Thinning turned an upland forest into a temporary carbon source and made a peatland forest an even stronger carbon source | University of Helsinki A recent study highlights how forest thinning significantly influences the ability of forests to store or release carbon.

Aerial view on the 60 plots of the TWINWIN experiment surrounded by grass and agricultural fields. The plots vary in color that represent the different undersown treatments. In the background is a road, buildings and forests. The sky is blue with some white clouds.

🚨📃🧪 New paper out: "Impacts of diverse undersown cover crops on seasonal soil microbial properties". Rashmi Shrestha used the #TWINWIN experiment to show that undersowing crops with diverse plant mixtures, particularly including legumes has beneficial effects on soil microbial life and function 1/6

Kannanotto: Luonnonvarakeskus vastaa kritiikkiin hiilitaselaskelmista - Metsälehti "Asian käsittely oli yksipuolista ja kritiikki perustui merkittävältä osin tietämättömyyteen ja väärinymmärryksiin."

Oivallinen ja perusteellinen vastine Juha Mikolalta ja Paavo Ojaselta @luke.fi kasvihuonekaasuinventaarin hiilitaselaskelmiin kohdistuneeseen kritiikkiin. www.metsalehti.fi/artikkelit/k...

Orpon hallitus piti kiinni kiistellyistä kriteereistä vanhoille metsille – järjestöt: ”Farssi” ja ”totaalinen rimanalitus” Hallitus päätti lahopuun määrää ja puuston ikää koskevista kriteereistä, joiden perusteella se suojelee vanhat metsät. Suojelua edellyttää EU.

Mielestäni nyt on asiallisen ja kriittisen katsauksen paikka.

- Miksi tuota 👇 päätöstä on -ihan perustellusti- kyseenalaistettu?

Radiocarbon analysis reveals underestimation of soil organic carbon persistence in new-generation soil models Abstract. Reflecting recent advances in our understanding of soil organic carbon (SOC) turnover and persistence, a new generation of models increasingly makes the distinction between the more labile s...

Or in fact, up to 80 cm depth… 😁

Fungal communities in boreal soils are influenced by land use, agricultural soil management, and depth Fungal communities in boreal soils are influenced by land use and agricultural soil management down to the 40–80 cm soil layer, and symbiotrophic fungi bec

How do the fungal communities look like in conventional and organic farming compared to natural meadow? Laura Häkkinen dug deep into this topic, up to 70 cm! First PhD paper and Editor’s choice in FEMS! Have a look: academic.oup.com/femsec/artic...

I would like to join, too!

Happy World Soil Day! And Welcome to Finnish Soil Science days in January 7-8th 2025. Scientific programme launched today (mostly in Finnish but also English stuff). www.maapera.fi

Wow, looks great!

Controlled soil monolith experiment for studying the effects of waterlogging on redox processes Climate change induced mild and rainy winters may expose soils to more frequent and prolonged waterlogging in boreal regions. Resulting oxygen depleti…

Doctoral Researcher (PhD student) in Process Modelling The University of Eastern Finland is inviting applications for a Doctoral Researcher position in Process Modelling at the Department of Environmental and Biological Sciences on the Kuopio campus. The

I have an open PhD position that will focus on process modeling and parameter inference in soil microbial processes (methane and nitrogen cycle, stable isotope experiments & natural abundance, soil gas transport).

I would say 1) protect the existing SOC with improved management, soils tend to loose C. 2) use always the best practises, if lucky, you can sequester some SOC! The column had the right message but e.g. the saturation or N limitation story may not be essential as reaching saturation is minimal risk…

Investigating the complementarity of thermal and physical soil organic carbon fractions Abstract. Partitioning soil organic carbon (SOC) in fractions with different biogeochemical stability is useful to better understand and predict SOC dynamics and provide information related to soil he...

A paper out where MAOC/POC is compared with RockEval thermal analysis. Great work by Amicie Delahaie and the team, including the EJP Soil FREACs consortium. 'both methods can be seen as complementary and potentially relevant for soil monitoring'
