How do we decide what grows where? 🌱🧪⚒️ Our new paper analyzes 100 years of land-use history across 3,104 sites in Germany and finds that hydrological properties shape our agricultural landscapes. doi.org/10.1002/jpln... @cwmsoils.bsky.social @thuenen.de #Hydrology #LandUse #Sustainability #Soil

Hydrological Conditions Outweigh Soil Texture, Temperature, and Terrain in German Agricultural Land Use

Background The availability of fertile land suitable for agriculture is limited. In the European Union, political demand for self-sufficiency in staple food production currently competes with increa...

🧪📢 New research! “Site-Specific Drivers of Land-Use Change Effects on Organic Carbon in German Agriculture and Forest Soils”. doi.org/10.1111/gcb.... We reveal that ~30 % of land-use change induced SOC change occurs in the subsoil, with soil type driving most change. #soil #soilscience #climate

Site‐Specific Drivers of Land‐Use Change Effects on Organic Carbon in German Agriculture and Forest Soils

Land-use change—for example, turning cropland into forest—alters soil organic carbon (SOC) storage to different degrees depending on soil type. Data from the German national agricultural and forest s...

Our article on the importance of accurate use of language surrounding the concept of carbon sequestration was one of @globalchangebio.bsky.social top 10 most cited! #TopCitedArticle 🧪 Check it out here: doi.org/10.1111/gcb....

Carbon sequestration in soils and climate change mitigation—Definitions and pitfalls

Sequestration of carbon in soils can lead to climate change mitigation or even negative emissions. However, not all measures enhancing soil C result in such C uptake from the atmosphere or negative e...

Lots of new people joining Bluesky, and lots of great starter packs floating around, so here’s another idea: if you work at the intersection of food/agriculture, nature, and climate, introduce yourself and what you do below so folks can keep connecting. Who’s here now?

🧪After presenting this research at conferences for the past two years, I'm very pleased to finally cross the finish line. Kudos to my co-authors for their insight and endurance. Read about the centennial legacy of land-use change on soil organic carbon here: doi.org/10.1111/gcb....

📣It's time to sign up for Skype a Scientist 2024 We match scientists w/classrooms, scout troops, libraries, & more for conversations about science! We have a growing list of scientist volunteers. We'll match you for FREE virtual Q&As! Sign up here: skypeascientist.com/sign-up.html

a brief how-to image that says "Talk to your scientist! Pick a category of science your group would like to talk about (e.g. marine biology, chemistry, astronomy) Get a match via email Discuss your class's needs with your scientist, and pick a time to chat". It's light blue and dark blue and has a little test tube, DNA strand, and microscope and our logo

Gotta respect a clothing company that goes out of its way to reduce the amount of clothes you buy in favour of the environment.

Screenshot from the ASKET website showing that they are closed and not selling clothes during Black Friday in protest of the mass consumption promoted by such sales.

Measures to build up soil C in agriculture don't always lead to C sequestration, but may reduce soil C losses. The correct use of terms prevents exaggerated expectations towards climate mitigation. Find definitions a new EJPSoil paper from colleagues at the Thünen Institute: 🧪⚒️ #soilscience

Hi bluesky! My name's Dave, I study soil carbon in agricultural systems. I'm currently looking at the historical effects of land use on soil organic carbon. But also, I love reading and geeking out to anything tech.
