Northern Illinois | AA is the cheapest form of N. However it is the most expensive for of N to apply when you factor toolbar cost,maintenance,repair,tank pulling,fuel and time. Each operator has to factor true cost when he is figuring what AA costs for him to apply. If you are hiring it done vs doing it yourself there is a cost difference. Even doing it yourself a toolbar is not free whether you own or rent. Every time you break a knife or shank it is pricey (for those of us that have rocks). Guys hiring it done have a sunk cost in the first pass spraying so often they don't factor that App charge into the price of 32 because they are paying to get it sprayed regardless. Also after a warm wet fall/winter like much of the central corn belt had you have to factor cost of N serve and loss on fall applied N.
All that being said I like NH3 an awful lot. It is very stable when managed correctly. Hard to argue that a guy side dressing NH3 is not getting the ultimate N program from a stability side. It's just not the cheapest product to apply BUT it is the cheapest to buy. | |
