Fertilizer schedule
Use the stage cards as a planning checklist, then read country notes for local fertilizer language (rates are not prescriptions).
Work in compost or well-rotted manure; add a balanced basal dressing if soil tests low in P/K.
Band a light starter fertilizer near the row; avoid burning young roots with high-salt products.
Side-dress with nitrogen for leafy growth if leaves pale; water in thoroughly.
Shift toward potassium and steady moisture for fruiting vegetables (tomato, pepper, cucurbits).

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.
Treat them as historical/field guidance, not a prescription for your plot. Units and products differ by country. Confirm with agricultural extension before applying.
Not a fertilizer prescription. Over-application wastes money and can harm plants and waterways. Follow local extension packages.
