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
Present in several products, including fire extinguisher foam, fluoride-based pollutants, so-called PFAS or per- and polyfluoroalkyl substances, are extremely difficult to dispose of. Photo: Brett Clashman, U.S. Air Force Public domainPhoto: Brett Clashman, U.S. Air Force Public domain

Ball milling cleans soil of persistent fluoride

,
Researchers in New Zealand are testing a solution against fluoride pollution. The technique has made it possible to degrade per- and polyfluoroalkyl substances (PFAS) at the molecular level with 99.9 percent efficacy

The solution for the 2030 climate goals lies in agricultural soils

,
Jacqueline McGlade, former EEA executive director and co-founder of Downforce say some easy management strategies in agricultural soils can increase the amount of carbon stock by more than 30 bn metric tons

Pesticides do not escape nanosensors. From Sweden a low-cost solution

,
Inexpensive nanosensors can detect pesticides in orange juice, explain researchers at Karolinska Institutet in Stockholm. Experimentation has shown their efficacy and the possibility of massive production

Climate change anticipates bee awakening putting crops at risk

,
British study: rising spring temperatures make bees wake up too early. Synchronization between insects and plants is lost and crops are affected. 1°C warming corresponds to an average anticipation of 6.5 days

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

Extensive farming increases flooding in South America

,
According to an Anglo-Argentine study, the spread of large-scale agriculture over the last four decades has favoured the rise of water tables in the plains of South America. Substitution of native vegetation has been crucial factor
