Carbon action MULTA Finnish carbon sequestration experimental field dataset 2022

This dataset includes the third year observations of the Finnish Carbon Action carbon sequestration experiment. In the experiment c.a. 100 farms test carbon farming methods on a test field and an adjacent control plot. Of these 20 farms were chosen for continued sampling 2020-2024 combining field observations and soil sampling. This data will be coupled with satellite imagery, field sensors and carbon cycle modeling to forecast carbon sequestration. Subsequent sampling will track changes in soil carbon stock and soil productivity.

The dataset will be updated annually, updates are published as separate datasets in https://zenodo.org/communities/carbonaction/ . The 2022 update includes data on:

• physical quality: soil structure (VESS), bulk density, porosity, water holding capacity, infiltration rate
• biological properties: earthworm counts, above ground biomass, plant cover (%), chlorophyll
• chemical properties: soil nitrogen pools

This version does not currently include the soil nitrogen pools or water holding capacity. They and site photos will be published in an updated release.
