Canada’s grasslands are getting hotter and drier

,
A study by the University of Alberta has described for the first time the changes that have occurred in the country's grasslands over the past 120 years and the consequences for agriculture

“Soil care is crucial to ensure food security”, WEF says

,
To meet growing food demand while capturing proper volumes of greenhouse gases, soil health must be a priority, says the World Economic Forum. Precision agriculture is essential
Over the past 12,000 years, 2.7 billion tons of phosphorus have reportedly accumulated in lake sediments around the world.

The phosphorus problem started thousands of years ago

,
A Swiss study found that humans began altering the phosphorus cycle many millennia ago. Before industrialization and the spread of fertilizers accelerated the process

For sustainable carbon cycles we need to focus on nature-based solutions

,
Second edition of the General States of the Soil at Ecomondo in Rimini. Dozens of experts attended to discuss the best strategies capable of bringing organic carbon back into degraded soils and reducing CO2 in the atmosphere

New insights into the relationship between viruses and soil bacteria

,
According to UC Davis researchers, soil viruses appear to act "like lawnmowers, culling older cells and giving space for new growth"
The term "permafrost" refers to the type of perennially frozen (but not necessarily ice-covered) soil found in some cold regions. Photo: NPS Climate Change Response CC BY 2.0 DEED https://www.flickr.com/photos/npsclimatechange/27759123542Photo: NPS Climate Change Response CC BY 2.0 DEED

Superficial permafrost could (almost) disappear by 2100

,
By the end of the century, near-surface permafrost may exist only in the highlands of eastern Siberia, the High Arctic and northern Greenland. As was the case 3 million years ago
The influence exerted on the population composition of microorganisms comes from the ability of earthworms to influence soil structure, pH, nutrient availability and organic matter. Photo: benketaro Attribution 2.0 Generic (CC BY 2.0)benketaro Attribution 2.0 Generic (CC BY 2.0)

Earthworms are changing Canadian forests

Soil microbes will release 40 percent more CO2 by 2100

,
Climate change is increasing the respiration of soil microbes and related CO2 emissions. A phenomenon, says a Swiss study, set to accelerate between now and the end of the century
