Carbon action MULTA Finnish carbon sequestration experimental field dataset 2021

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 2021 update includes data on: physical quality: soil structure (VESS), bulk density, porosity, water holding capacity, infiltration rate, aggregate stability biological properties: earthworm counts, above ground biomass, plant cover (%), chorophyll chemical properties: change in soil nutrients 2019 to 2021, change in OM and CO2 burst This version of the dataset includes only the field monitoring results of July 2021. The soil nutrient analysis and monitoring photographs will be uploaded in the next update.
