Climate change to disrupt soil nutrients in drylands

The increased aridity expected this century as a result of change may disrupt the balance of key soil nutrients with a knock-on effect on soil fertility threatening livelihoods of more than two billion people, a study finds.

The drop in nitrogen and carbon concentrations that occurs as soils become dryer could have serious effects on ecosystem services such as food, carbon storage and biodiversity, according to the Nature paper published today.
