Leaf nutrient balance helps explain earlier fall color in US forests
Researchers at Duke University have found a key factor that influences when leaves change color in US forests during the fall season. The study discovered that levels of certain nutrients in leaves play a role in determining when fall colors begin to appear. This has implications for predicting leaf drop and tracking carbon cycles.
Why it's good news: Who enjoy planning fall foliage excursions, as more accurate forecasts can help them make the most of their time outdoors.
