Root bacteria help reduce the environmental impact of rice cultivation

,
A Japanese study has identified some bacteria in rice roots that are responsible for nitrogen fixation and can spread in soil without fertilizers or pesticides. This helps the plant adapt and grow

Plant roots could store more carbon than previously expected at greater depths

,
An American study reveals the existence of a second layer of roots developed by several plant species—often overlooked—that enables additional carbon sequestration

Extreme heat waves are becoming longer and more frequent

,
A study on abnormal heat phenomena, involving researchers from the United States and Chile, reveals an acceleration of the trend on a global scale. Tropical regions are the most affected

A public database collects information on soil fungi

,
After years of study, a group of U.S. researchers has mapped the spore traits of 344 species of arbuscular mycorrhizal fungi. Gaining relevant information to assess their distribution and resilience to stresses
Drones can photograph the health of crops providing crucial information to farmers. Photo: Nikola Tomašić Pexels free to usePhoto: Nikola Tomašić Pexels free to use

Drones are the new allies of hemp farmers in the US

, ,
Processing of images captured by drones, a study from the University of Florida states, makes it possible to assess the health and growth status of plants by providing guidance on the optimal fertilizer dose
Peat soils in Ireland are more widespread than previously thought as they cover 30% of the land area compared with previously estimated 24%. Photo: SoilScience.info Attribution 2.0 Generic CC BY 2.0 DeedSoilScience.info Attribution 2.0 Generic CC BY 2.0 Deed

Ireland has mapped its peat soils (through AI and gamma rays)

, ,
By combining AI machine learning with radiometric data, researchers at the University of Galway managed to identify not previously detected peat soils
Grasslands are home to a wide variety of plant species and provide numerous ecosystem services, such as carbon sequestration, support for pollinators and grazing for livestock. But they are also some of thh most threatened ecosystems due to human activities, including land use change and intensive agricultural practices.

Study reveals how much nitrogen grasslands can tolerate

, ,
According to researchers, applying more than 80 kg of nitrogen per hectare in a year would make grasslands “functionally poor, highly unstable and vulnerable to extreme weather events”

How AI will ensure better prediction of erosion

,
L'Università dell’Illinois, ha testato un sistema di apprendimento automatico che combina diversi modelli predittivi dell'erosione. Con risultati migliori rispetto a quelli ottenuti dai singoli algoritmi
According to the authors, more than 50 percent of mangrove forests undergo significant changes due to El Niño and La Niña phenomena. Photo: Katia Schulz Attribution 2.0 Generic CC BY 2.0 DeedPhoto: Katia Schulz Attribution 2.0 Generic CC BY 2.0 Deed

Climate oscillations are a constant threat to mangroves

,
A study shows for the first time how temperature changes in the Pacific Ocean impact mangroves as they follow a specific pattern. In degraded areas, their ecosystem services are at risk
In 50 years, wheat, corn and barley yields (photo) are 10, 4 and 13 percent lower than they would be under normal circumstances. Photo Dag Endresen Attribution 2.0 Generic CC BY 2.0 DeedPhoto Dag Endresen Attribution 2.0 Generic CC BY 2.0 Deed

Climate change has reduced grain yields by up to 13 percent in 50 years

,
Warmer and dryer weather favors water stress thus impacting the productivity of wheat, corn and barley crops, a study from the Standford University has found. New investments and more accurate predictive models are needed for the future
