2021-01-21ZeitschriftenartikelA model ensemble approach to determine the humus building efficiency of organic amendments in incubation experiments Gasser, Anton A.; Diel, Julius; Nielsen, Kerstin; Mewes, Paul; Engels, Christof; Franko, Uwe; Mewes, PaulOrganic amendments are important to sustain soil organic matter (SOM) and soil functions in agricultural soils. Information about the contribution of organic amendments to SOM can be derived from incubation experiments. ...

2020-07-30ZeitschriftenartikelMonitoring N : P Ratio and Cd, Cu, Pb, and Zn Contents in Different Types of Anaerobic Digestates Roß, Christina-Luise; Nielsen, Kerstin; Krieger, Jorita; Hoffmann, Marieke; Sensel-Gunke, Karen; Ellmer, Frank; Kautz, TimoDepending on the quality of the input substrates, process parameters, and postfermentation treatments, digestates may contain a broad spectrum of potentially toxic elements. We suspected that these contents may vary on a ...

2023-01-05ZeitschriftenartikelSimulating the soil phosphorus dynamics of four long‐term field experiments with a novel phosphorus model Gasser, S. Anton A.; Nielsen, Kerstin; Eichler-Löbermann, Bettina; Armbruster, Martin; Merbach, Ines; Franko, UwePhosphorus is a nonrenewable resource, which is required for crop growth and to maintain high yields. The soil P cycle is very complex, and new model approaches can lead to a better understanding of those processes and ...

2020-06-24ZeitschriftenartikelThe Chemical Composition of Biogas Digestates Determines Their Effect on Soil Microbial Activity Nielsen, Kerstin; Roß, Christina-Luise; Hoffmann, Marieke; Muskolus, Andreas; Ellmer, Frank; Kautz, TimoDigestates are commonly used as organic inputs in agriculture. This study aimed to answer four questions: (1) What are the immediate and longer-term impacts of digestates on soil microbial activity?; (2) How much of the ...

2022-05-07ZeitschriftenartikelTransfer of carbon incubation parameters to model the SOC and SON dynamics of a field trial with energy crops applying digestates as organic fertilizers Gasser, S. Anton A.; Nielsen, Kerstin; Franko, UweThe fertilization with organic amendments and digestates from biogas plants is increasingly used to increase carbon stock and to improve the soil quality, but little is still known about their long-term effects. A common ...
