Soil preparation
1–3 weeks before sowing/transplant
Work in compost or well-rotted manure; add a balanced basal dressing if soil tests low in P/K.
At planting
Sowing or transplant day
Band a light starter fertilizer near the row; avoid burning young roots with high-salt products.
Vegetative growth
2–4 weeks after establishment
Side-dress with nitrogen for leafy growth if leaves pale; water in thoroughly.
Flowering / fruiting
At flowering / early fruit set
Shift toward potassium and steady moisture for fruiting vegetables (tomato, pepper, cucurbits).

FAQ: fertilizing Yam
When should I fertilize Yam?
Follow the stage cards above (soil prep → planting → mid-season). Exact rates depend on soil tests and local packages — FAO notes below show how growers describe fertilization in different countries.
Can I copy NPK numbers from the notes?
Treat them as historical/field guidance, not a prescription for your plot. Units and products differ by country. Confirm with agricultural extension before applying.
非施肥处方。过量施肥浪费成本并可能污染水体。请咨询当地农技部门。
