It occurs to me that part of the price drop is due to Chinese competition.
Like the US of a while back, China is staggering under the impact of really nasty coal fueled air and water pollution.( China has vast amounts of low quality coal).
They are already beginning to clamp down on coal burning big time.
The average folks income in China is rising and our's is sinking fast.
Given the costs of shipping fertilizer across the ocean, their competitive advantage
is due to fade in the near future.
UAN is cheap!
But low...sell high!
