阶段清单
Soil preparation
Before sowing
Apply basal NPK according to local recommendations; incorporate residues or manure where available.
At planting
Sowing
Place starter phosphate near the seed row when soils are cold or low in P.
Tillering
Early tillering / knee-high
Top-dress nitrogen in one or two splits if the crop looks N-hungry; avoid late N that delays maturity.
Heading
Boot to heading (as advised locally)
Only apply late N when grain protein or yield response is expected; follow extension rates.

FAQ: fertilizing Sorghum
When should I fertilize Sorghum?
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。
