Corn 施肥日程

先看阶段卡片,再读各国笔记。剂量不是处方。

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 Corn

When should I fertilize Corn?

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。
