"Human activities, such as deforestation and the expansion of agricultural areas, have [caused] large amounts of carbon [to be] released into the atmosphere, contributing substantially to anthropogenic climate change.

A team led by LMU geographer Raphael Ganzenmüller has now calculated that human influence has reduced natural land carbon stocks by a total of 24%—which corresponds to 344 billion metric tons of carbon."

#SoilCarbon

Plants, like grass and food crops, love stable conditions. A farm I'm involved in is doing an experiment with hedgerows and the first graphs are in. Too early to brag, but the results look very much like: hell yeah, hedgerows FTW. This makes me very happy this morning :)

I will have to alert the researcher to #grafiekPolitie before they publish I see ;)

Australian companies and farmers experiment with using crushed basalt on farms instead of fertilisers - with promising results.

I wonder if I could find some crushed basalt for my depleted soil in inner- suburban Melbourne?

We are adding some 110TB of analysis-ready data to https://EcoDataCube.eu (all cloud-optimized as COGs or PMTiles). The upgraded system includes dynamic soil properties "Soil Health Data Cube" part of the @ai4soilhealth and @earthmonitororg projects, bimonthly time-series of biophysical indices (https://doi.org/10.5194/essd-17-741-2025), including the vegetation height annual (https://doi.org/10.21203/rs.3.rs-6521333/v1) and #soilcarbon density predictions (https://doi.org/10.21203/rs.3.rs-5128244/v2).

An Interesting NYT article on the possibilities of soil carbon storage in Australia using fungal spores. This will also help in building up the carbon nutrients in agricultural soils. But Australia's #SafeguardMechanism allows Fossil gas companies to offset Scope 1 & 2 emissions through buying carbon credits, which is highly problematic.

Curious about the spatial distribution of soil organic carbon across the United States? Of course you are! Wang etall 2024 https://agupubs.onlinelibrary.wiley.com/doi/10.1029/2023JG007702 used a combination clustering and random forest approach to upscale point estimates of soil carbon stocks. #SoilCarbon #Upscale #SciLit

I'm a co-author here! Join me on a read through of this paper 1/n

Geostatistics in soils are often ignored with significant opportunities for misinterpretation of carbon storage resulting from interventions. Slessarev etal 2023 https://doi.org/10.1111/gcb.16491 takes us back to stats class, highlighting regression to the mean effects and normalization artifacts. #SoilCarbon #SoilPractices #agricultural #CitationMine #Geostatistics #SciLit

Soils of old growth forests are NOT necessarily at steady state. Gaines in soil organic carbon stocks (~30%) were are seen in one southern China preserve from 1979 to 2003. Zhou etal 2006 https://www.science.org/doi/10.1126/science.1130168 #SoilCarbon #SoilPractices #SoilSampleDesign #SciLit

Deep soils respire only 10% of total CO2 (>30cm) despite holding most of the SOC (~50%). Fresh litter also tends to stay on top and not make it's way deeper (13C tagged litter addition). Wordell-Dietrich etal 2020 https://doi.org/10.5194/bg-17-6341-2020 used 2m deep and 1.6m diameter soil observatories to continuously monitor soils at 10, 30, 50, 90 and 150 cm; measuring CO2, SOC, 13C (tagged surface litter addition), and 14C. #SoilDataSource #SoilCarbon #DeepCarbon #SciLit

Soil fractionation offers one way to try to tease out soil carbon dynamics beyond bulk. Using a linear-mixed effects model and large soil carbon database ( #ISRaD ) Heckman et al 2022 https://doi.org/10.1111/gcb.16023 found that depth was critical in explaining soil carbon stocks and persistence. Many traditional ClORPT variables were also explanatory, except for NPP, though their effects of different fractions differed. #SoilCarbon #DataCollection #Reanalysis #sciLit

Soil carbon estimates associated with #agricultural practice shifts need a portfolio approach to measurement, monitoring, and verification. But it is not a hopeless case and deeper data (on sample design, practice description, etc) can help. Bradford et al 2023 https://www.sciencedirect.com/science/article/pii/S0016706123003968 looked at high density (0.1 ha sample-1) sample collections from 45 fields to support power analysis for #SoilCarbon shift detection. #SoilBGC #DataScience #SoilSampleDesign #SciLit

Australia's #SafeguardMechanism allows #fossilfuel projects to proceed as long as Type 1 & 2 emissions are offset. But what if those #carbonoffsets are based on a flawed and still being researched methodology... like #soilcarbon?

We helped Kimberly Cornish (Food Water Wellness Foundation) develop methods for monitoring SOC stocks for large areas and at high spatial resolution. It's been a tremendous effort and we learned so much. You can now also follow the key results from here: https://www.facetsjournal.com/doi/full/10.1139/facets-2023-0040

Hey science peeps! Interested in #soilcarbon and #climatechange? Listen to some of the heavy-hitters talk about the limits to carbon storage on September 7th.

Soil carbon is a vital resource for food production and climate mitigation, but it is often degraded by human activities. A new study identified the key factors influencing soil carbon sequestration and loss. Farmers and land managers can adopt better practices to enhance soil health and reduce greenhouse gas emissions.

Just finished skim reading this study on urban lawns and grasslands soil carbon sequestration. It is an important meta-analysis contributing to addressing urban climate emissions.

"High soil carbon sequestration rates persist several decades in turfgrass systems: A meta-analysis." (OpenAccess)

I did a fair amount of reading on Soil Organic Carbon from turf grasses when I researched my literature review on Synthetic Turf in 2021, and this article pulls a lot of information from numerous studies together..
