Fertilized Corn with 15-0-15

Calculations per ChatGPT – The Plan using the old seeder…but, the old belt had dry-rotted and broke.

For sweet corn like G-90 sweet corn in south Alabama soils, using 15-0-15, a good practical seasonal target is usually:

• 1.5–2.0 lb actual nitrogen per 100 ft of row total
• Since 15-0-15 is 15% nitrogen, that equals:

$$\frac{1.5 \text{ to } 2.0}{0.15} = 10 \text{ to } 13.3 \text{ lb fertilizer per 100 ft}$$0.151.5 to 2.0?=10 to 13.3 lb fertilizer per 100 ft

So your total seasonal 15-0-15 would typically be 10–13 lb of 15-0-15 per 100 ft row

If feeding at least 3 times between VE and silking, divide that into lighter applications. A solid schedule would be:

Stage	Amount of 15-0-15 per 100 ft row
VE to V2	3–4 lb = 2 lbs per 50 ft row
V5–V6	3–4 lb
V10–V12 (before tassel)	3–5 lb

Total: ~10–13 lb per 100 ft
