TERRA DAILY – 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 from the Technical University Munich (TUM) 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.

In their study, which has been published in Science of the Total Environment (2015), scientists from the Technical University Munich (TUM) evaluated the crop yield statistics for EU countries compiled by the Food and Agriculture Organization of the United Nations (FAO) since the 1960s.
