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

本数据集涵盖芬兰碳行动（Finnish Carbon Action）固碳（carbon sequestration）试验的第五年及最终年度观测数据。该试验中，约100家农场在试验田及相邻对照样地开展碳农业（carbon farming）方法试验。其中20家农场被选为2019—2023年持续采样对象，采样工作结合野外观测与土壤取样开展。该采样数据将结合卫星影像、野外传感器数据与碳循环模型，用于固碳量预测；后续采样将追踪土壤碳库与土壤健康状况的变化。

本数据集为最终监测年度的更新版本，包含前一年度测量数据的汇总内容。过往年度的完整测量数据可通过以下链接获取：https://zenodo.org/communities/carbonaction/。

2023年更新版包含以下类别的数据：
物理性质：土壤结构（VESS）、容重、孔隙度、持水量、入渗速率
生物性质：蚯蚓数量、地上生物量、植被盖度（%）、叶绿素含量、微生物活性、地下生物量
化学性质：土壤养分、养分库随时间的变化量
