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).
Excerpts from CropWhen calendar notes that mention fertilizer, manure, NPK, or related terms.
basal dressing = 40 tde manure / ha, 100 U of N / ha, 150 U P / ha, 200 U K / ha: manure maintenance N = 03 appoorts 40 u / ha each 100 U K / ha 3rd contribution: irrigation = 4000- 6000m3 / ha. (Greenhouse)

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.
