### Mappings and Rationale
- **Generic Seed:** The term \`seed\`, \`spores\`, and \`spawn\` use heavy metal concentrations calculated as a linear average of all cereal grains and oilseeds (11 crops total) from the SALCA \`plants_feed\` category. A standard dry matter of 86% was used.
- **Tubers and Bulbs:** \`tubers\`, \`bulbs\`, \`corms\`, and \`rootCuttings\` were mapped to the specific concentrations for \`potatoes\` provided by SALCA, reflecting their high water content (20% DM) and similar geological uptake profiles.
- **Young Plants and Cuttings:** \`seedlings\`, \`saplings\`, \`suckers\`, and \`stemCuttings\` were mapped to the \`main product, mean\` values from SALCA, using a representative dry matter of 48% to reflect their non-dormant, vegetative state.
