Is Climate Change a threat to soil quality.... humus depletion induced by climate change.

The yields of many important crops in Europe have been stagnating since the 1990s. As a result, the input of organic matter into the soil -- the crucial source for humus formation -- is decreasing. Scientists suspect that the humus stocks of arable soils are declining due to the influence of climate change. Humus, however, is a key factor for soil functionality, which is why this development poses a threat to agricultural production -- and, moreover, in a worldwide context.

Soil Scientists turn oily soil into fertile ground.

Scientists are cleaning soil contaminated by oil spills in a way that saves energy and reclaims the soil's fertility, using a process known as pyrolysis, which involves heating contaminated soils in the absence of oxygen.
