FAQ: fertilizing Sunflower
When should I fertilize Sunflower?
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。
