@FarmerTheta It is very rare here. Usually only when the weeds from a droughted out crop are going to prevent the crop from being harvested. In this scenario it is almost always fed to animals.
@MudDck85@DanielTurnerPTF Def is about .28 of 46. or 12.88% Fertilizer. So it is about 40% the fertilizer of 32-0-0 normal liquid. They sell def by the gallon lets say wholesale delivered is $1.75. 32-0-0 $3.2 per gallon So def would have to sell for $1.28 to compare. These are rough numbers.
