Soil Quality & Functions

Soils provide essential ecosystem services for human well-being and ecosystem functioning, e.g. food, water and greenhouse gas regulation including carbon storage, and biodiversity conservation. Most of the soil’s ecosystem functions are closely related to soil organic matter (SOM) and its beneficial impacts, such as the improvement of soil structure and fertility of agricultural soils. They contribute to plant productivity and health, water holding and retention capacity, and resistance against drought and extreme weather events. An intact soil is of particular importance for organic farming systems because crop production in such systems relies on the nutrient transformation processes catalysed by soil biota.

We explore the following questions:

  • How do farming systems imping on soil quality in the long term?
  • What are the effects of new technologies such as genetically modified crops, bio-control organisms and soil improvers such as biochar on essential soil functions?
