Agriculture contributes to climate change. But changes to how farms manage soil might help remove carbon and other greenhouse gases from the air.
This win-win technology means future farmers may produce both food and electricity.
Agrivoltaics merges agriculture with photovoltaic panels, which generate electricity from sunlight. The combo produces clean energy and edible crops.
Plants are already the best carbon catchers on Earth. New research could make them even better.
But how useful this is depends on whether cows eat the red algae, a type of seaweed — or it gets added to their wastes after they’re pooped out.
Microplastics in the soil hinder plant growth. But two finalists at Regeneron ISEF found that fungi and farm waste can reduce the harm.
At Regeneron ISEF, three teens debuted an infrared system to detect honeybees carrying mites. It can show beekeepers when a colony needs to be treated.
Six young researchers took home the top awards, each valued at a minimum of $50,000. Hundreds more shared nearly $9 million in prizes at international event.
Modern Amazonians make nutrient-rich soil from ash, food scraps and burns. The soil strongly resembles ancient “dark earth” found in the region.
