Fertilization
Nitrogen Fertilizer Issues

Economics


Production cost up
N fertilizer prices up



Availability


Homeland security issues
Nitrosamine concerns


Price tied to natural gas
Transportation costs up
Tobacco companies want less N applied
Quality concerns

Too little:


thin body, poor yield
Too much:

delayed maturity, fat stems
Alternative N Sources

Dolomitic – Ammonium Nitrate (27% N)

Ammonium nitrate mixed with lime


78% ammonium nitrate
Theoretically similar to ammonium nitrate

Can impregnate some chemicals ?
Relatively high cost?
 Availability (Bagged)
 Limited practical experience

Alternative N Sources



Sodium Nitrate (16% N)
Calcium Nitrate (15.5% N)
Sodium-Potassium Nitrate
(15% N)





Immediate uptake (good for
sidedress)
Good for low pH soils
Erratic availability
High cost
Low analysis – high transport
cost
Alternative N Sources

Pesticide Concerns

Illegal pesticides


Could void contract
Indiscriminant use of labeled pesticides
Endosulfan (Golden Leaf)
 MH

Do not use at or after topping
Current Sucker Control
Recommendation

Reduce MH rate and add a local systemic


1.5 gal MH + 0.5 gal Butralin, Flupro or
Prime+
Use Coarse nozzles

TG-3 or TG-5 full cone nozzles
