Abstract
We steered the soil microbiome via applications of organic residues (mix of cover crop residues, sewage sludge + compost, and digestate + compost) to enhance multiple ecosystem services in line with climate-smart agriculture. Our result highlights the potential to reduce greenhouse gases (GHG) emissions from agricultural soils by the application of specific organic amendments (especially digestate + compost). Unexpectedly, also the addition of mineral fertilizer in our mesocosms led to similar combined GHG emissions than one of the specific organic amendments. However, the application of organic amendments has the potential to increase soil C, which is not the case when using mineral fertilizer. While GHG emissions from cover crop residues were significantly higher compared to mineral fertilizer and the other organic amendments, crop growth was promoted. Furthermore, all organic amendments induced a shift in the diversity and abundances of key microbial groups. We show that organic amendments have the potential to not only lower GHG emissions by modifying the microbial community abundance and composition, but also favour crop growth-promoting microorganisms. This modulation of the microbial community by organic amendments bears the potential to turn soils into more climate-smart soils in comparison to the more conventional use of mineral fertilizers.

N1 - Funding Information: We thank Dr. Susanne Brenzinger for helping with the creation of Fig. 6. We are grateful to Iris Chardon, Agata Pijl, and Hans Zweers for their excellent technical assistance. We thank Jeroen van Lanen (Van Iersel Compost, The Netherlands) for providing us with the compost, Phillipe Packbier (Joordens company, The Netherlands) for providing us with the CC residues, Rob Verheijn (Vallei Veluwe, The Netherlands) for providing us with the sewage sludge, and Rommie van der Weide and Sjaak van Brugge (ACRRES, The Netherlands) for providing us with digestate. Thankfully, Dr. Emilia Hannula provided us a database of fungal pathogens. Sander van Acqouij and Anna-Reetta Salonen for experimental help with wet sieving to determine aggregate fractions. We thank Prof. Dr. Rob van Spanning for fruitful discussion about our data. This publication is publication number 7285 of the Netherlands Institute of Ecology (NIOO-KNAW). Funding Information: KB is financially supported by the grant from the German DFG BR 5535/1–1 and by a grant from the Dutch Research Council (NOW) number 870.15.073.
