Cheers and Congratulations to Yujia Liu - PhD thesis submitted - she worked on a better understanding of denitrification processes at hot-spots in Danish croplands - way to go 💪 @ucph.bsky.social

starting every new month with a group brunch, everyone brings something - loads of delicacies and good coffee 🤩@tuberlin.bsky.social

summer seems endless in Berlin - the view from our lab - pure magic these days 😉

more photo backup...with some favorite sport shots ;)

while adding another backup for all my photos, coming across some polar logistics shots... makes me really looking forward to the next field season up North :D #Antarctica #Arctic #fieldwork #logistics

final project report just submitted, new project proposal ready for submission - sometimes science is just a hamster wheel - let’s call it a week 😓

early birthday present to my group …and me ☺️ From today on, if you visit us, we‘ll have espresso and Co for you, maybe even the professor will do the barista 😉

it’s a cloudy stormy autumn day in Berlin, but at least there’s sunny agriculture socks #urbanfarming

Glienicker Brücke, the old „spy bridge“ between former Eastern and Western Germany always offers a magic view on my daily commute #cycletowork

Extended deadline! Submissions welcomed until 1st December to the npj biodiversity collection: Impacts of Global Change on Polar Terrestrial Biodiversity 🐻‍❄️🐧 Edited by: @annebeejay.bsky.social, Daly Noll Vergara, Luis Pertierra and me www.nature.com/collections/...

Ich hoffe, dass es hilft Menschen für die wunderbare Welt des Bodens zu begeistern. Aber auch für die Wissenschaft, die hinter diesen Erkenntnissen steht. Hier der Link zum Buch: www.ullstein.de/werke/mutter...

Finished the poster for our just funded project: "CINCA - Climate change Impacts on Nutrient and Carbon Allocation in soils of maritime Antarctica" for the @dfg.de priority program 1158 #Antarctic Research workshop in Bremerhaven next weekend - we are all excited to continue our work in #Antarctica

magic scenes that you completely miss when commuting by car or train #cycletowork #Jungfernsee #Potsdam

summer was very productive in our soil science 'art studio' 🥰 - lacquer profiles from the @tuberlin.bsky.social campus in the making #soilart #urbansoil #artefacts

First day back in the lab after the summer feels like birthday presents arrived early 🥳 We now have a second new BET (specific surface area), operated together with @umweltbundesamt.bsky.social and our "IRMS project" from Nuuk, Greenland - both are now waiting for the gasses to be connected 😉

This meta-analysis finds that planting nitrogen-fixing species increases soil carbon compared with non-nitrogen-fixing species, potentially offering a nature-based solution to mitigate climate change for forestation, agriculture and land regeneration 🧪🌳 www.nature.com/articles/s41...

I‘ve never been in Africa so far, but thanks to my lab head Anne Wagner I now have a little piece of Africa in my office 🤩 …thanks to our Namibia project supported by seed funding of @tuberlin.bsky.social

Prepping for the farewell of Ingrid Koegel-Knabner #SOMQueen today, and somehow I feel a bit older too going through all the photos 😉

We are seeking a new director for our institute: Director (f/m/d) at the Institute of Bio- and Geosciences – Agrosphere (IBG-3) at Forschungszentrum Jülich @fz-juelich.de with professorship (W3) in Terrestrial Systems Analysis at the @unibonn.bsky.social University of Bonn Please share this

The good, the bad and the ugly" - really nice talk by @markussteffen.bsky.social about carbon farming and its pitfalls from a Swiss perspective today at #DBG25

Doing my last edits on my keynote for today - bringing some #soilscience into the physics realm #SIMSEurope #SoilBiogeochemistry #NanoSIMS @alixvidal.bsky.social @tuberlin.bsky.social @ucph.bsky.social

What a summer! I‘m very happy about yesterday’s defense of now Dr. Vera Baumert - it was great working with her on how #rhizodeposition affects #subsoil #carbonsequestration - check her work: www.sciencedirect.com/science/arti... and here: www.frontiersin.org/journals/env... #SOC #SOM #Rhizosphere

Earlier this week @kristinawitzgall.bsky.social successfully defended her PhD thesis 👏 What a great pleasure to work together with her from her MSc to PhD. And as a dad of a little girl, great to have such female role models! Check her latest paper: onlinelibrary.wiley.com/doi/full/10....

Always a nice feeling to send the signed compliance form to @dfg.de after you‘ve submitted a new research proposal - and now, fingers crossed 🤞 …now off to the next proposal 😉 @tuberlin.bsky.social

And I published a preprint🥳 We combined O2-sensitive optodes, root imaging, and N2O microsensors to identify and characterize N2O hotspots in the rhizosphere of maize🌽 www.biorxiv.org/content/10.1... Great collaboration with many cool people (that are not on bluesky) including @cwmsoils.bsky.social

Amazing what you stumble across in the storage room of my lab, a really nice geological collections of the geoscience institute. Who doesn’t love fish fossils? 🤩

🚨 New paper alert! 🚨 Soil, rhizosheath formation, and maize 🌱🌽. Congrats to Franziska 🥳 for a fantastic piece of her PhD work! Rewarding to see results from this challenging field experiment with rainout shelters 😅 Check it out ➡️ link.springer.com/article/10.1...

Word!

The German academic system offers a lot, but it also has considerable flaws! We all have to push for a system that ensures no one is bullied, and especially early career scientists are supported in a fair and collaborative manner! #academicchatter #scientificmisconduct www.nature.com/articles/d41...

My close by playground for the nature and soil nerd in me - former military training ground, now large #rewilding area close to #Berlin - where remains of blown up bunkers, endless sand pits and European bison meet #DoebritzerHeide #gravelbike #SielmannStiftung

I used the loooong flight home from #EGU25 to finalize and push a new release of the freely-available Soil Respiration Database github.com/bpbond/srdb/ #openscience

That’s the kitchen I like 😁 #soilorganicmatter #SOM #soilcarbon

#EGU25 is in the books, a week full of great science and meeting many colleagues - and nice to see clear statements and actions for more diversity! See you next year at @egu.eu

See you at #EGU25 next week - there are plenty of presentations from our joint projects on the menu in Vienna #Rewilding #Rhizosphere #SoilOrganicCarbon #Denitrification #Phosphorus #SoilScience @egu.eu

Check out this cool homepage, where you can even create your own nerdy stickers 🤓: saveland.art/en/

Happy Easter - with plenty of colored eggs. A Sorbian (Slavic minority living in Eastern Germany) custom to use small drops of hot wax applied with needles, cut bird feathers etc. and repeated dyeing to create small fragile pieces of art - these ones were made by my sister 😁 #eastereggs

Todays challenge: working on a proposal sitting in the kids wagon with an action cartoon on 🤣 #českédráhy

Let’s call it a day…off to a long Easter weekend @tuberlin.bsky.social

Spring in full swing around our institute, and finally my office furniture arrived - ready for creative meetings up at the 10th floor - so come along, summers are nice in Berlin 😁

🌍 Biologische Bodenkrusten halten die Böden der Erde stabil, sind aber vom #Klimawandel bedroht. Eine Studie von @cwmsoils.bsky.social & @kristinawitzgall.bsky.social zeigt nun, dass geschädigte Böden langfristig zu einer Bedrohung für globale Kohlenstoff- und Stickstoffkreisläufe werden können.

Yes, we have to get much better in science to communicate our work to the public and decision makers! And we should raise our voices much stronger in decision making processes. Interesting read in @nature.com www.nature.com/articles/d41...
