Metadata research draftEvidence limits

⚠️ Status: drafted from the literature survey. Values Unknown until source notes/full text.

Soil type and texture

Section titled “Soil type and texture”
  • Grows on a broad range; prefers well-drained, fertile soils. Specific preferences Unknown.

Drainage

Section titled “Drainage”
  • Sensitive to waterlogging / poor drainage (warm-season, shallow-rooted). Drainage requirement flagged as important — Unknown until sources. Relates to the salt/irrigation papers.

pH

Section titled “pH”
  • Tolerates a wide pH range; salinity/alkalinity tolerance noted (see below). Preferred pH range Unknown; refinement needed.

Salinity

Section titled “Salinity”
  • Several studies cover amaranth under salt stress (candidates: 10.1590/1983-40632016v4742580, 10.3389/fpls.2021.604481). Tolerance is species/cultivar-dependent — Unknown for grain types until sources.

Organic matter / base fertility

Section titled “Organic matter / base fertility”
  • Responsive to organic fertility (compost, manure) — candidates 10.1016/s0304-4238(01)00305-3. Base fertility need Unknown.

Preparation

Section titled “Preparation”
  • Fine, firm seedbed suited to tiny seed; preparation/method at small scale Unknown (see planting.md).

Structured-data impact

Section titled “Structured-data impact”
  • Feeds soil fields of data/crops/amaranth.yaml. Drainage and salinity are the highest-value flags for this crop.
