Litter manipulation experiment Grinderwald - Density fractionation data from soil core samples

Patrick Liebmann, Patrick Wordell-Dietrich, Karsten Kalbitz, Robert Mikutta, Fabian Kalks, Axel Don, Susanne K. Woche & Georg Guggenberger
We conducted a litter manipulation experiment with 13C enriched beech litter at the Grinderwald research site, 40 km north of Hannover, Germany. The study site contains a more than 100 years old beech forest on a Dystric Cambisol. At 2 time points (11.2016, 05.2018), we took soil cores down to 180 cm soil depth and divided them in 15 depth increments. We conducted density fractionation from chosen depth increments (0-50 cm, 100-140 cm soil depth)...

ARD Splitroot

Annmarie-Deetja Rohr, Jannika Staudt, Katharina Cziborra, Annabel Fritz & Michaela Schmitz
Apple replant disease (ARD) is a threat to apple fruit and tree production worldwide caused by shifts in the soil microbiome. Chemical and physical measures of soil disinfection are the most employed countermeasures but inter-row plantings demonstrate that ARD is widely immobile in the soil, which causes the plant to face ARD affected and healthy soil simultaneously in the field. We simulated this situation in a split-root approach in two experiments using rhizoboxes, soil from...

Survey of farmers on their perception of soil compaction and application of soil conservation measures

Ledermueller Sandra & Fick Johanna
While the scientific aspects of soil compaction are studied since decades, there is hardly insight on knowledge and perception of this topic among farmers. Furthermore, there is hardly information on the dissemination of soil conservation measures to avoid soil compaction. For this reason, we conducted a German-wide online survey among farmers on this topic in autumn/winter 2017/2018. A further aim was to collect information on the dissemination of new technologies (apps) and to identify possible...

Earthworm data 2018 in agroforestry and monoculture - Bonares-SIGNAL-Projekt

Martin Potthoff & Jan Rattay
Earthworm biomass was determined based on earthworm hand-sorting from a 0.25 x 0.25 x 0.25 m soil block in summer 2018. All earthworms were collected from the soil, stored on filterpaper for 24h. The earthworms were than weighted after the guts were empty. Earthworm biomass is given as the sum of all earthworms from one soil block related to a surface area of 1m2.
