the U.S. on PFAS contamination in soil

,
In New Hampshire, the presence of fluorine-based substances was detected in all soil samples taken by researchers. These products, known as PFASs and contained in pesticides, are typically difficult to dispose of
