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

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
A causa dell'agricoltura moderna i tassi di erosione nelle praterie in Iowa, Minnesota, South Dakota, Nebraska e Kansas sono cresciuti di mille volte. FOTO: Austin Goode su Unsplash

USA, erosion runs 1000 times faster than normal

,
The discovery is contained in a thesis of master at Umass Amherst University. To calculate the rate of erosion, a team of researchers quantified the presence of a rare element - Beryllium 10 - in cultivated prairies in 5 US states, comparing them with virgin soils

Researchers in the U.S. launch five-year soil health survey

,
Four U.S. universities are launching a massive soil analysis project. The initiative aims to counter land degradation which is estimated to cost $67 bn a year in America
For years, the amount of sargasso algae present in Caribbean and US waters and beaches has been increasing. And it's no longer relegated to the months when the water is warmer.

Florida, behind the invasion of seaweed two actions of man on land

,
The coasts of the US state and other Caribbean states are invaded by abnormal quantities of sargasso: it is estimated that the seaweed are almost 9,000 kilometers long and weigh 20,000 tons. However, the abuse of agricultural fertilizers and deforestation are at the basis of the phenomenon. A confirmation of the bond that unites the health of the soils with that of the oceans
