Carbon action MULTA Finnish carbon sequestration experimental field dataset 2023

This dataset includes the fifth and final 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 2019-2023 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 health.

This dataset is an update of the final monitoring year and includes summaries of the previous year measurements. The full measurements for previous years can be found in:  https://zenodo.org/communities/carbonaction/ .

The 2023 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, microbial activity, root biomass
• chemical properties: soil nutrients, change in nutrient pools over time

The nutrient analysis, water holding capacity, microbial activity, root biomass and site photos will be published in an updated release during winter 2023-2024.
