Cover Crops May Be Used to Mitigate and Adapt to Climate Change

Cover crops long have been touted for their ability to reduce erosion, fix atmospheric nitrogen, reduce nitrogen leaching and improve soil health, but they also may play an important role in mitigating the effects of climate change on agriculture, according to a Penn State researcher.

Widely Accepted Vision for Agriculture May Be Inaccurate, Misleading

Food production must double by 2050 to feed the world’s growing population.’ This truism has been repeated so often in recent years that it has become widely accepted among academics, policymakers and farmers, but now researchers are challenging this assertion and suggesting a new vision for the future of agriculture. New research suggests that production likely will need to increase between 25 percent and 70 percent to meet 2050 food demand.

Harvests in US to Suffer From Climate Change

To better assess how climate change caused by human greenhouse gas emissions will likely impact wheat, maize and soybean, an international team of scientists now ran an unprecedentedly comprehensive set of computer simulations of US crop yields.

Mississippi River Could Leave Farmland Stranded

If the Mississippi River continues to go unchecked, the farmland on Dogtooth Bend peninsula may be only accessible by boat. According to a University of Illinois study, each successive flood carves a deeper channel across the narrow neck of the peninsula.

Soil Could Become a Significant Source of Carbon Dioxide

If people continue using and changing the land over the next century in the same way they currently do, soils will become a net source of atmospheric carbon dioxide, experts have warned. Promotion of land use changes and management that contribute to soil carbon sequestration remains essential in an integrated strategy to protect soil functions and mitigate climate change.

Life on the Edge of a Habitat Is Dangerous

Intensive farming, sprawling towns, a dense road network — the modern world leaves less and less space for animals and plants. They are forced back into shrinking refuges, which are ever further apart. According to this study, animals living on the edge of their range suffer more from the fragmentation of their habitat than their fellows in the center.

Bacteria in branches naturally fertilize trees

Science has only recently delved into the importance of the microbiome of plants. “Having access to the key microbial strains that help wild plants thrive on just rocks and sand will be crucial for moving agriculture, bioenergy and forestry away from a dependence on chemical fertilizers and towards a more natural way of boosting plant productivity,” Doty said.
