Continuing with the series of photos related to nitrogen fertilizer, a crop duster applies urea to rice fields near Almyra, Arkansas. Who cannot admire a crop duster pilot? I'm sure every job has its hazards, but a crop duster pilot puts their life on the line every workday, every second of that day, just to make a living. One mistake and it's all over. Why would anyone do it? There is the adrenaline rush, but some of the answer is surely the fun of flying the crop duster planes. They are the muscle cars of the sky, a relic of an era when things were made to last, not the cheap plastic junk of today. A crop duster grips the air and must have power to spare to pull the heavy plane away from danger. So it is not surprising that these large engines suck gas, something like 60 to 80 gallons of aviation fuel an hour. As such, it makes it an expensive way to get nitrogen to a crop, but it is the only way feasible for a flooded rice field in a country with relatively high labor costs. Overall, growing rice in Arkansas takes a lot of resources in terms of energy and water to produce a harvest. And I'm sure if you dug a little deeper you would find that there are costs to the taxpayer, too, in terms of farm subsidies, but that is beyond the scope of this story. So one may ask why not grow rice somewhere else where it is not such a drain on resources? That might not sound like a good idea to a rice farmer in Arkansas.
