Taxonomy record sources: POWO (CC BY 4.0), USDA_PLANTS_CATALOG (Public Domain). Loaded from the botanica open cultivated-plant knowledge base and the GBIF backbone; each row keeps its origin.
What the sources say it wants
Each line shows the band, then the kind of source and the citation. "Published" means the number is printed on the cited page; "derived" means it was computed from published numbers with the formula recorded on the row; "external API" rows are refreshed nightly from a live source; "curated" rows are OAT's own working values from June 2026.
Whole cycle
| Zone | Measure | Band | Source |
|---|---|---|---|
| Root zone | Root-zone EC (dS/m) | up to 3.5 (warning above 6, alert above 9.8) | published: FAO Irrigation and Drainage Paper 29, 1985 |
Keystone status
Partial. The KEEP rule asks for a growth stage and a band in each of light, air and root zone before a crop counts as complete; this plant is in the keystone with what its sources give so far.
Generated 2026-09-15 from the OAT plant keystone. Source types and citations are carried on every row; the keystone snapshot that the Library instruments read is plant-targets.json and its quality sheet is plant-targets.quality.json.
