In the context of sustainable agriculture, a deeper knowledge of the effects of soil management on soil annelids is needed, as they play an important role in many soil processes. In a laboratory mesocosm experiment, we compared the simulated effect of ploughing by inverting the top soil (crop residues at 15 cm depth) to a non-inversion treatment (c...
Article
The concept of values has been extensively used as a proxy to investigate relationships between human-beings and their environment. Using a pragmatic epistemology, we investigated valuation processes at stake when farmers choose their management practices, focusing on soil biota valuations. We sought to determine to what extant values are situation...

The introduction of temporary grassland into an annual crop rotation is recognized to improve soil ecosystem services, and resulting legacies can be beneficial for the following crops. In this context, the aim of the present study was to evaluate legacy effects of introducing temporary grassland into an annual crop rotation on five ecosystem servic...
Conference Paper
Traditionally, soil quality has been assessed through physical, chemical and biological properties without paying attention to soil biota and the different associated ecosystem services provided (Tyler, 2019). To fill that gap, the european BiodivERsA "SoilMan" project (Ecosystem services driven by the diversity of soil biota - understanding and ma...
Article
Agriculture benefits from soil functions, whereof many depend on soil biota, but some management practices can threaten soil organisms. We inventoried values that European farmers associate to soils and soil biota into their soil management decisions. We used Dewey’s pragmatic epistemology, stating that values can be observed through active behavio...

Tillage is known for its adverse effects on soil biota, at least in arable agroecosystems. However, in vineyards effects might differ as tillage is often performed during dry periods or only in every other inter-row allowing species to re-colonise disturbed areas. We examined the response of earthworms (lumbricids), springtails (collembola) and lit...
Article
Climate change will affect the survival of plant pathogens and the decomposition of crop residues on temperate arable soils. Information on the survival of fungal plant pathogens is important for assessing the subsequent infection risk of susceptible agricultural crops. Therefore, a soil warming experiment was performed to examine the effects of ri...
Conference Paper
Agroforest systems are highly discussed as new and innovative land use systems for arable land in temperate regions. They are recommended due to their beneficial impact on several ecosystem functions and for the general diversification of the cultured landscapes. Tree rows, known as alley cropping systems, are one of the most frequent applications....
Conference Paper
Pastures with low grazing pressure are often characterized by a sward mosaic of short, frequently grazed and tall, rarely grazed patches. These two patch types differ in the quantity of litter returned to the system, but may also produce different litter quality and provide different conditions for decomposition. We collected litter from short and...

To monitor the effects of liming on forest ecosystems, experimental plots were installed in forests in mid-western Germany. In addition to soil chemical indices, earthworm communities were investigated on these plots about 15 years after first lime applications took place. As a “natural reference”, communities were compared to earthworm records tha...
Article
Chisel plough or no-till practises are clearly attributed to sustainable farming for the support of soil organisms and soil biological functioning. However, in organic farming these techniques are only applied to a very small extent since there is a need for cultivation to control weeds. In organic farming it is important to develop and establish l...
