Moringa — Fertilization

Metadata research draftEvidence limits

⚠️ Status: drafted from the metadata-level literature survey (research/moringa/report.md). Values Unknown until source notes (S-####) and full text. Not cultivation, nutrition, or medical advice.

Fertility candidates

• Planting density × nitrogen fertilization effects on biomass and chemical composition (candidate 10.1007/s10457-012-9525-5).
• Sources and rates of organic and NPK fertilizers vs soil chemical properties and growth (candidate 10.1007/s40093-017-0175-5).
• Nitrogen and phosphorus effects on growth and leaf nutrient composition (candidate 10.3389/fsufs.2022.861400).
• Vermicompost and NPK effects on seed and fixed-oil production under calcareous soil (candidate 10.3390/plants10101998) — output here is seed/oil, not leaf; keep results separate.
• Rates, timings, and formulations from all of these: Unknown until full text.

System dependence and interactions

• Fertility interacts with density × cutting frequency in leaf systems (see planting.md); a household tree, an orchard, and a dense cut stand differ in nutrient removal and expected response. Evidence must stay separate per system.
• Nutrient removal per output (leaf vs pod vs seed) — Unknown.

Organic amendments at household scale

• Organic-source candidates exist (see 10.1007/s40093-017-0175-5, 10.3390/plants10101998); compost/manure rates for a garden tree or a small leaf bed — Unknown.

Micronutrients and soil testing

• Deficiencies, micronutrient needs, and recommended pre-plant soil analyses: Unknown.

Exclusions

• No medical or nutritional-therapy claims; papers applying moringa extract to other crops are not cultivation evidence.

Structured-data impact

• Feeds fertility of data/crops/moringa.yaml: nitrogen, phosphorus, potassium, organic_amendments.
