Ecosystem services driven by the diversity of soil biota – understanding and management in agriculture
The project is part of the BiodivErsA-network SoilMan (Ecosystem services driven by the diversity of soil biota – understanding and management in agriculture). It is focused on ecology and economy of ecosystem services provided by soil biota.
The project SoilMan is determined to work on a deeper understanding of the interrelationship between farm based soil management practices and soil biodiversity in view of improving soil health and soil fertility. It will provide knowledge on how soil biodiversity in turn feeds back into soil functions and ecosystem services as factors for agricultural productivity and sustainability. It is recognized that soil biodiversity and biota interactions are pivotal for driving soil functions in agricultural systems supporting and regulating ecosystem services directed to agricultural production.
Via a systematic ecological, economic and political valuation of soil biodiversity in European agricultural systems, soil biota will be placed into a socio-ecological context. In order to better understand how farm-based soil management systems influence soil biodiversity and the sustainable provision of ecosystem goods and services, SoilMan will quantify soil ecosystem functions and multiple ecosystem services based on biodiversity parameters. A large number of state-of-the-art methods and tools in qualitative and quantitative soil ecosystem analysis as well as systematic economic and societal valuation of the services provided by soil biodiversity will be applied. The aim is to derive recommendations for the agriculture sector on sustainable soil management practices making best use of soil biota.
The Thünen Institute of Biodiversity conducts field and lab-investigations to assess the impact of soil management practices on the provision of ecosystem services by soil organisms within different biogeographical regions. The scientific work focuses on the repression on economically important fungal plant pathogens and their toxic secondary metabolites (mycotoxins) by soil fauna (earthworms and collembolans).
The Thünen Institute of Market Analysis is responsible for the socio-economic valuation of services provided by soil organisms as well as for the cross-national comparison and policy issues. In order to value the most important goods and services soil biodiversity can provide for farmers and the society as whole and to assess the impact of policy on its provision a modelling approach will be applied. The farm-based model PoMoSoB will be used for the study countries Germany, France, Spain, Sweden and Romania covering five major European biogeographical regions. In addition, the impact of policies on the provision of goods and services that soil biodiversity can provide will be assessed for the European Union including effects on agricultural production and possible impacts on agricultural trade by using selected market models, such as MAGNET or AGMEMOD. It is also foreseen to compare specific regional results – generated in field experiments and through stakeholder meetings – and to link them with the European policies debate in such a way that the results of SoilMan can be useful for policy and decision makers. Policy briefs and stakeholder recommendations of high impact for soil biodiversity will promote the use and application of SoilMan results in policy and practice.
