Reducing stand density significantly enhances #TreeSpeciesDiversity, which in turn promotes #SoilOrganicCarbon accumulation by influencing microbial carbon fixation and degradation potential.

New research in Global Change Biology highlights the centennial legacy of land-use on German agricultural soils.

​It can take 180 years for soil organic carbon to stabilize after land-use change—meaning today’s carbon stocks are still shaped by history from the 1800s.

🔄 After grazing exclusion, #SoilOrganicCarbon (SOC) and #TotalNitrogen (TN) quickly recovered with their storage peaking at different exclusion durations. Differences in SOC and TN storage were primarily driven by #Roottraits at the community-level.

🔄 How #SoilOrganicCarbon (SOC) storage and its stabilizing mechanism vary along #AltitudinalGradients ❓

Results:
Altitudes ⬆️, SOC contents →
⭐ bulk soils and #HeavyFractions ⬆️;
⭐ #SoilAggregates ➖;
➡️➡️ The increase in Fe/Al oxides might be the reason.

#SoilOrganicCarbon (organic matter / plant and animal residues at various stages of decomposition) is one of the key indicators of hashtag#soilhealth / soil ecosystem services. But how do you measure and report SOC? We advocate that SOC density [kg/m3] is the central variable to monitor SOC dynamics. It is derived by measuring SOC content and Bulk density (separately) and then by a simple formula:

SOC [kg/m3] = SOC [dg/kg]/100 * BD [kg/m3] * (1-CF)

*CF is the coarse fragments fraction (0-1).

Shiwen Ding et al. found that different #LivestockSpecies changed the relationships between #PlantFunctionalDiversity and #SoilOrganicCarbon in the #MeadowSteppe, illuminated the considerable impact of livestock species on the intricate mechanisms of #SoilCarbon sequestration.

On NYE, as I look back at 2024, I want to share three Senate reports, of which I am quite proud. The first is Critical Ground, the major two-year study carried out by the Standing Senate Committee on Agriculture and Forestry - a comprehensive look at soil health in Canada & a call to action to protect our farm soil & native grasslands, not just for food production, but for climate change mitigation. https://sencanada.ca/en/info-page/parl-44-1/agfo-critical-ground/ #SenateofCanada #soil #soilhealth #climatechange #soilorganiccarbon

🌱 Registrations for the Soil Health Now! Conference are now open! 🌱 https://2025.ai4soilhealth.eu/#submit

🌲From April 8-10, 2025, we will be hosting the Soil Health Now conference, alongside workshops and discussion forums at the Wageningen International Conference Center (WICC). 🌿 The event will feature 12+ pan-European "Mission Soil" projects and 11+ distinguished keynote speakers.

I am too “old” now, but did participate in 2021 at the #EUSO #EUSoilObservatory Young #Soil Researcher Forum, and it was a lot of fun 👇

Spatial co-variation matters when upscaling environmental samples like soil organic carbon stocks. Geostatistics is under-utilized in most regional estimats. Strong spatial autocorrelation preserves uncertainty in upscaled estimates. By not taking this into account, may estimates report uncertainties that are too small. Properly taking this into account requires large sample sizes. Wadoux and Heuvelink 2023 https://doi.org/10.1111/2041-210X.14106

To a bystander it looks like brutal treatement yet it's only SOP in science. And the reply is a fun bit of cut-and-thrust concluding with a polite (barbed?) thank-you:

"...we thank Kästner et al. (2024) for raising questions to highlight the most important statements in our review..."

But more importantly, at this juncture it seems we'd best figure this out once and for all, global carbon sink/source/flux/budget being all-inclusive?

One of those papers where I'm a little ashamed at how long it took me to find/read.
