📢 New paper alert! We explored N₂O fluxes in tropical cloud forests of Réunion Island. Soils emit negligible N₂O, and leaves & canopy soil have nirK and nosZ type denitrifiers.

☁️ The canopy #microbiome might help mitigate N₂O.

Today, I presented a study based on GHG and related #microbiome in Réunion Island #peatland forests at the 12th #INTECOL Wetlands Conference, Tartu, #Estonia

The new global methane budget is now out! Seems to gloss over the measured 25-50Tg sink term in upland trees that was recently discovered (= or > to soil sink & prob more subject to change). Possibly because it’s not yet been included in models the authors use. Observations do matter though…
1/3

The new Global Methane Budget is now published, open access.

📢 New paper alert. We explored CH₄ fluxes in tropical cloud forests on Réunion Island.

🌱 Peat soils = CH₄ sinks
🌳 Tree stems = mild CH₄ sinks
🍃 Leaves = potential methanogen hotspots!
☁️ Canopy microbiomes matter more than we thought.

Hands-on with the hidden world: our master’s students are investigating soil and rhizome microbiomes from peatland forests, learning essential techniques like DNA extraction and qPCR to understand microbial community dynamics.

Fertilized soils are a major source of N₂O, a potent greenhouse gas. Our latest study by @lkuusemets.bsky.social shows how nitrogen (N) fertilization rates, manure amendments, and crop types influence N₂O emissions and nitrogen use efficiency (NUE).

Interactions of fertilisation and crop productivity in soil nitrogen cycle microbiome and gas emissions
Abstract. Fertilised soils are a significant source of nitrous oxide (N2O), a highly active greenhouse gas and a stratospheric ozone depleter. Nitrogen (N) fertilisers, while boosting crop yield, also...

New research alert!

Pristine peatlands act as carbon sinks but emit CH4, while disturbed ones release more CO2 & N2O. However, climate change is reshaping these ecosystems.
