news from (and about) the trees

Pollution is changing the fungi that provide mineral nutrients to tree roots, which could explain malnutrition trends in Europe’s trees.

To get nutrients from the soil, trees host fungi, known as mycorrhizal fungi, in their roots. These fungi receive carbon from the tree in exchange for essential nutrients, like nitrogen, phosphorus and potassium, which they gather from the soil.

A huge, 10-year study of 13,000 soil samples across 20 European countries has revealed that many tree fungi communities are stressed by pollution, indicating that current pollution limits set by European countries may not be strict enough, that they may need to lower the amount of nitrogen and phosphorus levels allowed for soil amendments.
