Soil Carbon
To cut emissions from cattle ranching, beef up the soil, study says
Flying this November into a remote region of the Orinoquía savanna in Vichada, Colombia, environmental biologist Jacobo Arango could spot the Hacienda San José cattle ranch that his team was using as an open-air laboratory. From the sky, he could see the farm’s greener hue of grass standing out against neighboring pastures. There, he and […]
Mycorrhizal fungi, nature’s ‘wood wide web,’ get a $3m conservation boost
Beneath our feet, a vast network of fungus spreads like a web. Mycorrhizal fungi connect the roots of plants to the surrounding soil, facilitating the exchange of water and nutrients for sugars from the sun and playing a vital role in the health of terrestrial ecosystems. Now, this “wood wide web” is getting a conservation […]
Study: Regenerative farming boosts soil health, yielding more nutritious crops
Plants build themselves from sunlight, water, and soil. And, as it turns out, what crops “eat” can influence the nutrients on our own plates. A recent study, published in the journal PeerJ, compared the nutritional content of food crops grown using conventional versus regenerative farming practices — those that build the soil by using cover […]
Trees and soil at the forest’s edge store more carbon than we thought, studies reveal
Trees and soils keep a lot of carbon trapped in the forest, pulling it from the atmosphere, where it can do more harm than good. In fact, roughly 30% of the carbon generated from fossil fuel burning is captured by forests. “That’s CO2 that’s not in the atmosphere,” said Boston University biogeochemist and ecologist Lucy […]
As its topsoil washes away, the Corn Belt is losing yields — and carbon
Chances are, if you live in North America, you’ve eaten corn from the Corn Belt, a region in the United States Midwest that produces 75% of U.S. corn. Scientists have found that around 35% of the region has lost its most fertile A-horizon soil, more commonly known as topsoil, since European colonization in the 1800s, […]
The complete guide to restoring your soil: Q&A with soil expert Dale Strickler
Son of a sharecropper and lifetime farmer, Dale Strickler has lived his life by the soil. Strickler grew up in an impoverished area near the Ozarks in the U.S. Midwest, where he says he watched as the crops on his family farm died from drought and as the topsoil washed away from tilled fields. “If […]
When it comes to carbon capture, tree invasions can do more harm than good
Trees are a logical solution to climate change, but allowing or encouraging trees to spread into areas where they don’t typically grow, such as tundra and grasslands, can actually do more harm than good. A newly published review paper in the journal Frontiers in Ecology and the Environment asks the question: “Should tree invasions be […]
