Carbon feedback from forest soils to accelerate global warming

After 26 years, the world's longest-running experiment to discover how warming temperatures affect forest soils has revealed a surprising, cyclical response: Soil warming stimulates periods of abundant carbon release from the soil to the atmosphere alternating with periods of no detectable loss in soil carbon stores. The study indicates that in a warming world, a self-reinforcing and perhaps uncontrollable carbon feedback will occur between forest soils and the climate system, accelerating global warming.

Win-win strategies for climate and food security

Efforts to reduce greenhouse gas emissions from the agriculture and forestry sectors could lead to increased food prices -- but new research identifies strategies that could help mitigate climate change while avoiding steep hikes in food prices.

Modeling the impact of green eggs and hens

Poultry given vegan organic chicken feed can help to produce eggs with a smaller environmental footprint than those fed non-organic feeds that contain animal by-products, new research shows.

Spectroscopy: Simple solution for soil sample

Traditional ways of analyzing soil texture are slow. Researchers have shown a new, high-tech method that is fast, cost-effective, and portable. This technique could make it much easier to understand the soil texture of a particular area -- or even large areas across the globe.

The outsized role of soil microbes

Three scientists have proposed a new approach to better understand the role of soil organic matter in long-term carbon storage and its response to changes in global climate and atmospheric chemistry.

Survival of soil organisms is a wake-up call for biosecurity

Tiny creatures in soil that attack plants have the ability to survive for at least three years stored in dry conditions, showed a recent study. Furthermore, they were found to still be able to invade plant roots. The research article provides new insights into the biosecurity threats posed by passenger travel and trade between countries and tests various methods for nematodes detection.
