Crop samples, soil samples, and measured properties (field or laboratory) through wet properties
Metadata elements for documenting crop samples, soil samples, and measured properties either in the field or laboratory through wet chemistry.

| Metadata element | Description | Example |
|---|---|---|
| Unique identifier | Unique metadata identifier: e.g. UUID (Universally Unique Identifier) | 123e4567-e89b-12d3-a456-426614174000 |
| sampledFeature | Material sample: e.g. soil, leaf sample, stem sample, grain sample | Soil samples for the field cultivated with rice |
| sourceLocation | Where the sample was collected | Jolanda Di Savoia, Ferrara; XY coordinates (Coordinates UTM-EPSG:32632) |
| storageLocation | Where the sample is stored | University of Milano Bicocca |
| samplingTime | When the sample was collected | April 2023 |
| size | Sample size (e.g. weight in g) | |
| SamplingProcedure | How the samples was collected or prepared | The samples have been collected from 10 Elementary Sampling Units (ESU) (10 ESU in total) and in each ESU, there are 4 plots each of 15*15 m.<br>For each plot, 5 soil samples were collected with a core cotter. These 5 samples were mixed together forming a unique soil sample per plot. Collected soil samples belonged to the top layer of the surface (15-20 cm) |
| Procedure | The analysis method: e.g. ICP-EOS instrument | extraction with barium chloride or ammonium acetate solution and determination by atomic absorption spectroscopy-FAAS |
| observedProperty | The analysed property (e.g. generally concentration of a constituent) | Ca2+ |
| result | The result of the analysis | Measured values |
| unit of measurement | reference quantity chosen from a unit equivalence group | cmol(+) kg-1 |
| resultTime | Analysis date | 15.03.2024 |
